Mechanistic insights into electrocatalytic carbon dioxide conversion to methane via carbon monoxide pathways on PdCo catalyst

The conversion of CO2 into value-added products is of significant interest in mitigating greenhouse gas emissions and the global energy crisis. PdCo alloy is a promising catalyst for CO2 conversion; however, no previous studies to date have focused on determining the reaction mechanisms and activity of the conversion of CO2 to methane (CM conversion) on this alloy.Notably, CO poisoning is a key issue in transition metal catalysts; therefore, we focused omn CM conversion via the CO formation pathway to establish whether the hydrogenation steps of CO succeed on the PdCo alloy. Our results revealed that hydrogenation processes are feasible with small thermodynamic barriers. Additionally, we gained physical insights into the interactions between the reaction intermediates and the PdCo catalyst.
