Sumario:Dye wastewater is a serious threat to human health and life. It is an important task for researchers to treat it efficiently. Among many treatment methods, the photo-Fenton method can rapidly degrade organic pollutants. In this study, a ternary photocatalyst, Ag(2)O-NiO/CuFe(2)O(4), was prepared and applied for a photo-Fenton reaction to degrade methylene blue (MB). MB had the best degradation effect when 10 mg of the catalyst were used in an 80 mL reaction system for measurement. The degradation rate of MB was up to 96.67% in 60 min with a high degradation rate constant [Formula: see text]. The total organic carbon (TOC) degradation rate was 78.64% with a TOC degradation rate constant of [Formula: see text]. Therefore, this study fully proves that Ag(2)O-NiO/CuFe(2)O(4) can catalyze the photo-Fenton reaction and effectively degrade MB.
