摘要：Efficient activation of CO2 at low temperature was achieved through the interface effect between In2O3 and ZrO2 by their geometric and electronic effects. The results show that 75In(2)O(3)-25ZrO(2) (In2O3 : ZrO2 molar ratio of 3 : 1), as a catalyst for the reverse water gas shift reaction, can achieve 28% CO2 conversion with 96% CO selectivity at 400 degrees C, 0.1 MPa, a H-2 : CO2 molar ratio of 3 : 1 and a gas hourly space velocity of 10 000 mL g(-1) h(-1). In situ FTIR experiments provide a basis for clarifying the pivotal role of formate (facilitated at In2O3-ZrO2 interface) in this reaction.
