  • Description: Fe-BiOCl-V[sub.o] nanosheets with electron-capture centers of doped Fe and surface oxygen vacancies (V[sub.o]) for enhanced photocatalytic-Fenton performances were conducted. Compared with pristine BiOCl nanosheets, the band gap of the resulting Fe-BiOCl-V[sub.o] nanosheets was narrowed, and defective bands were introduced due to the Fe doping and V[sub.o]. Furthermore, the integrated electron trapping effect of V[sub.o] and doped Fe can efficiently drive charge transfer and separation. As a result, the photocatalytic-Fenton performances of phenol over Fe-BiOCl-V[sub.o] nanosheets were enhanced. The photocatalytic-Fenton performances of Fe-BiOCl-V[sub.o] nanosheets were enhanced two-fold and four-fold, respectively, as compared with the photocatalytic performances of Fe-BiOCl-V[sub.o] and pristine BiOCl nanosheets. During the photocatalytic-Fenton process, the multiple reactive species referring holes (h[sup.+]), superoxide radicals (●O[sub.2] [sup.−]), and hydroxyl radicals (●OH) induced by the efficiently separated charge carriers and Fenton reaction played synergetic roles in phenol degradation and mineralization. This work provides a sophisticated structure design of catalysts for efficient charge transfer and separation, promoting photocatalytic-Fenton performance.
