Preparation of Composite of CeO2/TiO2 Supported by Expanded Graphite-Activated Carbon and Its Treatment Ability to Phenol

Keywords： expanded graphite based carbon/carbon composite , photo catalysis , TiO2 , phenol

采用沉淀工艺制了CT（CeO2／TiO2）催化剂粉，以膨胀石墨基炭／炭复合材料（EGC）为基体，将CT粉以碳膜包覆的形式引入EGC表面，制得了EGC负载CT催化剂粉的CT／EGC复合材料，研究了其对苯酚的处理性能。结果表明：铈钛物质的量比为0．002的CT催化剂粉处理苯酚的效果最好CT／EGC处理苯酚溶液时，CT粉的光催化能力与EGC的吸附作用存在协同效应，提高了营会材料对蓉酚的灰卜殚静粟．

CT catalyst powders （CeO2/TiO2） had been prepared with precipitation process. Taking expanded graphite based carbon/carbon composite （EGC） as matrix, CT powders were introduced on the EGC surface in the form of carbon-coated, and then CT/EGC composites of CT catalyst powders supported by EGC were obtained, and the property for treating phenol of the composite was studied. The results show that the treatment effect was best when the ratio of amount-of-substrance between Ce and Ti in CT catalyst powders was 0. 002. Synergetic effect between CT photo catalytic performance and EGC adsorption was found when CT/EGC was used to treat the phenol solution, which enhanced the treatment effect of the composite towards phenol.
