燃料電池陽極產電，偕同陰極高級氧化程序光電－芬頓系統，可建構具自我操作功能之淨化廢水機能。二氧化鈦（TiO₂）為常用之光催化活性材料，二氧化錫（SnO₂）則可提供金屬良好之抗腐蝕能力。本研究藉由調控相異之電泳沉積時間製備TiO₂/SnO₂複合材料，沉積修飾於SS316L基材表面；研析其對於電化學及抗腐蝕特性之影響，期望能優化光電－芬頓系統之處理效率。實驗包含：（1）線性掃描伏安法（LSV）；（2）循環伏安法（CV）；（3）水接觸角量測；（4）掃描式電子顯微鏡（SEM）；（5）鐵弗曲線腐蝕分析（Tafel）；（6）光電－芬頓系統脫色率量測。結果顯示，沉積時間3分鐘製備之TiO₂/SnO₂/SS316L複合電極獲得最高響應電流為5.16 mA/cm²，及最低腐蝕電流密度48.4 nA/cm²；脫色率相較於SS316L基材提升1.64倍。驗證本製程及參數製備之電極能有效提升系統之處理效能，可進一步深入探討開發與應用。

The fuel cell anode produces electricity, and the cathode combines the photo-electro-Fenton system have a function of self-operated wastewater purification, which construct a self-operated wastewater purification. Titanium dioxide (TiO₂) is a commonly used as photocatalytic material, and tin dioxide (SnO₂) possess the ability to resist corrosion. In this study, TiO₂/SnO₂ composite materials were deposited on the surface of SS316L electrode with different electrophoretic deposition times. The effect on electrochemical and anti-corrosion properties was explored, and it was hoped that the treatment efficiency of the photo-electro-Fenton system could be optimized. The experiment includes: (1) linear scanning voltammetry (LSV); (2) Cyclic voltammetry (CV); (3) Contact angle measurement; (4) Scanning electron microscope (SEM); (5) Tafel curve corrosion analysis; (6) Photo-electro-Fenton system decolorization rate measurement. The results show that the TiO₂/SnO₂/SS316L electrode deposited with 3 minutes obtained the highest response current of 5.16 mA/cm² and the lowest corrosion current density of 48.4 nA/cm² ; the decolorization rate is 1.64 times higher than that of the substrate. It is verified that the electrode prepared by this process and parameters can effectively improve the processing efficiency of the system, and discussion on development and application can be made further.
