English, Scientific journal, Optimizing processes and materials for the valorization of CO2 to hydrogen carriers or platform chemicals is a key step for mitigating global warming and for the sustainable use of renewables. We report here on the hydrogenation of CO2 in water on ZnO-supported CuAu nanoalloys, based on ≤7 mol % Au. Cux Auy /ZnO catalysts were characterized using 197 Au Mössbauer, in situ X-ray absorption (Au LIII - and Cu K-edges), and ambient pressure X-ray photoelectron (APXP) spectroscopic methods together with X-ray diffraction and high-resolution electron microscopy. At 200 °C, the conversion of CO2 showed a significant increase by 34 times (from 0.1 to 3.4 %) upon increasing Cu93 Au7 loading from 1 to 10 wt %, while maintaining methanol selectivity at 100 %. Limited CO selectivity (4-6 %) was observed upon increasing temperature up to 240 °C but associated with a ≈3-fold increase in CO2 conversion. Based on APXPS during CO2 hydrogenation in an H2 O-rich mixture, Cu segregates preferentially to the surface in a mainly metallic state, while slightly charged Au submerges deeper into the subsurface region. These results and detailed structural analyses are topics of the present contribution.

Catalysts, 13, 8, 1155, 1155, MDPI AG, 26 Jul. 2023
Scientific journal, Ultrafine layered double hydroxides (LDHs) have abundant hydroxy groups at their edge sites, serving as anchor sites for metal NPs. Furthermore, transformation of ultrafine LDHs into mixed metal oxides (MMOs) generates abundant oxygen vacancies, which are advantageous for O2 activation during Au-catalyzed CO oxidation. We used ultrafine Ni-Ti LDHs with low crystallinity or Ni-Ti MMOs supported on SiO2 onto which Au NPs were deposited by deposition–precipitation (DP) and DP–urea (DPU). The catalytic activity of the Au catalysts was significantly affected by the preparation method, with the highest activity obtained by depositing Au onto LDH/SiO2 by DPU, followed by transformation of LDH to MMO (Au/Ni-Ti MMO/SiO2 (LDH-DPU)). The presence of Au on LDHs affected the transformation of LDHs into MMOs, resulting in LDH-DPU having the greatest number of oxygen vacancies in the TiO2 domain in MMOs. Consequently, the adsorbed or the lattice oxygen on the surface of LDH-DPU can be easily utilized for CO oxidation at low temperatures. Moreover, the catalytic activity of LDH-DPU increased with water vapor concentration up to 100% relative humidity at room temperature, suggesting the potential of Au/Ni-Ti MMO/SiO2 as an air purification catalyst.

English, Scientific journal, Au nanoparticles are efficient catalysts for selective oxidations. The interaction between Au nanoparticles and supports is critical for achieving high catalytic activity. Herein, Au nanoparticles are supported on a zeolitic octahedral metal oxide based on Mo and V. The charge of Au is controlled by the surface oxygen vacancies of the supports, and the redox property of the zeolitic vanadomolybdate is highly dependent on Au loading. The Au-supported zeolitic vanadomolybdate is used as a heterogeneous catalyst for alcohol oxidation under mild conditions with molecular oxygen as an oxidant. The supported Au catalyst can be recovered and reused without the loss of activity.

Gold/Substituted Hydroxyapatites for Oxidative Esterification: Control of Thin Apatite Layer on Gold Based on Strong Metal-Support Interaction (SMSI) Results in High Activity.

English, Scientific journal, Gold nanoparticles (Au NPs) deposited on various cation- and anion-substituted hydroxyapatites (Au/sHAPs) show oxidative strong metal-support interaction (SMSI), wherein a thin layer of the sHAP covered the surface of the Au NPs by heat treatment in an oxidative atmosphere. Calcination of Au/sHAPs at 300 °C caused a partial SMSI and that at 500 °C gave fully encapsulated Au NPs. We investigated the influence of the substituted ions in sHAP and the degree of the oxidative SMSI on the catalytic performance of Au/sHAPs for oxidative esterification of octanal or 1-octanol with ethanol to obtain ethyl octanoate. The catalytic activity depends on the size of the Au NPs but not on the support used, owing to the similarity of the acid and base properties of sHAPs except for Au/CaFAP. The presence of a large number of acidic sites on CaFAP lowered the product selectivity, but all other sHAPs exhibited similar activity when the Au particle size was almost the same, owing to the similarity of the acid and base properties. Au/sHAPs_O2 with SMSI exhibited higher catalytic activity than Au/sHAPs_H2 without SMSI despite the fact that the number of exposed surface Au atoms was decreased by the SMSI. In addition, the oxidative esterification reaction proceeded even though the Au NPs were fully covered by the sHAP layer when the thickness of the layer was controlled to be less than 1 nm. The substrate can access the surfaces of the Au NPs covered by the thin sHAP layer (<1 nm), and the presence of the sHAP structure in close contact with the Au NPs resulted in significantly higher catalytic activity compared with that for fully exposed Au NPs deposited on the sHAPs. This result suggests that maximizing the contact area between the Au NPs and the sHAP support based on the SMSI enhances the catalytic activity of Au.

English, Scientific journal, Transesterification of ethyl-10-undecenoate (derived from castor oil) with 1,4-cyclohexanedimethanol over a recyclable Cu-deposited V2O5 catalyst afforded 1,ω-diene, the corresponding cyclohexane-1,4-diylbis(methylene) bis(undec-10-enoate), a promising monomer for the synthesis of biobased polyesters, in an efficient manner. Deposition of Cu plays an important role in proceeding the reaction with high selectivity, and both the activity and the selectivity are preserved for five recycled runs by the addition of the substrates. The present catalyst was effective for transesterification with other alcohols, especially primary alcohols, demonstrating a possibility of using this catalyst for efficient conversion of plant oil to various fine chemicals.

Praseodymia–titania mixed oxide supported gold as efficient water gas shift catalyst: modulated by the mixing ratio of oxides

RSC Advances, 12, 9, 5374, 5385, 2022, [International Magazine]
English, Scientific journal, Modulating the active sites for controllable tuning of the catalytic activity has been the goal of much research, however, this remains challenging. The O vacancy is well known as an active site in reducible oxides. To modify the activity of O vacancies in praseodymia, we synthesized a series of praseodymia-titania mixed oxides. Varying the Pr : Ti mole ratio (2 : 1, 1 : 2, 1 : 1, 1 : 4) allows us to control the electronic interactions between Au, Pr and Ti cations and the local chemical environment of the O vacancies. These effects have been studied study by X-ray photoelectron spectroscopy (XPS), CO diffuse reflectance Fourier transform infrared spectroscopy (CO-DRIFTS) and temperature-programmed reduction (CO-TPR, H2-TPR). The water gas shift reaction (WGSR) was used as a benchmark reaction to test the catalytic performance of different praseodymia-titania supported Au. Among them, Au/Pr1Ti2O x was identified to exhibit the highest activity, with a CO conversion of 75% at 300 °C, which is about 3.7 times that of Au/TiO2 and Au/PrO x . The Au/Pr1Ti2O x also exhibited excellent stability, with the conversion after 40 h time-on-stream at 300 °C still being 67%. An optimal ratio of Pr content (Pr : Ti 1 : 2) is necessary for improving the surface oxygen mobility and oxygen exchange capability, a higher Pr content leads to more O vacancies, however with lower activity. This study presents a new route for modulating the active defect sites in mixed oxides which could also be extended to other heterogeneous catalysis systems.

English, Scientific journal, AbstractGold (Au) can be deposited as nanoparticles (NPs) smaller than 10 nm in diameter on a variety of metal oxide (MOx) NPs. Au/MOx have high catalytic performance and selective oxidation capacity which could have implications in terms of biological activity, and more specifically in modulation of the inflammatory reaction. Therefore, the aim of this study was to examine the effect of Au/TiO₂, Au/ZrO₂ and Au/CeO₂ on viability, phagocytic capacity and inflammatory profile (TNF-α and IL-1β secretion) of murine macrophages. The most important result of this study is an anti-inflammatory effect of Au/MOx depending on the MOx nature with particle internalization and no alteration of cell viability and phagocytosis. The effect was dependent on the MOx NPs chemical nature (Au/TiO₂ > Au/ZrO₂ > Au/CeO₂ if we consider the number of cytokines whose concentration was reduced by the NPs), and on the inflammatory mediator considered. The effect of Au/TiO₂ NPs was not related to Au NPs size (at least in the case of Au/TiO₂ NPs in the range of 3–8 nm). To the best of our knowledge, this is the first demonstration of an anti-inflammatory effect of Au/MOx.

Catalytic Activities of Various Niobium Oxides for Hydrogen Absorption/Desorption Reactions of Magnesium
Keita Shinzato, Hiroyuki Gi, Toru Murayama, Masahiro Sadakane, Yongming Wang, Shigehito Isobe, Takayuki Ichikawa, Hiroki Miyaoka
ACS Omega, 6, 36, 23564, 23569, American Chemical Society (ACS), 14 Sep. 2021, [International Magazine]
English, Scientific journal, Five types of niobium(V) oxides (Nb2O5) were synthesized by hydrothermal and heat treatment processes, and their structural properties and catalytic activities for the hydrogen absorption/desorption reactions of magnesium were characterized. The synthesized Nb oxides were dispersed on magnesium hydride (MgH2), a typical hydrogen storage material, using the ball-milling method. All the synthesized Nb oxides improved the reaction kinetics of the hydrogen desorption/absorption reactions. The catalytic activities for the hydrogen desorption were comparable, while the hydrogen absorption rates were significantly different for each synthesized Nb oxide. This difference can be explained by the structural stability of Nb2O5, which is related to the formation of a catalytically active state by the reduction of Nb2O5 during the ball-milling process. Notably, the highest catalytic effect was observed for Nb2O5 with a highly crystalline pyrochlore structure and a low specific surface area, suggesting that pyrochlore Nb2O5 is a metastable phase. However, only the amorphous Nb oxide was out of order, even though there is a report on the high catalytic activity of amorphous Nb oxide. This is attributed to the initial condensed state of amorphous Nb oxide, because particle size affects the dispersion state on the MgH2 surface, which is also important for obtaining high catalytic activity. Thus, it is concluded that Nb2O5 with lower stability of the crystal structure and smaller particle size shows better catalysis for both hydrogen desorption and absorption reactions.

Proceeding of Annual/Fall Meetings of the Japan Petroleum Institute, 2019, 0, 175, 175, The Japan Petroleum Institute, 2019, [Peer-reviewed]
Japanese,
Bulk vanadium oxide-based NH₃-SCR catalysts were considered for denitration at a low temperature below 150^oC. Vanadium oxalate as a precursor was calcined at 270^oC for 1-4 h to synthesize vanadium oxide catalysts including tetravalent and pentavalent vanadium atoms. The NO conversions and reaction rates of these catalysts for NH₃-SCR were greater than those of titania supported vanadium oxide catalysts and V₂O₅ catalyst that consist only of pentavalent vanadium. It was indicated that the existence of tetravalent vanadium leads to a decrease in the activation energy.

水溶性ニオブ錯体を水熱処理することによって結晶性のニオブ酸が合成できる。得られたニオブ酸はブレンステッド酸とルイス酸を有しており、それらの酸触媒サイトは吸着水存在下において塩基性プローブ分子と相互作用することができる。この触媒をトリオース水溶液に加えて加熱したところ、約80%の収率で乳酸が生成した。高い触媒活性は水中で機能するルイス酸およびブレンステッド酸の有効酸量が大きいためであると考えられる。, The Japan Petroleum Institute, Japanese

Synthesis of trigonal Mo-V-M-O (M = Fe, W) catalysts by using structure-directing agent and catalytic performances for selective oxidations of ethane and acrolein

Crystalline trigonal Mo-V-M-O (M = Fe, W) catalysts were obtained by using structure-directing agent. Trigonal Mo-V-O is a layered structure and the cross-section is comprised of the netwark structure based Mo pentagonal unit and V octahedral, forming pentagonal, hexagonal, and heptagonal channels in the structure. Fe was located in the hepgatonal channel and W was placed at the Mo pentagonal unit by substituting Mo. Mo-V-O and Mo-V-W-O showed almost the same catalytic activity for the selective oxidations of ethane and acrolein, on the other hand, the activities decreased by the location of Fe inside the channel. Clear relationship in catalyst structure and catalytic activity was found., The Japan Petroleum Institute, Japanese

Zhang Zhenxin, Izumi Shoko, Murayama Toru, Ueda Wataru, Proceeding of Annual/Fall Meetings of the Japan Petroleum Institute, 2012, 0, 122, 122, 2012
A novel microporous complex metal oxide based on molybdenum, vanadium, and bismuth (Mo-V-Bi oxide) was synthesized by hydrothermal method and characterized by STEM, TEM, XRD, FT-IR, Raman, TPD, NH3-TPD, and N2 adsorption. The results showed that Mo-V-Bi oxide was crystalline material with high porosity and surface area. The single crystal of Mo-V-Bi oxide was obtained for single crystal analysis to gain full structural information of this material. This material was used as a heterogeneous catalyst for olefin epoxidation with TBHP. The stable catalyst could be reused for several times without loss of activity., The Japan Petroleum Institute, Japanese

Hydrothermal Synthesis of Complex Metal Oxides by Assembling MO6 Octahedra and Creation of Solid Acid
Grants-in-Aid for Scientific Research
01 Apr. 2012 - 31 Mar. 2015
MURAYAMA Toru
Layered-structure-type tungsten based complex oxides (W-M-O, M= Ti, Zr, Nb, Ta) were synthesized by the hydrothermal method. The synthesized W-M-O showed characteristic peaks at 2θ = 22.7° and 46.2° in an X-ray diffraction pattern (Cu-Ka), indicating linear corner-sharing of MO6 octahedra in the c-direction. The same layered-type materials were obtained with a wide range of W and M composition ratios by using soluble precursors. The catalytic activity of W-M-O increased with increase in the W ratio, suggesting that strong acid sites were generated. From Raman and adsorption measurements of W-M-O with various crystalline structures, it was revealed that the crystalline motif of W-M-O in the a-b plane was an interconnection of MO6 octahedra and {M6O21} pentagonal units and micropore channels but without long-range order.

Structure engineering of functional solid catalysts has been conducted on the basis of unit-network methodology of molecular-type polyoxide units under hydrothermal condition for creating three-dimensional network structure of the units. The methods were applied to metal oxide components in 6, 5 and 4 element group and successfully gave various solids with nano-size structure with a heptagonal structural unit, confirming the applicability of the method for creating high-dimensional solid structures. This method was also found useful for creating a new three-dimensional zeolite-type porous solid based on molecular-type polyoxide units. The materials are totally new and showed unique adsorption property for CO2 and ethane. These obtained materials showed solid-acid property and incomparable catalytic property based on an asymmetric porous structure.
