Abstract

The ternary SnS2/SnO2/rGO nanocomposites were successfully designed and fabrication for promoting the separation and transfer of photogenerated electrons. Based on the introduction of rGO, adjusting the content of SnS2 can tune the energy of the conduction band to a suitable position, which can promote the activity and selectivity for photocatalytic reduction of CO2. The internal mechanism of the energy band structure that determines the separation and transport of photogenerated electrons was further studied to establish the relationship between the energy band and the photocatalytic performance of activity and selectivity. This work provides some references for the field of photocatalytic decarburization.
