Fabrication and Photoelectrocatalysis Performance of Expanded Graphite-Supported Anatase Nano Titanium Dioxide
Abstract:
Anatase TiO2 coatings on highly porous expanded graphite(EG) were prepared by equal volume impregnation method. The morphology of EG with and without TiO2 coatings were studied by scanning electron microscope. The XRD pattern of TiO2 power was also studied. The composite material was filled into the novel home-made photoelectric reactor to degrade textile waste water containing reactive blue. The effects of different degradation technologies, such as photocatalysis, electro-oxidation, and photoelectrocatalysis were investigated and compared. The results show that chemical oxygen demand(COD) removal and color removal efficiency of the waste water by photoelectrocatalysis using 0.1 mol/L NaCl as supporting electrolyte is 93.1% and 99.3%, respectively, which are much higher than those obtained by using only photocatalysis or electrocatalysis.
