Abstract

Catalysts based on Cu/CuO-ZnO supported on mesoporous carbon (FDU-15) were synthesised and tested for methanol production from CO2 and H 2. The catalytic activity was strongly dependent on the method by which the Cu and Zn components were loaded onto the carbon support. Three synthetic methods were trialled and the materials produced were characterised by various techniques. The materials with better contact between the Cu/CuO and ZnO particles were catalytically more active towards methanol production (CZC-3>CZC-2>CZC-1). The methanol production rate for CZC-3 (7.3mmolg-1h-1) was higher, on a catalyst weight basis, than that of a commercial catalyst (5.6mmolg-1h-1). Also, CZC-3 had a higher turnover frequency (1.8×10-2s-1) than the commercial catalyst (0.2×10-2s-1). This work demonstrates that Cu/CuO and ZnO particles supported on mesoporous carbon, prepared by an appropriate method, are promising catalysts for methanol synthesis from carbon dioxide.
