The addition of Ti to the CuO/(-Al_2O_3 catalyst made the copper in the catalyst exist in much smaller crystallites. The effect of the loading of Ti on the activity and selectivity to methanol from CO_2 hydrogenation was investigated. The activity was found to increase with the increasing of surface area of metallic copper, but it is not a linear relationship.展开更多
