以沉积沉淀法制备的复合型氧化物CuO-CeO2为催化剂,与H2O2构成多相类Fenton体系.实验结果表明,CuO-CeO2表面为明显的晶型,比表面积大;在正常光照,反应温度为25℃,溶液初始pH为6,硝基苯初始质量浓度为10 mg/L,H2O2投加量为12.5 mmol/L,催化剂投加量为500mg/L的最佳条件下,反应180 rmin,硝基苯的去除率可达到83.78％;其催化氧化过程遵循羟基自由基反应机理;反应过程中溶铜量很少,且多相类Fenton反应起主导作用;催化剂连续重复回收使用5次仍具有良好的催化性能.“,”A CuO-CeO2 heterogeneous catalyst for the Fenton-like reaction with H2O2 was prepared by a deposition-precipitation method.The experimental results showed that CuO-CeO2 showed clear crystal on the surface with a large specific surface area;under the conditions of normal illumination,reaction temperature being 25 ℃,initial pH of the solution being 6,initial mass concentration ofnitrobenzene being 10 mg/L,H2O2 dosage being 12.5 mmol/L and catalyst dosage being 500 mg/L,reaction time was 180 min and the removal rate ofnitrobenzene was 83.78％;the catalytic process followed hydr9xyl radical reaction mechanism.The concentration ofCu2+ was very small during the whole reaction process,and heterogeneous Fenton-like reaction played a dominant role in this system.The activity of catalyst after 5 times of reuse was still good.
