摘要
基于光热催化在CO_(2)还原及制备碳氢燃料方面的优势,重点介绍了光热催化分类中的光致热催化还原CO_(2)反应,包括其反应机理、近期进展、应用及催化剂分类。同时,从强化光反应、热反应、表面反应不同方面对光致热催化还原CO_(2)反应的性能提升策略进行了归纳分析。该反应可将CO_(2)和H_(2)O催化生成C1、C2产物,光照下催化剂表面局部温度的升高有利于增强光致热催化CO_(2)还原反应速率。最后,对该方向存在的问题进行了深入分析,提出了未来主要研究方向的建议。
Based on the advantages of photothermal catalysis in reducing CO_(2)to valuable fuels using solar and/or thermal driven catalysts,the mechanism,latest research,application and catalyst types are mainly discussed.At the same time,different strategies to improve the catalytic performance are concluded from three aspects:strengthening photoreaction,thermal reaction and surface reaction.It is analyzed that the local surface temperature of catalyst under illumination is the key factor affecting the rate of CO_(2)reduction reaction.The catalytic reaction can produce C1 and C2 products from CO_(2)and H_(2)O.The rate of the reaction increases with the local temperature on the surface of the catalyst under light.Finally,the existing problems are analyzed in depth and the speculations on the future research priorities are prospected.
