Cu/Ni-loaded oxygen vacancy-rich CeO2 rod derived from metal organic framework for efficient photothermal CO2 hydrogenation

Photothermal catalytic CO2 reduction can combine photocatalysis and thermal catalysis by using full-spectrum solar energy to convert CO2 into high value-added chemicals. This can effectively alleviate the problems of excessive CO2 emissions and thermal catalytic energy waste. In this paper, a novel catalyst was prepared using Ce-MOF as a precursor to generate Cu/Ni/CeO2 for efficient reduction of CO2 to CO by hydrogenation. Due to the rod-like structure of CeO2 and the high dispersion of Cu and Ni nanoparticles, 10
