Air‐condition process for scalable fabrication of CdS/ZnS 1D/2D heterojunctions toward efficient and stable photocatalytic hydrogen production

Abstract We report the scalable fabrication of CdS/ZnS 1D/2D heterojunctions under ambient air conditions (i.e., room temperature and atmospheric pressure) in which ZnS nanoparticles are anchored on surface CdS nanosheets. The as‐formed exhibit a significantly enhanced photocatalytic H 2 evolution rate 14.02 mmol h −1 g when irradiated with visible light, is ~10 85 times higher than those pristine nanosheets nanoparticles, respectively, superior to most CdS‐based photocatalysts reported date. Furthermore, they provide robust performance demonstratable stability over 58 h, indicating their potential for practical applications. formation not only provides improved exposed active sites that respond illumination but also rapid pathway generate photogenerated carriers efficient separation transfer through matrix single‐crystalline In addition, first‐principles simulations demonstrate existence rich Zn vacancies increases energy level valence band maximum construct type‐II Z‐scheme mixed heterojunctions, plays critical role suppressing recombination limited photocorrosion enhance behavior.
