Interfacial engineering of Cd0.5Zn0.5S/BiOBr S-scheme heterojunction with oxygen vacancies for effective photocatalytic antibiotic removal

The construction of S-scheme heterojunction photocatalysts has emerged as a promising strategy to address the urgent need for efficient antibiotic wastewater remediation. However, persistent challenges in achieving interfacial intimacy and precise charge transfer regulation between semiconductors have hindered their practical implementation. In this work, we engineered a hierarchical Cd 0.5 Zn 0.5 S/BiOBr S-scheme heterojunction via a controlled solvothermal synthesis, where BiOBr microspheres serve as the core, and Cd 0.5 Zn 0.5 S nanoparticles form a conformal shell. This architecture ensures maximal interfacial contact and directional charge dynamics, critical for optimizing photocatalytic efficiency. The…
