抄録/ポイント： 3元触媒反応中の1wt%Rh/Al_2O_3触媒におけるRh化学種の動的挙動を,マイクロガスクロマトグラフ,NO_x計,四重極質量分析計,及び時間分解高速X線吸収分光法(XAS)測定を用いて調べた。組合せデータは,ガスが還元から酸化雰囲気へスイッチされ,逆になると,Rh種の異なる表面再配列挙動,ランダム還元過程,および自己触媒酸化過程を示唆した。本研究は,不均一触媒反応のための強力なオペランドXASシステムの実行と,触媒の活性金属種の動的挙動を理解するための重要性を実証した。Copyright 2019 American Chemical Society All rights reserved.
