With the development of shale gas and natural gas,methane has become an abundant resource,and high requirements have been placed on the efficient use of methane or its conversion into chemicals with high added value.The emerging photocatalytic methane conversion,characterized by a high-energy excited state under light irradiation,breaks thermodynamic limits by being powered by clean and sustainable solar energy under mild conditions.This paper further describes the research progress of photocatalytic methane conversion,sums up the design strategy of photocatalyst and finally summarizes and prospects the future of methane photocatalytic conversion.
