| 摘 要： | 以采用微波辅助法制备的TiO2/Ni光电极为阳极,纤维状石墨毡材料(graphite felt,GF)为阴极,饱和甘汞电极(saturated calomel electrode,SCE)为参比电极建立TiO2/Ni光电催化氧化(PECO)体系.以邻苯二甲酸二甲酯(dimethyphthalate,DMP)为目标物,研究其光电催化降解反应动力学和光电协同作用.结果显示:DMP的降解符合拟一级动力学规律;当DMP初始浓度一定时,影响DMP光电催化降解速率的因素由强到弱依次为:催化剂有效面积,紫外光强度,曝氧速率,外加偏转电压等.实验证明本体系中光电之间具有协同作用.

| Abstract: | A TiO2 /Ni photoelectrocatalytic oxdition(PECO) system was established with TiO2/Ni photoelectrode prepared by microwave-assisted method as anode,graphite felt(GF) as cathode and saturated calomel electrode(SCE)as reference electrode.DMP(dimethy phthalate) was used as target compound to investigate the photoelectrocatalytic degradation kinetics and photo-electro cooperation effect.The result shows that degradation of DMP accords with pseudo first-order kinetics law.When initial concentration of DMP was kept... |
