| 摘 要： | 用阳极氧化法制备出一种新型光电极－网状TiO2/Ti电极，用扫描电镜和拉曼光谱对电极表面TiO2膜的形貌和晶体结构检测。结果表明：膜的结构和性能受阳极氧化过程中氧化速度的影响；在控制实验条件下，锐钛型TiO2是其主要结晶形态。染料若丹明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。

| Abstract: | An innovative mesh titanium dioxide (Ti02) electrode was prepared by anodisation. The morphology and the crystalline texture of the Ti02 film on electrode were examined by SEM and Raman spectroscopy respectively. The results indicated that the structure and properties of the fdm 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. Mineralisation Rhodamine B (Rh B) was complete relatively in photoelectro - catalytic (PEC) oxidation. |
