摘要：

Bi2WO6 doped with different amounts of carbon were synthesized using hydrothermal method, and their photocatalytic activities for methylene blue degradation under visible-light irradiation were investigated. The prepared samples were characterized by SEM, EDX, DRS, PL, Raman, and EPR measurements. The results suggest that carbon doping has great influences on the visible-light-driven photocatalytic activity of Bi2WO6 as well as its microstructure. The 1.5C-Bi2WO6 hybrid material shows the highest activity, resulting in a 98 % degradation ratio of MB within 3 h under visible-light irradiation. It is further confirmed by photocurrent generation and electro-chemical impedance spectral measurements. The present research provides a simple and valid method for improving the visible-light-responding photocatalytic activity and fabricating different morphologies of Bi2WO6.
