Abstract

This study reports an innovative synthesis method of a Pt/g-C3N4 single atom catalyst for enhancing photocatalytic hydrogen evolution. The method involves the synthesis of free-standing Pt single atoms within an H2PtCl6 ice block using a pulsed laser reduction process, followed by transferring them onto few-layer g-C3N4 through electrostatic adsorption at low temperature. This approach eliminates the need for high-energy lasers and porous support materials during laser solid-phase synthesis. The photocatalytic activities of Pt/g-C3N4 synthesized under various laser conditions are evaluated to optimize the synthesis parameters. The optimal Pt/g-C3N4 catalyst demonstrates a significantly higher photocatalytic hydrogen evolution capability (320 μmol h-1), 129 times that of pure g-C3N4 (2.2 μmol h-1). This work expands the laser-solid phase synthesis method, offering a promising route for the production of single atom catalysts with simple operation, clear synthetic pathways, low cost, and environmental friendliness.
