Abstract: 用阳极氧化法制备出一种网状Ti/TiO2 电极 ,扫描电镜和拉曼光谱对电极表面TiO2 膜的形貌和晶体结构的检测结果表明 :膜的结构和性能受阳极氧化过程中氧化速率的影响 ,在控制实验条件下 ,锐钛型TiO2 是其主要结晶形态 .若丹明B的光电催化降解和光催化降解的实验结果表明 :外加偏压可以有效地提高有机物的光催化降解效率 .TOC的测定结果显示 ,在光电催化氧化过程中 ,若丹明B几乎完全矿化 .若丹明B在光电催化降解过程中 ,生色基团的破坏与脱乙基作用同时发生
An innovative mesh titanium dioxide (TiO 2) electrode was prepared by anodisation. The morphology and the crystalline texture of the TiO 2 film on electrode were examined by SEM and Raman spectroscopy respectively. The results indicated that the structure and properties of the film depended on anodisation rate, and the anatase was the dominant component under the controlled experimental conditions. Biasing could increase the efficiency of photocatalytic degradation of organic matters. Mineralization Rhodamine B (Rh B) was complete relatively in photoelectro catalytic (PEC) oxidation. Both chromogen destruction of Rh B and de ehtylation in PEC degradation took place simultaneously.
