CO2 methanation is a vital reaction for converting waste energy into alternative fossil fuels. Among existing catalysts, nickel is a promising player regarding its high selectivity and low cost. In this research, acidified carbon nanotube (A-CNT) supported Nicore@Pdshell nanoparticles (NPs) with surface decoration of Tetramethoxysilan (TMOS) is synthesized by two steps wet chemical reduction method as a thermocatalyst in the CO2 reduction reaction (CO2RR). Upon thermal reduction, the H2 from TOMS decomposition or the feed gas triggers the polymerization of CO2 into high carbon chain as C3 products found in CO2 and H2 mixing gas.
