摘　　要：为实现“双碳”目标以及缓解环境污染问题,CO_(2)利用成为了当前研究的热点之一。由于受到CO_(2)分子结构以及复杂的加氢路线限制,开发高活性、高选择性的催化剂是CO_(2)高值化利用的关键。负载型金属催化剂因具有大比表面积和高分散度等优势,在CO_(2)加氢制CH_(4)/CO反应中应用广泛。为提高催化剂的催化活性和产物选择性,需要了解负载型金属催化剂在CO_(2)加氢制CH_(4)/CO反应过程中的界面调控作用。其中,影响界面结构的因素包括金属结构、载体性质和金属-载体相互作用,这些因素共同决定了催化剂催化性能。总结了CO_(2)加氢制CH_(4)/CO反应的热力学和机理,重点综述了负载型金属催化剂的研究进展,并讨论了负载型金属催化剂在CO_(2)加氢制CH_(4)/CO反应中的界面调控作用和催化剂未来的发展方向。To achieve the goal of“dual carbon”and alleviate environmental pollution,utilization of CO_(2) has become a focal point in current research.Due to the limitations of CO_(2) molecular structure and the complexity of hydrogenation routes,the development of highly active and selective catalysts is crucial for achieving high-value utilization of CO_(2).Supported metal catalysts are widely used in CO_(2) hydrogenation to CH_(4)/CO reaction due to the advantages of large specific surface area and high dispersion.To enhance the catalytic activity and product selectivity of catalysts,it is essential to understand the role of interfacial modulation in supported metal catalysts during CO_(2) hydrogenation to CH_(4)/CO reaction.The interfacial structure is influenced by metal structures,carrier properties and metal-carrier interactions,which determine the catalytic performance of catalysts.The thermodynamics and reaction mechanisms of CO_(2) hydrogenation to CH_(4)/CO were summarized,with a focus on the research progress on supported metal catalysts.The interfacial modulation and future development direction of supported metal catalysts for CO_(2) hydrogenation to CH_(4)/CO were discussed.
