摘要
探讨利用木质素-二氧化硅凝胶制备高比表面稀土催化剂的方法、性能及其在非均相催化体系中稀土催化剂对双氧水的催化行为与效果。结果表明,负载型稀土对双氧水产生羟基自由基氧化染料中间体废水具有明显的增效行为,并对该行为的机理进行了探讨。
The preparation method, capability and catalysis of catalyzer of rare earthes that their carrier is SiO2 are discussed in this paper. Many tests show that this catalyzer plays more actively roles on inducing H2O2 oxidative coupling for treating dye-intermediator wastewater. The mechanism of rare earth-catalyzer is studied too.
