摘要:
制备了钙钛矿型LaCuO3/3DOMCeO2催化剂用于非均相类芬顿反应降解罗丹明B，并通过XRD、SEM和XPS等对该催化剂进行表征。结果表明，LaCuO3/3DOMCeO2呈现三维有序大孔结构。负载3DOMCeO2使LaCuO3的比表面积增大、Cu+含量上升。LaCuO3/3DOMCeO2具有比均相芬顿催化剂更宽的pH适用范围和更高的H2O2利用率。循环使用10 次后，LaCuO3/3DOMCeO2仍具有较高的催化活性。LaCuO3/3DOMCeO2表面存在Cu2+Cu+和Ce4+Ce3+循环，二者协同引发高效类芬顿反应，产生大量·OH和·HO2，实现了对罗丹明B的高效降解。
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.
