Photocatalytic CO 2 Reduction

Photocatalytic conversion of CO 2 into valuable chemicals and fuels has been considered as one of the most promising strategies to simultaneously prevent global warming and store renewable energy. To improve the photocatalytic CO 2 reduction efficiency and realize the ultimate objective of this technology for practical application, the development of highly efficient and long-term durability photocatalysts is of great importance. In this chapter, on the basis of the photocatalytic CO 2 conversion mechanism analysis, we summarize the effective method to boost the photocatalytic CO 2 reduction activities, including defect engineering, loading of metal co-catalyst, and construction of heterojunctions. We hope this chapter could provide some inspirations for design and fabrication of high-performance photocatalysts for CO 2 conversion.
