The development of catalysts with enhanced photocatalytic performance has been receiving growing attention in recent years. The performance of heterostructural catalysts can be dependent on the interface structures of heterostructure. Through a mechanical-chemical pre-reaction, Pt and Au ions are anchored onto red g-C₃N₄ nanosheets to control the in-situ growth of Pt and Au clusters during thermal polymerization process. Electron spin resonance analysis confirms the formation of Z-scheme heterostructure. The Z-scheme heterostructures consisted of Pt/Au clusters and superior thin red/yellow g-C₃N₄ nanosheets are created with enhanced photo-chemical activity. The homogeneous distribution of Pt/Au clusters and the formation of Z-scheme heterostructure are the keys in improving the photocatalytic activities of the material. The estimated H₂, CO, and CH₄ evolution rate of Pt immobilized composites with optimized Pt loading are 5057, 4.82, 1.56 μmol/g/h, respectively. The remarkably enhanced photocatalytic performance of Pt clusters incorporated g-C₃N₄ samples is due to the formation of Z-scheme heterostructures which improves the photogenerated charge carrier transport. Enhancement in photocatalytic activity is also observed for Au clusters embeded g-C₃N₄ nanosheets. The results provide important platforms for exploiting highly efficient catalysts.

近年来，具有增强光催化性能的催化剂的开发受到越来越多的关注。异质结构催化剂的性能取决于异质结构的界面结构。通过机械-化学预反应，Pt 和Au 离子锚定在红色gC ₃ N ₄纳米片上，以控制热聚合过程中Pt 和Au 簇的原位生长。电子自旋共振分析证实了 Z 型异质结构的形成。Z-scheme 异质结构由 Pt/Au 簇和优质薄红色/黄色 gC ₃ N _{4 组成}纳米片具有增强的光化学活性。Pt/Au簇的均匀分布和Z型异质结构的形成是提高材料光催化活性的关键。具有优化的 Pt 负载量的 Pt 固定复合材料的估计 H ₂、CO 和 CH ₄释放速率分别为 5057、4.82、1.56 μmol/g/h。掺入 Pt 簇的 gC ₃ N ₄样品显着增强的光催化性能是由于 Z 型异质结构的形成，这改善了光生载流子传输。还观察到嵌入 gC ₃ N _{4 的}Au 簇的光催化活性增强纳米片。该结果为开发高效催化剂提供了重要平台。
