| Abstract: | The structure and electrochemical performance of the self-made catalyst of phosphotungstovanadoheteropolyacid were characterized by FTIR,UV and cyclic voltammetry.The methyl orange solution was used as the simulated dye wastewater and the factors affecting the photocatalytic activity of the catalyst were studied.The experimental results show that:The catalyst has Dawson structure and a good electrochemical performance;Under the conditions of catalyst dosage 1.5 g/L,initial methyl orange mass concentration 10mg/L,UV light power 500 W and UV irradiation time 200 min,the degradation rate of methyl orange can reach 98.3%. |
