Catalytic conversions of CO2 to methanol with renewable H2 represent a promising pathway to mitigate global warming problem and to find an alternative way to replace depleting fossil fuel reservoirs. In the present study, CO2 hydrogenation to methanol was carried out over CuZnZrOx catalyst where the effects of polymorph structures of ZrO2 such as amorphous, monoclinic and tetragonal structures were investigated with the incorporation of active CuO and ZnO. The influences of single and binary meal oxides on the physiochemical properties and catalytic performances were investigated with respect to the phases of ZrO2. The binary CuO-ZnO exhibits a better performance with monoclinic ZrOx structures owing to the higher density of H2 and CO2 adsorption sites as well as formation of defected Zn-ZrOx solid solutions on the catalyst surface. |
