Efficient activation of CO2at low temperature was achieved by reverse water-gas shiftviachemical looping (RWGS-CL) by virtue of fast oxygen ion migration in a Cu-In structured oxide, even at lower temperatures. Results show that a novel Cu-In2O3structured oxide can show a remarkably higher CO2splitting rate than ever reported. Various analyses revealed that RWGS-CL on Cu-In2O3is derived from redox between Cu-In2O3and Cu-In alloy. Key factors for high CO2splitting rate were fast migration of oxide ions in the alloy and the preferential oxidation of the interface of alloy-In2O3in the bulk of the particles. The findings reported herein can open up new avenues to achieve effective CO2conversion at lower temperatures.
