Porous ZnIn2S4 with confined sulfur vacancies for highly efficient visible-light-driven photocatalytic H2 production

A porous ZnIn 2 S 4 photocatalyst rich in sulfur vacancies shortens the charge transfer pathway, rapidly capturing the photogenerated electrons, which enhances the separation and migration ability of photoexcited charge carriers, thus enhancing photocatalytic H 2 evolution.
