Controllable‐Photocorrosion Balance Endows ZnCdS Stable Photocatalytic Hydrogen Evolution
Indexed incrossref
Abstract
Abstract Metal sulfide (MS) photocatalysts are highly attracted for visible‐light photocatalytic hydrogen evolution (PHE), yet the ubiquitous issue of photocorrosion significantly undermines their photostability, often viewed as a detrimental effect. In this study, the positive impact of controllable‐photocorrosion is highlighted on enhancing the PHE activity of MS photocatalysts. Specifically, it establish a clear structure‐activity relationship for ZnCdS solid solutions fabricated via a unique sulfur‐rich butyldithiocarbamic acid solution process. During the PHE process, the sulfur‐rich surface of ZnCdS not only efficiently scavenges excess photogenerated holes but also facilitates the accumulation of sulfur…
