Preparation of Methanol Synthesis Catalyst Cu/ZnO/Al2O3 by Gel-network Coprecipitation Method

A novel gel-network-coprecipitation process has been proposed to prepare ultrafine Cu/ZnO/Al2O3 catalysts for methanol synthesis from CO2 hydrogenation. Compared to the catalysts prepared via theconventional coprecipitation method, the new catalysts prepared via gel-network-coprecipitation methodexhibit much higher BET surface area and metallic copper specific surface area, much smaller crystallitesize and higher catalytic activity and selectivity in CO2 hydrogenation to methanol. The effect of the gelconcentration of gelatin on the structure, morphology and the catalytic properties of the Cu/ZnO/Al2O3catalysts for methanol synthesis from hydrogenation of carbon dioxide were also investigated.
