Methanol synthesis from CO2 under atmospheric pressure over supported Pd catalysts

Pd/ZnO catalyst exhibits high activity and selectivity for methanol synthesis in the hydrogenation of CO2 under atmospheric pressure. PdZn alloys are formed upon reduction of the Pd/ZnO catalyst at high temperatures. The catalytic activity and selectivity are greatly enhanced upon the formation of such PdZn alloys. The turnover frequency and selectivity of methanol formation are markedly larger than those of a Cu/ZnO type control catalyst.
