Photothermal catalysis in CO2 reduction reaction: Principles, materials and applications

Reducing CO2 emission has become one of the most urgent issues in the world. The use of abundant solar energy to convert carbon dioxide into carbon-based chemicals would be a tremendous advance. There are many papers on photocatalysis or thermal catalysis in the reduction of CO2, however, there is little research on photothermal catalysis for this purpose. We summarize our current knowledge of this topic, and the classification of catalysts (new carbon materials, oxide materials, metal sulfide materials, MOF materials, layered double hydroxide materials), their modification and their use in the reduction of CO2 is discussed. Trends in the development of new catalysts are considered.

Automated summary

Reducing CO2 emission is urgent, and utilizing solar energy to convert CO2 into carbon-based chemicals is a significant advancement. Current research mostly focuses on photocatalysis or thermal catalysis, with limited exploration in photothermal catalysis. This article provides a comprehensive overview on catalyst classification (new carbon materials, oxide materials, metal sulfide materials, MOF materials, layered double hydroxide materials), their modification, and their application in CO2 reduction. The study also examines trends in developing new catalysts for this purpose.
