WO _{3− <i>x</i>} /S‐Doped g‐C ₃ N ₄ Step‐Scheme Heterojunction for High‐Efficiency and Stable Vis–NIR Photocatalytic Removal of Pharmaceuticals and Personal Care Products

Pharmaceuticals and personal care products (PPCPs) have attracted widespread attention due to their durability the environment. Therefore, it is highly desirable develop new technologies that are environmentally friendly, energy saving, compatible degrade these pollutants. In this study, a vis–NIR-driven efficient S-scheme photocatalyst, WO3−x /S doped g-C3N4, used for PPCPs degradation. The results show photocatalytic activity of g-C3N4 composite system much higher than g-C3N4. introduced has great positive effect on performance photocatalyst both naproxen diclofenac. Due fast photogenerated carrier separation brought by S-scheme, /S-doped nanocomposite exhibits enhanced in degradation rate 99.2%, diclofenac can also be as high 99.5%. This research important reference value synthesis WO3-based photocatalysts environmental applications.
