Preparation and photocatalytic performances of β2-Siw11Mn/polyaniline/ZnO ternary composites
The ternary composites β2- SiW11Mn/PANI/ZnO were prepared by water bath method, and char?acterized by UV- Vis, TG and SEM. The catalytic activity of the synthesized catalyst for degradation of methyl orange was studied. The effects of catalyst dosage, initial concentration of methyl orange solution and pH on catalytic degradation rate were discussed. The results showed that under the UV lamp of 30 W, the degrada?tion rate could reach 99.63% when pH=8, the optimum amount of catalyst was 25 mg/L, and the concentra?tion of methyl orange solution was 5 mg/L. Compared with the catalysts β2- SiW11Mn and PANI/ZnO, the terna?ry compositesβ2- SiW11Mn/PANI/ZnO exhibited higher photocatalytic degradation property.
