摘要：

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 O-center dot(2), 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. (C) 2018 Elsevier B.V. All rights reserved.
