The catalytic CO2 reduction by CH4 to synthesize fuels of CO and H2 (CRM) supplies a prospective technology to address the global warming effect caused by greenhouse gas of CO2. Due to its highly endothermic characteristics, CRM can only proceed at high reaction temperature, resulting in excessive energy consumption and quick catalyst deactivation due to serious carbon. Herein, we report a nanocomposite of Ni/CeO2 that exhibits high catalytic activity and good stability with focalized UV–vis-Infrared (UV–vis-IR) illumination without applying ...
