  Scientific journal, Abstract
  
  The urgent need for sustainable CO₂ management has driven the development of efficient catalytic systems capable of converting CO₂ into value‐added chemicals under mild conditions. Herein, we report a Ni₉Pd₁ catalyst with a low Pd content (Ni/Pd = 9:1) for the selective CO₂ hydrogenation to formate at low temperatures. Remarkably, this catalyst exhibits exceptional versatility, efficiently hydrogenating both aqueous (bi)carbonate and CO₂ captured from air (as carbonate) to formate. Moreover, this catalyst shows appreciable robustness by achieving cumulative formate yields of 770.5 mmol g_Pd⁻¹ (TON of 82, STY of 32.18 mmol_formate g_Pd⁻¹ h⁻¹ at 28 °C) and 1371.9 mmol g_Pd⁻¹ (TON of 146, STY of 57.16 mmol_formate g_Pd⁻¹ h⁻¹ at 80 °C) over multiple cycles. The synergistic Ni‐to‐Pd interaction in this catalyst leads to the efficient CO₂ activation and H₂ dissociation, enabling operation under mild conditions. This study demonstrates an integrated and sustainable approach where CO₂ captured from air can be hydrogenated to formate at low temperature.

  Scientific journal, Cardanol, an unsaturated long‐chain alkylphenol derived from agricultural waste, has potential as a sustainable substrate for bio‐based phenol production. Herein, the potential of hydrocardanol, readily obtained through cardanol hydrogenation, is demonstrated as a viable feedstock for phenol production via trans‐alkylation using toluene as the alkyl acceptor. H‐ZSM‐5 (SiO₂/Al₂O₃ molar ratio = 80) exhibits a 53.7% phenol yield with a high phenolics balance (86.7%) from a 10 wt% hydrocardanol solution at full conversion in a batch reactor. In contrast, cardanol gives only 27.1% phenol under the same reaction conditions. This improved yield with hydrocardanol is attributed to suppressed formation of bi‐ and/or polycyclic phenols via self‐alkylation, due to the higher thermal stability of the saturated side chain. Realkylation of the desired phenol product largely limits the phenol yield. The model reaction experiments with phenol and 1‐pentadecene show that the reaction proceeds via hydrocardanol dealkylation on the zeolite, followed by rapid isomerization, cracking and oligomerization reactions of the resulting long‐chain olefin, and realkylation of toluene and phenol. This indicates that phenol alkylation could be suppressed by reducing the hydrocardanol‐to‐toluene ratio. This approach is validated in a fixed‐bed flow reactor, achieving a high phenol yield (>95%) with a high carbon balance (>99%).

  Scientific journal, Abstract
  
  Developing efficient catalytic processes for obtaining biobased monomers for plastics can significantly contribute to a more sustainable economy. The biomass‐derived and chemical platform 5‐hydroxymethylfurfural (HMF) can be converted to various key intermediates, which is often hampered by side reactions due to the reactive nature of the formyl group in HMF. Here, we present a stepwise approach involving a protecting agent to obtain dimethyl furan‐2,5‐dicarboxylate (MFDC), which is a monomer for polyalkylene furanoates, a new class of biobased polyesters. Methanol is used as a solvent, reactant, and protecting agent for HMF's formyl group. In the first step, the oxidative esterification of the hydroxymethyl group to methyl carboxylate in HMF‐dimethylacetal catalyzed by Au/CeO₂ affords methyl 5‐formylfuran‐2‐carboxylate dimethylacetal (MFFC‐acetal) in high yields (>90 %) from concentrated methanolic solutions (~20 wt %). Without protecting agent, a mixture of methyl‐5‐hydroxymethylfuran‐2‐carboxylate (MHMFC), MFDC, and humin byproduct was obtained. The deprotection of MFFC‐acetal in the second step proceeded efficiently in acetone with Amberlyst‐15, affording MFFC in a >90 % yield. In the final step, oxidative esterification of MFFC in methanol (10 wt %) afforded MFDC in a 93 % yield using Au/CeO₂. The acetal protection strategy with methanol offers an efficient route toward MFDC in two oxidative esterification steps.

  2022年度、マンガンやコバルトなどの遷移金属元素を含むスピネル型複合酸化物について、光触媒である酸化ガリウム上でのナノ形態制御を行ったところ数原子層～5 nm程度の膜厚の量子薄膜が得られた。今年度はこれらを用いて水溶液中での二酸化炭素光還元反応を行ったが、二酸化炭素還元活性は低かった。そこで当初想定いていたスピネル型構造のみならず、二酸化炭素還元活性が報告されている銅やスズをベースとした結晶性酸化物についてまずは二酸化炭素還元活性を評価したのち、ナノ構造制御を進めることとした。
  酸化銅(Ⅱ)を光触媒である酸化ガリウム上にさまざまな方法で担持した。二酸化炭素光還元反応では、光による電子の励起過程と励起した電子による二酸化炭素の還元過程が両方とも機能しなければ活性を示さないため、まずは後者を評価するために電極触媒活性を評価した。酸化ガリウムのみでは活性が低く、また水溶液中では水の還元による水素生成が優先的に起こるため二酸化炭素還元の選択率は低かったが、酸化銅と酸化ガリウムを複合化すると酸化銅(Ⅱ)単独に比べ活性が3倍以上に向上し、一酸化炭素の生成量が大幅に向上することを見出した。
  一方、スズを含む酸化物として酸化スズ(Ⅱ)、酸化スズ(Ⅳ)、水酸化酸化スズを合成し、水溶液中での二酸化炭素還元反応を行ったところ水溶液中にもかかわらず二酸化炭素還元反応の選択率が80％以上となり、特に水酸化酸化スズでは90%を超えた。またいずれの試料も二酸化炭素還元時にそのほとんどが金属スズへと還元された。電気メッキで電析した金属スズ薄膜では、二酸化炭素還元反応の選択率は55%程度であったことから、反応前のスズの状態がその活性、選択性に大きく影響することを明らかにした。

  YFI（YNU-5）型ゼオライトについては脱Al後にメチルナフタレン環のメチル化・トランスメチル化挙動を幅広く解析した．嵩高い2-メチルナフタレンのみを原料とする反応では異性化が進行し，触媒劣化が遅く，大細孔からアクセス可能な強ブレンステッド酸点によってトランスメチル化が速やかに進行し，そのような場合には劣化が起きにくいことが実証された．大細孔はあるがその中に強ブレンステッド酸点を持たないMOR（モルデナイト）型ゼオライトでは劣化が速かった．またYFIで小さなメタノールも原料として加えるとメチル化・トランスメチル化の両方が進行したが，両反応とも速やかな速度低下を示し，小さな分子が小細孔に入って副反応を起こし強ブレンステッド酸点を被覆することが示唆され，析出物やミクロ細孔特性の解析から裏付けられた．
  YFIゼオライトのシリカ被覆では，ここまで書いたように触媒劣化が顕著であり，また被覆によって活性の低下が激しいものの，2-メチルナフタレンとメタノールから2,6-および2,7-ジメチルナフタレンのみを選択的に生成することができた．
  シリカ塩基処理MFI（YNU-5）型ゼオライトにおいては塩基処理の程度を増すと，まず①外表面酸点が増加し，つぎに②外表面積が増加し，最後に③Al濃度が増す3段階の変化がそれぞれ起きることがわかった．ポリプロピレン分解活性は②と対応しており，ポリプロピレンがその一端をミクロ細孔に侵入させて反応していることが明らかとなった．既に嵩高い分子形状を持つ溶媒を使うと形状選択的にポリオレフィンだけを分解できることを示しているが，機構が明らかとなった．
  前年までに，開いた空間に突き出た強ブレンステッド酸点のCo種にベンゼンが強く吸着するため，メタンによるベンゼンのメチル化反応が進行することをおおよそ明らかにしていたが，今年度出版した．他に多数の学会・論文発表を行った．

  未利用資源の有効利用などのため，大細孔強ブレンステッド酸性の触媒が求められる．YFI (YNU-5)型ゼオライトの酸性質をアンモニアIRMS-TPD法および量子化学計算で解析し，強ブレンステッド酸点が狭いisolated 8-ring (以後i8r)に存在することと，広い12-12-8-ring system (以後12rS)側の分子と反応する機構がわかった．
  簡便で大スケールの合成法を確立した．厳しい条件での酸処理により12rS側から脱Alが起き，Si-migrationが促進され，（水）熱安定性が向上し，i8rの強ブレンステッド酸点を残し，強度を保ったままブレンステッド酸点濃度を調節できることがわかった．DTO反応において高度脱Al体（Si/Al = 287）では，反応初期にまずi8r由来酸点がまず失活し，その後は12rSで主に反応が進行することが示唆された．
  脱Al YFIゼオライトは，大細孔強ブレンステッド酸性の触媒が求められるナフタレン・2-メチルナフタレンのメタノールによるメチル化，2-メチルナフタレンの異性化，ポリプロピレンの分解に活性を示し，2-メチルナフタレンの不均化には不活性であった．ピログルタミン酸の水素化に対するRu触媒には大細孔強ブレンステッド酸性の担体が求められ，YFIゼオライトは高活性をもたらした．ナフタレン類のメタノールによるメチル化では劣化が速く，i8rにメタノールだけが入って重合したためと推測される．
  以上，欠点はあるものの，YFIゼオライトが未利用資源の有効利用に資する大細孔強ブレンステッド酸性の触媒・担体として機能することがわかった．
  劣化を抑制するため，i8rを選択的に塞いだのちにH+を復活させることを意図し，Agイオン交換-還元を試みたところ，i8rに選択的にAgが位置する兆候を得た．

  In this study, we developed new synthesis methods of brownmillerite-type or spinel-type solid solution oxides ultrasmall particles with single-nanometer dimensions, which are electrocatalysts for oxygen evolution reaction, using a reverse micelle method or a solvothermal method. Wavenumber of the ultrasmall particles of all solid solution oxides were shorter than those of the bulk ones. The catalytic activity of the solid solution oxides for oxygen evolution reaction were largely improved by decreasing particle size to with single-nanometers, and they acted as cocatalysts of photocatalysts for water splitting using visible light.

• One-pot conversion of glutamic acid to 2-pyrrolidone over solid catalysts

  SUGANUMA Satoshi
  Glutamic acid, an abundant nonessential amino acid, was converted into 2-pyrrolidone in the presence of a supported Ru catalyst under a pressurized hydrogen atmosphere. This reaction pathway proceeded through the dehydration of glutamic acid into pyroglutamic acid, subsequent hydrogenation, and the dehydrogenation-decarbonylation of pyroglutaminol into 2-pyrrolidone. In the conversion of pyroglutaminol, Ru/Al2O3 exhibited notably higher activity than supported Pt, Pd, and Rh catalysts. IR analysis revealed that Ru can hydrogenate the formed CO through dehydrogenation-decarbonylation of hydroxymethyl groups in pyroglutaminol and can also easily desorb CH4 from the active sites on Ru. Furthermore, Ru/Al2O3 showed the highest catalytic activity among the tested catalysts in the conversion of pyroglutamic acid. Consequently, the conversion of glutamic acid produced a high yield of 2-pyrrolidone by using the supported Ru catalyst.

Liquid phase separation of aromatics and aliphatics was enabled, and parameters in the kinetics of separation, which controlled the performance, were clarified. For partial hydrogenation of naphthalene into tetralin, 100% of naphthalene was converted into tetralin with a 99% selectivity on a dispersed molybdenum oxide monolayer catalyst, derived from phosphomolybdic acid). For the decomposition of tetralin, molybdenum-added * BEA zeolite showed a tetralin conversion of 95% and selectivity into LPG / alkylbenzene of 85%.

  Quantum chemistry calculations show that the compression from both ends of SiOAl gave a high ability to accept negative charge, and the twisting of SiOAl to stretch it weakened the covalent bond of O-cation. The activation enthalpy of the catalytic reaction reflected the difference in heat of ammonia adsorption, and its relationship with the activation entropy revealed how the reaction rate was determined.
  An alumina coating with controlled macropores by anodic oxidation under high voltage and pore widening in an aqueous phosphoric acid solution from an aluminum substrate. From the relationship between the size and depth of the macropores and the dispersion of the zeolite precursor, a structured material in which the MFI zeolite precursor was filled in almost all pores was obtained.

  We have developed ionic liquids that dissolved cellulose or lignin; 1-methyl-1-(2-methoxyethyl)pyrrolidinium([P1ME]) 2,5-diaminohexanoate ([P1ME][Lys]) easily dissolved both lignin and cellulose. On the other hand, 1-methyl-1-(2-methoxyethyl)pyrrolidinium acetate ([P1ME][OAc]) dissolved cellulose selectively. Further, we accomplished strong acid or strong base-catalyst free acylation of cellulose using [P1ME][OAc].It was found that the cellulose solution of [P1ME][OAc] was treated with 2,2,2-trifluoroethyl benzoyl ester at 80°C to afford the corresponding cellulose benzoate with a perfect degree of substitution in excellent yield.

  This study aimed efficient use of glycerol made as a byproduct through the conversion process of biomass resources. Dehydration of glycerol into acrolein was performed using various solid acids, and it revealed the relation between acid properties and the catalytic activity. Moreover, I investigated oxidehydration of glycerol, forming acrylic acid in one-pass process. The catalysts were prepared by loading of Mo-V-O as oxidation active species on ZSM-5, exhibiting high selectivity of acrolein. The investigation of the ratio of SiO2/Al2O3 in ZSM-5 and the loading amount of Mo-V-O found the catalyst forming acrylic acid.

  当該年度では柔軟な骨格をもつ高活性なカーボン固体酸の合成と水中で機能するルイス酸触媒の構築に成功した.これまでの知見では,カーボン固体酸の高い触媒活性は高密度のスルホ基と反応基質を取り込んでスルホ基へ効率よくアクセスさせる柔軟なカーボン骨格に由来することを見出した.本研究では,ポリ塩化ビニルを炭化・スルホ化して得られるカーボン固体酸がより柔軟かつスルホ基を高密度に固定したカーボン骨格を有し,セロビオース加水分解反応において既報のカーボン固体酸の約3倍の高い活性を示した.高活性な固体酸創出は,硫酸代替触媒として従来の化学工業プロセスの環境負荷低減に寄与するキーテクノロジーであり,本研究の成果はそれを推進する上で重要な第一歩である.また,カーボン固体酸の活性向上を図る具体的な方法を確立する基礎検討の側面を含んでおり,学術的側面からも重要な知見である.
  分子触媒を固定化したカーボン材料の開発はメソポーラスカーボンに導入したスルホ基を足場とする方法を試みた.当初の研究計画に従いカーボンにルイス酸触媒を固定化し酸化触媒として応用したが,均一系錯体触媒と比較して十分な触媒性能を示さずカーボン骨格が分解する結果となった.そこで,固体表面に存在する欠損サイトをベースに分子触媒と類似の機能を創出させることを検討した.様々な遷移金属酸化物の表面酸性質を検討したところ,V族遷移金属酸化物(Ta_2O_5,Nb_2O_5)が水中でも働く特異的なルイス酸触媒特性を示すことがわかった.本触媒の触媒性能を必須化学品の一つである乳酸の合成反応で評価したところ,従来の錯体触媒を上回る高い活性・選択性を示すことを見出した.系統的な検討までは到達していないが,これまで報告例がない固体の水中機能ルイス酸の触媒特性および発現機構の解明は学術面・工業面でも重要な知見を与えると期待できる.
