A novel graphene-like BN modified BiPO material was prepared for the first time via a simple solvothermal process with the assistance of reactable ionic liquid 1-decyl-3-methylimidazolium dihydrogen phosphate ([Omim]HPO). The as-prepared photocatalyst was characterized by XRD, FT-IR, Raman, XPS, TEM, DRS, BET, PL, EIS and ESR to investigate the structure, morphology, optical property, surface area, electrical property and active species. The photocatalytic activities of graphene-like BN/BiPO materials were evaluated by the degradation of antibiotic enrofloxacin (ENR) under UV light irradiation and the 1wt% graphene-like BN/BiPO displayed the best activity among the BN/BiPO composites. The enhanced photocatalytic activity for the removal of enrofloxacin was attributed to higher separation efficiency of photogenerated electron-hole pairs, and the generated more O and OH radicals when the BN was modified on BiPO. Moreover, a probable degradation mechanism was proposed for the improved photocatalytic activity of BN modified BiPO.
一种新型的类石墨烯 BN 修饰的 BiPO 材料首次通过简单的溶剂热法在可反应的离子液体 1-癸基-3-甲基咪唑二氢磷酸盐([Omim]HPO)的协助下制备。所制备的光催化剂通过 XRD、FT-IR、拉曼、XPS、TEM、DRS、BET、PL、EIS 和 ESR 进行了结构、形态、光学性质、表面积、电学性质和活性物种的表征。通过在 UV 光照射下对抗生素恩诺沙星（ENR）的降解评价了类石墨烯 BN/BiPO 材料的光催化活性，在 BN/BiPO 复合材料中，1wt%的类石墨烯 BN/BiPO 显示出最佳的活性。BN 修饰 BiPO 去除恩诺沙星的光催化活性增强归因于光生电子-空穴对的分离效率更高，并且当 BN 修饰 BiPO 时会产生更多的 O 和 OH 自由基。此外，提出了一种可能的降解机制，以解释 BN 修饰 BiPO 光催化活性的提高。
