Methanol demand is continuously increasing in the chemical and energy industries. However, it is still desirable to develop an efficient catalyst to attain a high yield of methanol from direct CO2 hydrogenation. In the present study, roles of gallium (Ga) oxide on bimetallic Ga-ZrOx catalyst synthesized by different methods was investigated. The Ga-ZrOx catalyst prepared by co-precipitation method exhibited high CO2 conversion and superior selectivity towards methanol. The high activity was linked to the strong metal support interactions, degree of oxygen vacant sites and exposed content of GaOx. |
