摘要：

The reverse water-gas shift (RWGS) reaction is an important reaction from the viewpoint of converting CO2 into CO as an important raw material compound. As the RWGS reaction is a mildly endothermic and competitive reaction with CO2 methanation, it is important to improve the activity at low temperatures. Here, we report PtW nanoparticles (NPs) supported on gamma-Al2O3 (PtW NPs/Al2O3) in which Pt and W were randomly mixed for obtaining a highly active and selective catalyst for the RWGS. At low temperatures of 200 and 300 degrees C, PtW NPs/Al2O3 exhibited 16- and 17-times higher activity than Pt/Al2O3, one of the most promising catalysts. The enhanced activity of PtW NPs originated from alloying Pt with W, which contributes to the sintering resistance of Pt NPs, and promotion of CO2 adsorption and CO desorption on the catalyst. Furthermore, PtW NPs/Al2O3 exhibited high durability and excellent catalytic performance.
