Abstract:

When incident light energy is greater than or equal to the forbidden bandwidth of a semiconductor, the electrons in its valence band will be excited to the conduction band, and a reduction reaction will occur. This is the basic principle of the photocatalytic reduction of CO2. In this paper, we introduce the reaction mechanism of the photocatalytic reduction of CO2 into C1 products, and we describe the potential applicability of each product.

Key words: Photocatalysis, CO2 reduction, C1 products
