Co-based catalysts exhibit high activity for C-C coupling in the Fischer-Tropsch synthesis unit, however, they tend to produce primarily C1 hydrocarbons (CO or CH4) during CO2 hydrogenation. Here, a novel 0.04RuCo/MnO-500 catalyst photothermocatalytic hydrogenation, exhibiting conversion of 65.6% and value-added (C2+) selectivity 63.2% (excluding CO) under mild conditions is reported. The time-yield C2+ over reaches 8.2 mmolCH2 gcat -1 h-1, which 3.0-fold 3.3-fold higher than that Co/MnO-500 (2.7 h-1) 0.04Ru/MnO-500 (2.5 h-1), respectively. Further investigations disentangle exceptional performance should be attributed interface sites between Co Ru within catalyst. presence interfacial enhances ability adsorb activate intermediate (*CO) produced achieving low CO promoting production with conversion. This work presents approach developing Ru/Co directly converting into through realizing demand sustainable energy sources.
