摘要：

The Fe-doped two-dimensional BiOCl nanosheets with rich surface oxygen vacancies (Fe-BiOCl OVs) were prepared by a solvothermal method, which could completely degraded phenol solution (20 ppm) under the photocatalytic-Fenton synergistic effect. The surface oxygen vacancies play an important role in enhancing the synergistic degradation activity, which can not only effectively promote the separation efficiency of photogenerated charges and speed up the Fenton reaction, but also act as the activation sites of H2O2 to generate hydroxyl radicals (.OH), all of these have a positive effect on the synergistic degradation system.
