本文综述了近年来关于助剂改性对贵金属催化剂活性中心的构建及其一氧化碳PROX反应催化性能影响的最新研究进展,详尽地比较了碱(土)金属、过渡金属以及稀土氧化物对Au催化剂和Pt催化剂的影响。此外,还对CO氧化反应的机理、负载型贵金属催化剂在不同反应过程和存储条件下的失活原因进行了讨论。最后,提出了一些尚未解决或者仍需进一步研究的问题,并展望了CO选择氧化催化剂的研究和发展方向。
This review summarizes the latest research progress on the construction of active sites of noble metal catalysts and the catalytic performance of their COX PROX reactions in recent years. The effects of alkali (earth) metals, transition metals and rare earth oxides on the catalytic performance of Au catalysts and Effect of Pt catalyst. In addition, the mechanism of CO oxidation reaction, the reason of deactivation of supported precious metal catalysts under different reaction conditions and storage conditions are also discussed. Finally, some problems that have not yet been solved or still need to be further studied are proposed, and the research and development of CO selective oxidation catalysts are also prospected.
