Heterogeneous fenton-like degradation of methyl orange (MO) in water was investigated over CuAl-Layered Double Hydroxide (CuAl-LDH) with high copper ions content prepared by hydrothermal synthesis in dimethyl sulfoxide-water mixed solvent. CuAl-LDH was proved to have a novel spherical morphology with complex secondary structures and possessed very high crystallinity and purity by XRD, FT-IR, EA, ICP, TEM and SEM characterization. The degradation of MO on this material was evaluated via examining catalyst loading, hydrogen peroxide dosage and temperature when the reaction temperature was 40 degrees C, the dosage of LDH and H2O2 were 20 mg and 0.5 mL, respectively. These results indicated the obtained CuAl-LDH exhibited an excellent performance for oxidation degradation of MO by comparing with MgAl-LDH and CuMgAl-LDH, which will be efficient for the practical application in the abatement of organic pollutants.
