Abstract:
The perovskite catalyst LaCuO3/3DOMCeO2 was prepared for the heterogeneous Fenton-like degradation of rhodamine B and characterized by techniques such as XRD, SEM and XPS. The prepared LaCuO3/3DOMCeO2 exhibited a three?dimensional ordered macroporous structure. The loading of 3DOMCeO2 increased the specific surface area and Cu+ content of LaCuO3. The prepared LaCuO3/3DOMCeO2 had a wider pH adaptation range and a higher H2O2 utilization rate than those of homogeneous Fenton catalyst. The prepared LaCuO3/3DOMCeO2 still showed high catalytic activity after cyclic use for 10 times. There were Cu2+Cu+ and Ce4+Ce3+ cycles on the surface ofLaCuO3/3DOMCeO2. The synergistic effect of the two reactions induced a highly efficient Fenton-like reaction, which produced a large number of ·OH and ·HO2, and realized the efficient degradation of rhodamine B.
