逆水煤气变换(RWGS)反应是实现CO
2
资源化利用和“双碳”目标的有效途径
,将CO
2
加氢转化为CO是合成高附加值化学品的有效方法。系统综述了RWGS反应机理、催化剂研究进展及其在反应过程中的动态结构演变。反应机理主要包括氧化-还原机理和缔合反应机理,其主导路径受催化剂组成与反应条件调控。在催化剂方面,贵金属(如Pt、Au)、非贵金属(如Cu、Ni和Fe)及过渡金属碳化物(如Mo
2
C)均展现出良好的RWGS反应催化性能,其中金属-载体相互作用、助剂修饰及界面结构调控是提升催化活性的关键策略。在高温及复杂反应气氛中,催化剂常发生动态结构演变,如晶相转变、渗碳和元素迁移等,影响着催化剂的真实活性位点与催化活性。通过探究RWGS反应催化剂动态结构演变,可为其他反应(如烷烃脱氢反应)的催化剂设计提供有效策略。最后总结了目前RWGS反应催化剂面临的挑战并提出了未来发展的方向。
The reverse water-gas shift (RWGS) reaction is as an effective approach to achieving CO
2
resource utilization and the “dual carbon” goals
and CO
2
hydrogenation to produce CO serves as a viable method for synthesizing high-value chemicals. The RWGS reaction mechanisms
research progress on catalysts and their dynamic structural evolution during the reaction were systematically summarized. Reaction mechanisms primarily include the redox mechanism and the associative mechanism
and its dominant pathway is regulated by catalyst compositions and reaction conditions. In terms of catalysts
noble metals (such as Pt and Au)
non-noble metals (such as Cu
Ni and Fe) and transition metal carbides (such as Mo
2
C) exhibit excellent catalytic performances. Among these
metal-support interactions
promoter modification
and interfacial structure regulation are key strategies for enhancing catalytic activities. Under high temperatures and complex atmospheres
catalysts often undergo dynamic structural evolution
such as phase transformation
carburization and elemental migration. These changes profoundly influence the real active sites and catalytic activities of the catalysts. By exploring the dynamic structural evolution of catalysts for RWGS reaction
effective strategies can be provided for designing catalysts for other reactions
such as alkane dehydrogenation reactions. Finally
the current challenges of the catalysts for RWGS reaction were summarized
and future research directions were proposed.
