Enhancement of stability and activity of Cu/ZnO/Al2O3 catalysts by colloidal silica and metal oxides additives for methanol synthesis from a CO2-rich feed

A series of Cu/ZnO-based catalysts were prepared through co-precipitation and alternative pH precipitation methods by adding small amount of colloidal silica (0.6wt.%) and Mn, Ga and Zr oxides for methanol synthesis from a CO2-rich feed. The prepared catalysts were characterized by a variety of tech...
