ABSTRACT = {Photocatalytic synthesis of hydrogen peroxide offers an effective solution to the energy 
crisis. The design and development of high-activity and low-cost photocatalysts are crucial 
for H<sub>2</sub>O<sub>2</sub> production. In this work, Zn<sub>0.4</sub>Cd<sub>0.6</sub>S with abundant S vacancies (S<sub>V</sub>-ZCS) is 
developed for H<sub>2</sub>O<sub>2</sub> photosynthesis under 405 nm LED illumination without additional 
cocatalysts. The S vacancies serve as photo-generated electron trap centers, effectively 
extending the lifetimes of photogenerated carriers and promoting the separation of 
photoelectric carriers. Additionally, S<sub>V</sub>-ZCS is endowed with enhanced light capture 
capability, enhancing the overall photocatalytic activity for H<sub>2</sub>O<sub>2</sub> production. The results 
were in line with expectations, the S<sub>V</sub>-ZCS samples demonstrated a hydrogen peroxide 
(H<sub>2</sub>O<sub>2</sub>) productivity of 3902 μmol L<sup>-1</sup> h<sup>-1</sup>
 when subjected to visible light irradiation, 
representing a significant increase compared to that of ZCS (2840 μmol L<sup>-1</sup> 
h<sup>-1</sup>
). This work 
provides an effective strategy for preparing photocatalysts for efficient hydrogen peroxide 
production. },
