The chemical transformation of CO not only mitigates the anthropogenic CO emission into the Earth's atmosphere but also produces carbon compounds that can be used as precursors for the production of chemicals and fuels. The activation and conversion of CO can be achieved on multifunctional catalytic sites available at the metal/oxide interface by taking advantage of the synergy between the metal nanoparticles and oxide support. Herein, we look at the recent progress in mechanistic studies of CO hydrogenation to C1 (CO, CHOH, and CH) compounds on metal/oxide catalysts. On this basis, we are able to provide a better understanding of the complex reaction network, grasp the capability of manipulating structure and combination of metal and oxide at the interface in tuning selectivity, and identify the key descriptors to control the activity and, in particular, the selectivity of catalysts. Finally, we also discuss challenges and future research opportunities for tuning the selective conversion of CO on metal/oxide catalysts.
CO 的化学转化不仅可以减轻人为 CO 排放到地球大气中，还可以产生可作为化学物质和燃料前体的碳化合物。通过利用金属纳米粒子和氧化物载体之间的协同作用，可以在金属/氧化物界面上的多功能催化位点上实现 CO 的活化和转化。在此，我们着眼于金属/氧化物催化剂上 CO 加氢转化为 C1（CO、CHOH 和 CH）化合物的反应机理研究的最新进展。在此基础上，我们能够更好地理解复杂的反应网络，掌握在界面上操纵金属和氧化物的结构和组合以调节选择性的能力，并确定控制催化剂活性，特别是选择性的关键描述符。最后，我们还讨论了在金属/氧化物催化剂上调节 CO 选择性转化的挑战和未来研究机会。
