摘要

加氢制高附加值含碳化合物是实现碳资源循环利用的关键路径，其中逆水煤气变换（RWGS）反应是重要的中间步骤，对促进CO

资源深度利用具有重要意义。热力学分析表明，高温有利于RWGS反应，但高温环境对催化剂的稳定性提出了严苛要求。近年来，尖晶石催化剂因具有高热稳定性、活性点位可设计以及制备工艺简单等优点在RWGS反应中展现出良好应用前景。综述了面向RWGS反应的尖晶石催化剂（Cu基尖晶石和其他金属尖晶石催化剂）研究进展，分析了尖晶石催化剂构效关系，主要包括金属阳离子、表面氧空位和碱性位点等对催化行为的影响机制，提出了RWGS反应机理，展望了该领域亟需解决的关键问题。分析表明，活性金属与氧空位对H

和CO

的活化起到主要作用，催化剂碱性位点对促进CO

吸附与活化也有重要贡献，尖晶石晶面结构对CO

和CO吸附表现出偏好性和定向调控性。尖晶石催化剂催化RWGS反应机理为氧化还原机理与中间体机理，Cu-Al尖晶石催化剂主要遵循中间体机理，其他尖晶石催化剂如AFe

（A = Ni、Cu或Zn）和ZnCr

遵循氧化还原机理。

Abstract

The synthesis of high-value-added carbon compounds via CO

hydrogenation is recognized as a critical pathway for achieving carbon resource recycling

in which the reverse water gas s

hift (RWGS) reaction serves as an essential intermediate step

playing a significant role in promoting the deep utilization of CO

resources. Thermodynamic analysis indicates that high temperatures are favorable for the RWGS reaction

whereas high-temperature imposes stringent requirements on catalyst stability. In recent years

spinel catalysts have shown promising potential in the RWGS reaction due to their high thermal stability

tunable active sites and simple preparation processes. The research progress on spinel catalysts (Cu-based and other metal spinel catalysts) for RWGS reaction was summarized. The structure-activity relationships of spinel catalysts were analyzed

mainly including the influence mechanisms of metal cations

surface oxygen vacancies and basic sites on catalytic behaviors. The RWGS reaction mechanisms were proposed

and the key issues that urgently need to be addressed in this field were discussed. It is demonstrated that the activation of H

and CO

is mainly facilitated by active metals and oxygen vacancies. CO

adsorption and activation are also promoted by basic sites. In addition

the spinel crystal structure exhibits preference and directional regulation for CO

and CO adsorption. The RWGS reaction mechanisms catalyzed by spinel catalysts are redox mechanism and the associative mechanism. Cu-Al spinel catalysts mainly follow the associative mechanism

while other spinel catalysts such as AFe

(A = Ni

Cu or Zn) and ZnCr

spinel catalysts follow the redox mechanism.
