But g-C for the synthesis of the complexes3N4Is obtained by calcining melamine by a traditional method, has no larger specific surface area, and limits the further improvement of the catalytic activity of the melamine. Shijing Liang et al co-doped g-C with Au and Pt3N4To improve the performance of hydrogen production by photolysis of water and to investigate the performance of hydrogen production by photolysis of water by loading different metals [ Liang S, Xia Y, Zhu S, et al Au and Pt co-loaded g-C3N4nanosheetsfor enhanced photocatalytic hydrogen production under visible lightirradiation[J]. Applied Surface Science, 2015, 358:304-312.]. But in the preparation of Au/Pt/g-C3N4For nanocomposites, ordinary g-C is used3N4The catalyst has low catalytic activity, the preparation process is complex when Au and Pt are loaded simultaneously, and the cost is greatly improved while the performance of hydrogen production by photolysis is improved by loading two noble metals.
