Abstract
Bi2WO6 loaded g-C3N4 composites with excellent photocatalytic activity for degradation rhodamine B (RhB) and tetracycline hydrochloride (TCH) was successfully synthesized via a facile and high-yield solvothermal route. The results showed that well-crystallized Bi2WO6 particles were loaded on sheet-like g-C3N4 and formed the heterojunction by chemical change of C, N and O. It was showed that loading g-C3N4 improved the as-prepared composites to own more effective electrical conductivity and narrower band gap, which can enhance the separation and migration of photogenerated electron-holes as so to enhance the photocatalytic activity. Hence, Bi2WO6/g-C3N4 exhibited great photocatalytic activities for degradation of RhB (99.6%, 75 min) and TCH (73.0%, 105 min). In addition, it was determined that the optimal mass of g-C3N4 addition was 0.05 g. This work provided a high-efficiency principle method to synthesize Bi2WO6 loaded g-C3N4 composites with the excellent photocatalytic performance for actual produce.
