摘 要:
According to the environmental problem caused by dye-waste water,methyl orange was photocatalytically degradated by WO3-ZnO composite films.The effects of roasting temperature,roasting time,layers of the composite film,initial concentration of methyl orange,pH and illumination time on the degradation rate were studied.The results indicated that the degradation rate of methyl orange reached to 99.8% when using 3-layers composite film annealed at 300 ℃ for 2 h as catalyst,and the initial concentration of methyl orange was 10 mg / L,pH 11.15,and illumination time was 60 min.
