Developing ideal photocatalysts for energy regeneration and environmental remediation by combining the advantages of individual semiconductors remains a significant challenge. Herein, tungsten trioxide (WO3)/Cu3SnS4 S-scheme heterojunction composite are developed. Initially, doped oxygen vacancy (OV) was prepared on two-dimensional WO3 nanosheets direct calcination method. Subsequently, Cu3SnS4 nanoflowers produced via one-step hydrothermal process, which then used to wrap nanosheets. The close contact between Cu3SnS4, coupled with unsaturated C–OV coordination, enhanced interfacial electron transport. Under visible light irradiation, WO3/Cu3SnS4 shows an impressive H2 production rate 3345.26 μmol h–1 g–1, improvement over performances Cu3SnS4. Moreover, demonstrated highest photocatalytic tetracycline degradation efficiency, achieving 99.4% within 90 min illumination. An efficient system well-aligned band structure successfully constructed. This design effectively extends their lifetime, allowing achieve maximum efficiency in reaction.

Abstract In recent years, research on photocatalytic reduction of carbon dioxide has aroused widespread heated discussions, combined with the current theme energy conservation and emission reduction. Photo-reduction is considered to be an important technology promising applications. At present, photo-reduced mainly limited by difficulty absorbing visible light short lifetime photogenerated carriers. Therefore, we designed synthesized bismuth ball-supported g-C 3 N 4 . Bismuth a non-precious metal but at same time SPR (Surface Plasmon Resonance) precious metals. The effect was used increase absorption extend carriers different loads. CN-Bi0.7 exhibited superior CO2 activity CO evolution 8.2805 μmol·g −1 ·h , which 4-fold times higher than that .The enhanced 2 conversion efficiency can attributed Bi spheres synergetic effects
