Abstract Copper-based catalysts with different metal-oxide(s) composition were synthesized and applied in CO2 hydrogenation to methanol. The metal component(s) (Cu, Zn and/or Mn) were dispersed on high surface area SBA-15. Correlations between the adsorption properties of catalysts and the catalytic performances reveal that a catalyst with both strong hydrogenation strength and moderate CO2 adsorption strength is crucial for achieving high CO2 conversion. Additionally, the availability of metal-oxide(s) interfacial area greatly enhances methanol selectivity. An adequate balance between H2 and CO2 adsorptions as well as metal-oxide(s) interfacial area were responsible for the high catalytic activity achieved in this study.

二氧化碳在多功能催化剂上加氢制甲醇：反应物吸附和金属氧化物界面面积的影响

摘要 合成了不同金属氧化物组成的铜基催化剂，并将其应用于CO2加氢制甲醇。金属成分（Cu、Zn 和/或 Mn）分散在高表面积 SBA-15 上。催化剂吸附性能与催化性能之间的相关性表明，具有强加氢强度和中等 CO2 吸附强度的催化剂对于实现高 CO2 转化率至关重要。此外，金属氧化物界面面积的可用性大大提高了甲醇的选择性。H2 和 CO2 吸附以及金属氧化物界面面积之间的充分平衡是本研究中实现高催化活性的原因。
