AI Technical Summary
When BiOCl and Bi2WO6 are used as photocatalytic materials, the separation efficiency of photogenerated carriers is low and the photogenerated electrons and holes are easy to recombine, resulting in low degradation activity. The existing technology of combining Bi2WO6 and BiOCl has failed to effectively improve the binding tightness, thus limiting its photocatalytic performance.
By in-situ composite of Bi2WO6 onto pre-synthesized BiOCl, a two-step solvothermal method was used to prepare Bi2WO6/BiOCl composite photocatalysts, forming a stable composite structure in which Bi2WO6 microspheres are coated on BiOCl microspheres, thereby enhancing the tightness of their bonding.
The photocatalytic performance of the Bi2WO6/BiOCl heterojunction was improved, enabling the effective degradation of 20 mg/L TNT wastewater under visible light. It exhibited excellent photocatalytic performance and stability, and significantly improved the degradation efficiency.
