Two-in-One Electrons Trapped Fe-BiOCl-Vo Nanosheets for Promoting Photocatalytic-Fenton Degradation Performances of Phenol

Fe-BiOCl-Vo nanosheets with electron-capture centers of doped Fe and surface oxygen vacancies (Vo) for enhanced photocatalytic-Fenton performances were conducted. Compared pristine BiOCl nanosheets, the band gap resulting was narrowed, defective bands introduced due to doping Vo. Furthermore, integrated electron trapping effect Vo can efficiently drive charge transfer separation. As a result, phenol over enhanced. The two-fold four-fold, respectively, as compared photocatalytic nanosheets. During process, multiple reactive species referring holes (h+), superoxide radicals (●O2−), hydroxyl (●OH) induced by separated carriers Fenton reaction played synergetic roles in degradation mineralization. This work provides sophisticated structure design catalysts efficient separation, promoting performance.
