Many factors, such as the functionalized supports, solvents and ligands, could influence their activities and reuse performances greatly. These immobilized catalysts also offer the industrial advantages such as easy separation.展开更多
A novel Ni-Co/SiO2 catalyst which exhibits high activity and excellent anti-carbon deposition property for CO2 reforming of CH4 to synthesis gas is developed.
Titanium-modified (-alumina supported CuO catalyst has been prepared and used to methanol synthesis from CO_2 hydrogenation. The addition of Ti to the CuO/(-Al_2O_3 catalyst made the copper in the catalyst exist in m...Titanium-modified (-alumina supported CuO catalyst has been prepared and used to methanol synthesis from CO_2 hydrogenation. 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
