Abstract Enhancing photocatalytic activity by changing the electronic structure of catalyst is an effective strategy. 2H‐MoS 2 has semiconductor properties, and its unsaturated side S atom main active site for activity. However, due to weak S─H bond energy, hydrogen adsorption capacity weak. In this work, MoS adjusted S‐rich treatment, resulting in formation Mo vacancy (MoS ‐V ). The level vacancies was assessed using UV–vis diffuse reflectance spectroscopy (UV–vis DRS). As these can capture certain photogenerated electrons, thereby reducing recombination electron‐hole pairs. Through DFT calculation, it found that antibonding orbital electron filling weakened, energy S─Mo between enhanced, which more conducive proton adsorption. evolution ‐3, underwent optimal achieved a remarkable rate 2404.6 µmol g −1 h dye eosin Y (EY) sensitization system, significantly surpassing lacking S‐enriched treatment. This study introduces novel concept enhancing performance metal sulfides via defect engineering.
