NO Reduction on Cu-Based Model Catalysts Studied by in-situ IRAS
文献摘要：
Cu-based catalyst has been widely used for catalytic reduction of NO.Well-defined TiOx/Cu(110)films were prepared and investi-gated by in situ reflection absorption infrared spectroscopy(IRAS),Auger electron spectroscopy(AES)and low energy electron dif-fraction(LEED).A complex surface structure of Cu+(-O-Ti-)-O-Cuδ+/Cu(110)was proposed,in which the topmost surface Cu+is highly dispersed,isolated and fixed by the TiOx layer.Such a'single atom'-like surface site appears a very narrow vco peak at 2130 cm-1,and is more stable upon both CO reduction and vacuum annealing than the Cu2O/Cu(110).Such isolated Cu+(-O-Ti-)site on TiOx/Cu(110)is also fairly stable in NO+CO reaction,but the overall catalytic activity is slightly lower than that on the Cu(110)surface,indicating that the single-atom Cu+(-O-Ti-)site is less efficient for NO+CO reaction at the examined conditions.The study provides useful infor-mation for the design and application of single-atom catalysts and understanding the nature of catalytically active centers.
