AgBr Nanoparticles Anchored on CdS Nanorods as Photocatalysts for H2 Evolution
Source abstract
Abstract
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.
