Abstract
The novel α-SnWO4/g-C3N4 composites have been successfully synthesized by a facile hydrothermal method. The crystalline structure, physicochemical property and morphology of the as-prepared samples were characterized by XRD, SEM, TEM, UV–vis and PL. Compared to the pristine α-SnWO4 and g-C3N4, the α-SnWO4/g-C3N4 heterostructure exhibited enhanced photocatalytic activity toward the degradation of Rhodamine B (RhB) under visible light irradiation, which can be attributed to the effective electrons/holes transfer and separation, due to the heterojunction formed between α-SnWO4 and g-C3N4. Moreover, the α-SnWO4/g-C3N4 demonstrated good recyclability properties which were beneficial for its practical application. The photocatalytic mechanism of the α-SnWO4/g-C3N4 was also discussed.
