We designed and fabricated an AgBr/CdS S-scheme heterojunction with Ag–S bonds. It was found that the formed Ag–S bond served as a bridge to transfer photoinduced electrons from CdS to AgBr. The as-prepared AgBr/CdS materials showed remarkably enhanced performance and good stability for photocatalytic hydrogen evolution using triethanolamine (TEOA) as the sacrificial agent. Under visible light illumination, the 10% AgBr/CdS sample exhibited optimal activity (5406 μmol h^–1 g^–1) among all samples, which was 85 times higher than that of the pristine CdS (64 μmol h^–1 g^–1). Because of the formation of the AgBr/CdS S-scheme heterojunction and the rapid electron-transfer channel provided by Ag–S bonds, high charge separation and utilization efficiency were achieved, which contributed to its superior performance.

AgBr 纳米粒子锚定在 CdS 纳米棒上作为 H2 析出的光催化剂

我们设计并制造了具有 Ag-S 键的 AgBr/CdS S 型异质结。发现形成的 Ag-S 键充当了将光生电子从 CdS 转移到 AgBr 的桥梁。所制备的 AgBr/CdS 材料在使用三乙醇胺 (TEOA) 作为牺牲剂的光催化析氢方面表现出显着增强的性能和良好的稳定性。在可见光照射下，10% AgBr/CdS 样品在所有样品中表现出最佳活性（5406 μmol h ^–1 g ^–1），比原始 CdS（64 μmol h ^–1 g ^–1）。由于AgBr/CdS S型异质结的形成和Ag-S键提供的快速电子转移通道，实现了高电荷分离和利用效率，这有助于其优越的性能。
