摘要：CO2 hydrogenation to methanol over efficient catalysts is a significant approach for achieving carbon neutrality. Here we present a CuZn/MC catalyst with enriched Cu+ active sites fabricated through one-step introduction of dispersed Cu-ZnO interfaces on the surface of coconut shell derived mesopore biochar (MC). The CuZn/MC catalyst exhibits a high space-time yield of methanol reached 121.25 gMeOH center dot Kgcat -1 center dot h-1 with excellent stability more than 50 h at 260 degrees C, almost triple that of the CuZn/SiO2 catalyst. Controlled experiments confirm that the MC facilitates the highly dispersed Cu species with low valence states, owing to the high specific surface area, narrow mesopore distribution and reducibility of MC. The one-step introduction of bimetal promotes the dispersion and interaction of Cu-ZnO interfaces. The abundant Cu+ sites with high binding energy improve the CO2 hydrogenation to methanol over CuZn/MC catalyst. This work offers a new strategy for constructing efficient biomass derived biochar supported catalysts for methanol synthesis.
