【 摘 要 】

From the current global energy consumption distribution, traditional fossil fuels still occupy a dominant position, and their share will remain high for some time to come. However, limited non-renewable traditional resources cannot always be used by humans. When they are finally consumed, the consumption of traditional fossil fuels such as oil, natural gas, coal, etc. will generate a lot of greenhouse gases, and the massive emissions of CO2 will cause a series of unfavorable chain reactions. Photocatalytic reduction of CO2 as a hydrocarbon fuel not only reduces the CO2 content in the atmosphere, but also solves the environmental problems brought about by the greenhouse effect, and can provide energy fuel with considerable economic effects. The research progress of photocatalytic reduction of CO2 is reviewed. Some common TiO2-based photocatalytic materials are introduced, and the characteristics of various materials are compared. Finally, the research on TiO2-based photocatalytic materials is prospected.
