Fabrication of g-C3N4/Bi2WO6 as a direct Z-scheme excellent photocatalyst

To improve the photocatalytic efficiency of Bi 2 WO 6 , two types of g-C 3 N 4 nanomaterial, g-C 3 N 4 quantum dots and nanosheets, were incorporated with Bi 2 WO 6 to construct two kinds of g-C 3 N 4 /Bi 2 WO 6 photocatalysts with excellent photocatalytic activity.
