Abstract:

Ru/MnCO₃ catalyst with metal-carbonates interfaces exhibits superior catalytic selectivity and anti-CO stability in CO₂ methanation in comparison with Ru/MnO catalyst, benefiting from enhanced CO₂ and H₂ dissociation, formation of active Ru–CO* intermediates, and further rapid transformation into CH₄.
