The photocatalytic properties of metal-containing nanocomposites based on crystalline graphite-like carbon nitride (CGCN), synthesized in situ by photoreduction of palladium, platinum, and gold ions in the reaction of hydrogen evolution from 96% ethanol under the action of visible light, were determined. The H₂ formation rate increases in the sequence of CGCN/Au(1%) < CGCN Pd(0.4%) < CGCN/Pt(0.5%) at the optimal metal content in the composite. The efficiency of hydrogen evolution increases significantly even at half the metal content in the presence of HCl additives. The effective quantum yield of H₂ formation is ~54% at 405 nm for the most active CGCN/Pt composite (0.25%).

通过钯、铂和金离子在可见光作用下从 96% 乙醇析氢反应原位合成的基于结晶石墨状氮化碳 (CGCN) 的含金属纳米复合材料的光催化性能，被确定。在复合材料中最佳金属含量下，H ₂形成率以CGCN/Au(1%) < CGCN Pd(0.4%) < CGCN/Pt(0.5%) 的顺序增加。即使在 HCl 添加剂的存在下，即使金属含量减半，析氢效率也显着提高。对于最活跃的 CGCN/Pt 复合材料 (0.25%) ，H ₂形成的有效量子产率在 405 nm 处约为 54%。
