Photocatalytic Oxidation of Methyl Orange Using TiO2/Bamboo Charcoal Doped by Ag
摘要
Abstract
Ag-doped (1 mol％,2mol％,3mol％,4mol％ ) TiO2 loaded on bamboo charcoal (BC) was prepared by impregnation and photocatalytic reduction deposition technique.The as-prepared samples were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM).The results showed Ag doping exist on the surface of TiO2 in the state of silver oxide.When it's used as the catalyst to degrade methyl orange (MO) under visible light,the 2％ Ag-doped sample show the best photocatalytic property.Moreover,the decolorization rate reach 76.8％ in the presence of H2O2.In addition,kinetics parameters of the photocatalytic oxidation of MO were measured and calculated.The result shows photocatalytic oxidation of MO follows first-order kinetics.关键词
