Graphitized carbon nitride (g-C3N4)/tungsten nitride (W2N3) heterostructure was synthesized by high temperature calcination method without using any catalysts and templates. The prepared g-C3N4/W2N3 heterostructure showed an excellent photocatalytic performance under visible light irradiation. The characterization results demonstrated that the W2N3 nanosheets were coated on g-C3N4 nanosheets. The heterostructure of W2N3 and g-C3N4 not only enhanced the absorption capacity of visible light, but also promoted the photocatalytic activity of methyl orange (MO) by separating photogenerated electron hole pairs. The g-C3N4/0.1%W2N3 heterostructure degrades approximately 98% of MO in 1 h. Especially, the g-C3N4/W2N3 heterostructure exhibits a highly stable and reproducible property, indicating that it has potential applications in photocatalysis and other fields.
