Abstract
- Bi<subscript>2</subscript>WO<subscript>6</subscript> loaded g-C<subscript>3</subscript>N<subscript>4</subscript> 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 Bi<subscript>2</subscript>WO<subscript>6</subscript> particles were loaded on sheet-like g-C<subscript>3</subscript>N<subscript>4</subscript> and formed the heterojunction by chemical change of C, N and O. It was showed that loading g-C<subscript>3</subscript>N<subscript>4</subscript> 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, Bi<subscript>2</subscript>WO<subscript>6</subscript>/g-C<subscript>3</subscript>N<subscript>4</subscript> 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-C<subscript>3</subscript>N<subscript>4</subscript> addition was 0.05 g. This work provided a high-efficiency principle method to synthesize Bi<subscript>2</subscript>WO<subscript>6</subscript> loaded g-C<subscript>3</subscript>N<subscript>4</subscript> composites with the excellent photocatalytic performance for actual produce.
