硅藻土负载纳米Fe2O3复合材料的光催化性能研究

摘要

In the research, the diatomite purified was chosen as a carrier of heterogeneous Fenton catalytic material. The novel heterogeneous Fenton composite materials had been synthesized through Fe2O3 nanoparticles loaded on the diatom shell surface. The catalyst was tested the catalytic properties of the catalyst through discoloring Rhodamine B dye from wastewater. The results showed that the decolorization rate of Rhodamine B had reached 98.33% after the reaction 120 min when diatomite loaded Fe2O3 catalyst and H2O2 were added with the light.%本研究选择提纯后的硅藻土充当Fenton催化剂基础载体,采用水解沉淀法将纳米Fe2O3颗粒负载在硅藻壳体表面制备得到一种新型的非均相Fenton复合材料,以罗丹明B作为染料废水检验催化剂的催化性能,研究结果表明,在光照条件下加入硅藻土负载Fe2O3催化剂和H2O2,反应120 min后,罗丹明B的脱色率可达到98.33%.
