Abstract: CO2 can be converted into syngas via reverse water-gas shift (RWGS) reaction,followed by the F-T reaction to produce CxHy fuels or oxygenated chemicals,which have a significant impact on the environment and the energy structure of the future society and the catalyst plays a key role.The catalyst systems of RWGS reaction are reviewed,especially for the effect of interaction between metal and support,the preparation methods,and the electronic effect of doping elements on RWGS reaction performance of the corresponding catalyst are analyzed.Further,the application of Ce-based catalyst in RWGS reaction was discussed.Optimizing the active component can effectively improve the RWGS reaction performance of the corresponding catalysts for the hydrogenation reduction of CO2 into syngas,and provide a foundation for the industrialization of RWGS reaction.The differences between noble metal and non-noble metal catalysts are also evaluated from points of the preparation methods,reaction conditions,and RWGS reaction performance.The development of novel catalyst material is the key to the industrial application of the RWGS reaction.

Key words: carbon dioxide, catalyst, syngas, reverse water-gas shift reaction, resource utilization

摘要: CO2经逆水煤气变换(RWGS)反应制得合成气(CO和H2),通过费托反应合成CxHy燃料和含氧化学品,将对环境与未来能源结构产生重大影响,且催化剂起着决定性作用。本文概述了RWGS反应催化剂体系研究现状,详细介绍了Pt、Pd、Cu、Ni和Fe基等催化剂的RWGS反应性能,尤其是对金属与载体间的相互作用、制备方法和掺杂元素的电子效应等对相应催化剂的RWGS反应性能进行了分析,进而探讨了Ce基催化剂在RWGS反应中的应用。通过催化剂活性组分的优化能有效地调控相应催化剂的RWGS反应性能,实现CO2有效氢化还原制得合成气,为RWGS反应工业化奠定基础。最后对比总结了贵金属与非贵金属催化剂在制备方法、反应条件及RWGS反应性能间的差异,提出新型催化剂材料开发是RWGS反应工业化应用的关键。
