Summary: | •WO3/g-C3N4 was prepared by dispersing WO3 nanosheets on g-C3N4 nanosheets.•The O2− played key role in the photocatalytic oxidation process were clearly identified.•The concentration of O2− quantificationally determined by NBT probing method.
WO3 nanosheets and its hybridized nanocomposite, WO3/g-C3N4, were prepared by a simple direct precipitation method. The as-prepared WO3/g-C3N4 showed enhanced photocatalytic activity toward degrading methyl orange (MO). The O2−, which played key role in the photocatalytic oxidation process, were clearly identified and quantificationally determined by the trapping experiment and nitroblue tetrazolium (NBT) probing method. Z-scheme photocatalytic mechanism was proposed accordingly. |
