Measures for CO2 capture and utilization [1], [2] are urgently required to mitigate global warming. Numerous studies have been conducted on the physical or chemical capture of CO2 and its subsequent conversion via hydrogenation with green hydrogen into fuels or valuable chemicals, such as methane and methanol [3], [4], [5], [6], [7], [8]. Recently, a novel thermochemical process integrating CO2 capture and conversion using dual-function materials (DFMs) was proposed [9], [10], [11], [12], [13].
