In this paper, we discuss the degradation characteristics of methylene blue and methyl orange after being mixed with zinc oxide (ZnO) and magnesium oxide (MgO) powders. Five types of ZnO/MgO mixed powders with different molar ratios (ZnO:MgO molar ratios of 0.95:0.05, 0.9:0.1, 0.85:0.15, 0.8:0.2, and 0.75:0.25) and two different catalyst concentrations were used in the experiment. Catalyst concentrations of 0.5 and 0.15 g/L were used to degrade methylene blue and methyl orange, respectively. The results showed that the powder with a molar ratio of 0.9:0.1 had a high degradation efficiency when the catalyst concentration was 0.15 g/L. The degradation of methyl orange was completed within 6 h, and the degradation of methylene orange reached 80% within 2 h.
