The catalytic conversion of CO2 to methanol using green hydrogen generated from renewable energy sources is a promising path toward carbon neutrality.The catalyst employed in the CO2 hydrogenation to methanol technology is a ZnO-CeO2 bimetallic oxide.Various preparation methods such as impregnation，co-precipitation，precipitation coating，and physical mixing were investigated.Characterization techniques including X-ray diffraction（XRD），N2 adsorption-desorption，carbon dioxide temperature-programmed desorption（CO2-TPD），hydrogen temperature-programmed desorption（H2-TPD），scanning electron microscopy（SEM），and X-ray photoelectron spectroscopy（XPS） were utilized to analyze the physicochemical properties of the ZnO-CeO2 bimetallic oxide catalyst and its impact on the catalytic performance in CO2 hydrogenation to methanol.The results indicated that the preparation method significantly influenced the physicochemical properties and catalytic performance of the catalyst.The ZnO-CeO2 catalyst prepared by co-precipitation exhibited excellent catalytic performance.Under reaction conditions of temperature of 300 ℃，pressure of 4 MPa，and weight hourly space velocity of 19 600 mL/（g·h），the CO2 conversion rate reached 4.61%，methanol selectivity achieved 80.64%，and the methanol space-time yield reached 244.96 mg/（h·g）.It was observed that high concentration of oxygen vacancies，strong H2 activation capability，large specific surface area，and pore volume were crucial for enhancing the catalytic performance of this catalyst.
