| Abstract: | Oxygen defects are introduced into BiOI by a simple glycerol treatment. This deficient BiOI demonstrated 3.5 times higher photocatalytic performance than the untreated BiOI nanosheets for methyl orange (MO) degradation under visible light irradiation. Moreover, the deficient BiOI nanosheets have excellent cycling stability. The improved efficiency can be ascribed to the significantly enhanced separation efficiency of photogenerated and utilized more solar light. |
