摘　　要：光热催化还原CO_(2)作为符合国家“双碳”政策的减碳技术,将温室气体CO_(2)转化为重要的化学燃料和工业原料有望促进“双碳”目标早日实现。光热催化还原CO_(2)利用表面等离子体共振将光能转化为热能,或通过将光能和热能耦合,从而提高太阳光利用率,来催化CO_(2)在较为温和的条件下高效转化为碳氢燃料或工业原料,因而受到碳捕获与转化领域研究人员的高度关注。对目前光热催化还原CO_(2)的研究进展进行了综述,介绍了设计用于CO_(2)转化反应的光热催化剂的最新进展,包括CO_(2)加氢生成CO、CH_(4)、CH_(3)OH或C^(2+)、CH_(4)的CO_(2)重整(CRM)、CO_(2)环加成反应等,最后分析了现阶段光热催化还原CO_(2)催化剂的制约因素,并对其发展前景以及面临的挑战进行了展望。As a carbon reduction technology in line with the national“double carbon”policy,the photothermal catalytic reduction of CO_(2) is expected to contribute to the early realization of the“double carbon”goal by converting CO_(2),a greenhouse gas,into important chemical fuel and industrial raw materials.Photothermal catalytic reduction of CO_(2) is of great interest to researchers in the field of carbon capture and conversion because it uses surface plasmon resonance to convert light energy into heat energy,or couples light and heat energy to improve the utilization of sunlight to catalyze the efficient conversion of CO_(2) into hydrocarbon fuels or industrial feedstocks under relatively mild conditions.This paper reviewed the current research progress of photothermal catalytic reduction of CO2,introduced the latest progress of photothermal catalysts designed for CO_(2) conversion reactions,including CO_(2) hydrogenation to CO,CH_(4),CH_(3)OH or C^(2+),CO_(2) reforming(CRM)of CH4,and CO_(2) cycloaddition reactions,etc.Finally,it analyzed the constraints of photothermal catalytic CO_(2) reduction catalysts at the present stage,and gave an outlook on their development prospects and challenges they faced.
