Abstract:
Reducing CO
2 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 CO
2, 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 CO
2 is discussed. Trends in the development of new catalysts are considered.
