摘 要：
The methylene blue was photocatalytically degraded by WO3-ZnO composite films which were prepared through solgel method.The effects of roasting temperature,pH of methylene blue solution,light source,initial concentration and illuminative time on the degradation rate were studied.The results indicated that the degradation rate of methylene blue reached 98.1% if the WO3-ZnO composite films roasted for 2.0 h was placed in 35 mL 5 mg/L,pH 12.47 methylene blue solution and illuminated for 60 min.
