Abstract

MnO2-decorated magnesium wire composite (MnO2-M) was fabricated via a simple hydrothermal reaction and accompanied by the calcination process (MnO2/Mn3O4-M). To clarify the optimized reaction condition of δ-MnO2 in the system, the effect of different pH, temperature and pollutant concentration of methyl orange (MO) for degradation process were investigated. Experimental results showed that MnO2-M achieves a high removal rate of 76% (2h, at 25°C) in the presence of H2O2 at pH 2.5, which is higher than that of MnO2/Mn3O4-M (54%). Moreover, reaction temperature and MO dye concentration have little effect on the degradation performance of MnO2-M. This implies the stability of the as-prepared samples and good potential in the application of wastewater treatment.
