Abstract
Abstract The sustainable production of hydrogen utilizing solar energy is a pivotal strategy for reducing reliance on fossil fuels. ZnIn 2 S 4 (ZIS), as a typical metal sulfide semiconductor, has received extensive attention in photocatalysis. Although the introduction of sulfur (S) vacancies in ZIS to enhance photocatalytic hydrogen production by creating defect energy levels has been explored, detailed studies on the control and modulation of S‐vacancies in ZIS are sparce. This study demonstrates that while moderate levels of S‐vacancies can enhance hydrogen evolution, excessive vacancies may hinder the process, underscoring the importance of S‐vacancy modulation. Guided by theoretical calculations, We have…
