Using expandable graphite as raw material, graphite flakes were obtained through high-temperature expansion and mechanical sanding. Graphite flakes were used as templates to synthesize silicon carbide nanosheets (SiCNSs) with different specific surface areas. The effect of specific surface area on the photocatalytic hydrogen production performance of SiCNSs was explored. The results show that the specific surface area of SiCNSs has a significant impact on its hydrogen production performance, and increasing the specific surface area of the photocatalyst is beneficial to enhance its hydrogen production activity. The maximum specific surface area of SiCNSs can reach 149 m²·g^-1, and its photolysis water hydrogen evolution rate was 51.0 μL·g^-1·h^-1. Based on the analysis of the structure and morphology of graphite flakes and SiCNSs, the formation mechanism of in situ generation of SiCNSs using graphite flakes as a template is proposed. The process mainly follows the gas-solid reaction mechanism. At high temperatures, gaseous SiO and Si react with graphite flakes to form SiCNSs, and the product better inherits the flake structure of graphite flakes. After removing carbon from the unreacted part of the large-size graphite sheet, a large number of nano-sized perforations were left, so that the specific surface area of the produced silicon carbide was higher than that of the small-size graphite sheet.
