Scientific journal, A bent crystal Laue analyser (BCLA) is an X-ray energy analyser used for fluorescence X-ray absorption fine-structure (XAFS) spectroscopy to separate the fluorescence X-ray emission line of a target atom from the elastic scattering X-rays and other fluorescence emission lines. Here, the feasibility of the BCLA for total reflection fluorescence XAFS (TRF-XAFS), which has a long X-ray footprint on the substrate surface owing to grazing incidence, was tested. The focal line of the BCLA was adjusted on the X-ray footprint and the XAFS signal for one monolayer of Pt deposited on a 60 nm Au film with high sensitivity was obtained. Although range-extended XAFS was expected by the rejection of Au fluorescence arising from the Au substrate, a small glitch was found in the Au L
₃ edge because of the sudden change of the complex refraction index of the Au substrate at the Au edge. This abnormal spectrum feature can be removed by reflectivity correction using Au foil absorption data. BCLA combined with TRF-XAFS spectroscopy (BCLA + TRF-XAFS) is a new technique for the in situ surface analysis of highly dispersed systems even in the presence of a liquid overlayer.

A log-spirally bent crystal Laue analyzer has been investigated and developed for highly sensitive in situ surface X-ray absorption fine structure (XAFS) measurement. Both calculations and experiments were conducted to obtain its intensity distributions on the different positions of the analyzer. A home-made log-spirally bent crystal Laue analyzer was made and evaluated. It was revealed that higher XAFS signals were obtained with the home-made analyzer than with the commercial one.

固体高分子形燃料電池の酸素還元電極触媒としては主に白金系合金が用いられているが、埋蔵量やコスト面に問題を抱えているため、安価かつ高活性な非白金系酸素還元電極触媒の開発が近年盛んに行われている。本発表では、銅系酸素還元電極触媒の中で特に高い触媒活性を示す銅二核錯体触媒に着目し、その高い触媒活性を示す理由を解明するためにin situ XAFS測定を行ったので、その結果に関して報告する。

Pdナノ粒子は脱硝触媒、部分水素化触媒等で広く用いられる。Pdナノ粒子において，ナノ粒子化すると格子が拡張するという奇妙な現象が報告されてきた．本研究では，この格子拡張をEXAFSで直接調べ，Pd-Pd結合の伸長に起因することを確認し，また水素吸蔵に伴う現象でないことをしめした．この奇妙なナノ粒子に関する現象について，可能性を議論したい．

Micro Reverse Monte Carlo Approach to EXAFS Analysis. e-Journal of Surface Science and Nanotechnology

English, Scientific journal, We have developed a new Reverse Monte Carlo code, called the micro Reverse Monte Carlo (m-RMC), which is applicable to structure analysis of nanomaterials and surface species. In the m-RMC, Reverse Monte Carlo is applied to an ensemble of replica files, each of which contains one molecule or one small cluster, because the Extended X-ray Absorption Fine Structure (EXAFS) is sensitive to short-range structures and has negligible interaction between molecules or clusters. We apply the m-RMC to face-centered cubic metals (Cu, Pd, and Pt) and discuss the advantages, validation, and problems of the m-RMC. The bond distance and some cumulant coefficients can be determined from the EXAFS using m-RMC. Some 50-100 replica files are sufficient to reproduce the EXAFS oscillations and radial distributions. The bond distance can be determined, including the asymmetric distributions,by m-RMC. We also apply m-RMC to α-MoO₃ and Au clusters. The m-RMC analysis of MoO₃ shows that three radial distribution peaks appear corresponding to three types of Mo–O bonds. The m-RMC analysis of Au cluster indicates the presence of Au₅₅ cuboctahedral structure with Au-Au distance at 0.288 nm. We obtain a 3 D image of Au₅₅ nanocluster from the unified file. The m-RMC method can be applied to the analysis of the EXAFS for chemical systems with appropriate care. [DOI: 10.1380/ejssnt.2014.322]

Japanese, Scientific journal, Well-defined inhomogeneous α-Sb₂O₄/VSbO₄ catalysts were prepared using an electron lithography method to investigate the effects of µm order structures on an atomic scale catalytic reaction. X-ray photoelectron spectroscopy (XPS) and laser microscopy revealed that µm order structures were successfully developed on a Si substrate where an α-Sb₂O₄ micro line with a controlled width was deposited on VSbO₄. We carried out a propene partial oxidation reaction on this surface and found that the acrolein formation rate was significantly influenced by the width and interval of the α-Sb₂O₄ µm line. The results of this study indicate the possibility of controlling the surface reaction by the inhomogeneity of the surface structure in the µm order.

金属のdバンド中心は、様々な触媒反応の活性序列を示す良い指標である。dバンド中心は第一原理計算によって求めるが、種々の金属やバイメタル系に対して網羅的に計算を行うのは、計算・時間コストが高くなる。そこで本研究では，金属の密度，イオン化エネルギー等の入手容易な物理量を記述子とし、種々の金属・合金のdバンド中心の機械学習による高速予測を検討し，その結果、妥当な精度で予測できることを実証した。, 公益社団法人 日本表面科学会, Japanese

本年度は、まず、昨年度設計・製作を行ったオペランド偏光全反射蛍光XAFS装置の性能向上及び最適化に向けた試みを行った。真空度改善のため、真空排気ラインのコンダクタンスを大きくするとともに、排気に使用しているターボ分子ポンプを、より排気速度の大きいポンプへと変更した。こうした試みにより、真空度は2桁程度改善した。また、装置に取付けられている蛍光取り出し用のBe窓（ICF70規格のフランジ中央部にBe薄膜をろう付け）の有効径を可能な限り大きくし、試料と半導体検出器（19素子solid state detector）との距離及び立体角の最適化を行うことで、スペクトルのS/N比向上を実現した。
続いて、アルミナ単結晶表面上に白金ナノ粒子を担持したモデル触媒表面（Pt/α-Al2O3(0001)）でのCO酸化反応中のPt活性点電子状態及び3次元構造について、昨年度得られた結果の再現性もかねて、再度オペランド偏光全反射蛍光XAFS測定（Pt L3吸収端）を行った。反応ガス（CO、O2及び濃度補正用Arを含む混合ガス）雰囲気下で試料を加熱し、各温度で反応進行状況を確認しながらXANES測定を行ったところ、温度の上昇に伴ってスペクトルのwhite line強度は減少した。このことは温度上昇により、Ptが徐々に還元されたことを示している。活性は>473 Kで顕著になることがわかった。さらに、493 KでCO酸化反応が進行中のEXAFS測定にも成功し、スペクトルは三次元構造解析に十分なS/N比であった。予備的な解析から1 nm程度のナノ粒子が活性点であることを見出し、FEFFコードを用いた三次元構造決定を開始した。

Synthesis and atomic-level characterization of well-defined surface nanostructures for development of novel catalytic materials

We have developed oxide-supported metal catalysts and immobilized metal complex catalysts which are highly efficient for purification of environment and green organic synthesis by combining atomic-level surface characterization using single-crystal model catalyst surfaces. We particularly focused on molecular activation at characteristic nanostructures formed at the metal-oxide interfaces in the oxide-supported metal catalysts, while in the immobilized metal complex catalyst we examined the effects of catalytic activity on spatial arrangement and orientation of the surface-attached metal complexes. A novel approach to find efficient catalytic materials with high-speed and high-precision based on the informatics-based techniques was also explored.

Catalytic properties such as activity and selectivity of oxide-supported metal catalysts strongly depend on metal cluster size and metal-support interaction. In this research project, we tried to develop a method to prepare gold clusters with a small size distribution in the range of single atom-10 nm on a titanium dioxide single crystal surface by using ligand-protected gold clusters, and the structures of the deposited gold clusters were examined at the atomic level by surface science techniques such as STM/AFM and polarization dependent total-reflection fluorescence XAFS. We also developed a ultra-high vacuum equipment for measuring catalytic activity of the deposited gold clusters formed on an oxide single crystal surface.
