Abstract:

Solar-driven conversion of CO2 and CH4 to syngas is a very promising technology for producing renewable fuels. However, solar-driven CH4 reforming catalysts suffer from low conversion efficiency, fast photogenerated electron-hole complexation rate and poor catalyst stability. This paper briefly describes the possible mechanisms of photocatalytic CO2 and CH4 reforming, including the adsorption of CO2 and CH4, the migration of photogenerated electrons and holes and the desorption of products. The research progress of precious metal catalysts, non-precious metal catalysts and carbon-nitrogen compounds for the photocatalytic CO2 and CH4 reforming is highlighted, and the advantages and shortcomings of these catalysts are also summarized. Finally, this paper discusses the possible development directions in the field of photocatalytic conversion of CO2 and CH4 to syngas, i.e. the development and design of efficient photocatalysts to improve the reaction efficiency, catalytic mechanism investigation by density functional theory (DFT) and advanced characterization techniques.

摘要:

太阳能驱动的CO2与CH4转化为合成气是一种非常有前景的生产可再生燃料的技术,然而太阳能驱动的CH4重整催化剂存在转化效率低、光生电子与空穴复合速率快及催化剂稳定性差等问题。本文简述了光催化CO2与CH4重整的可能机理,包括CO2和CH4的吸附、光生电子与空穴的迁移及产物的脱附过程。重点介绍了光催化CO2和CH4重整过程中贵金属催化剂、非贵金属催化剂及碳氮化合物等催化剂的研究进展,并总结归纳了各类催化剂的优点与不足。最后,本文探讨了光催化转化CO2与CH4制合成气研究领域未来可能的发展方向:开发设计高效的光催化剂提高反应效率;通过密度泛函理论计算及高端表征技术探究催化机理。
