| Abstract: | 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. |
