電極材料性質對電-芬頓系統處理效能產生顯著影響。本研究以成本低廉及良好導電性之低碳鋼(SPHC)電極，藉由電泳沉積(Electrophoretic Deposition, EPD)，進行製備SPHC 表面披覆還原氧化石墨烯(rGO/SPHC)電極，冀優化SPHC 電極之電化學特性及耐腐蝕性。過程以田口實驗(Taguchi method)分別針對電泳前驅物濃度、沉積電壓及電泳時間進行性能測試。
結果顯示，電泳參數為濃度0.5 mg/mL、電壓30 V 及時間15分鐘，可獲得緻密表面鍍層，並具最大極化阻抗491.84 Ω。而電泳參數為1.00 mg/L、電壓30 V 及時間15 分鐘下所製得rGO/SPHC 電極，偶氮染料(Rh B)脫色率為48.1 %及脫色反應常數0.0204 min-1，分別為未修飾SPHC 電極之2.15 及2.72倍。綜上， rGO/SPHC 電極可促使電-芬頓反應效率及電極耐腐蝕性能獲得提升。

The properties of the electrode material bring in a significant effect for efficiency of the electro-Fenton system. In this study, the SPHC with low cost
and good conductivity was used as electrode, and made reduced Graphene Oxide (rGO) on the surface of SPHC by electrophoretic deposition (EPD). To optimize the electrochemical performance and corrosion resistance of the SPHC electrode, the Taguchi experiment was used to test the property of the concentration, deposition voltage and deposition time.
That results showed that rGO/SPHC prepared with concentration of 0.5 mg/mL, 30 V and deposition time of 15 minutes possess the compact coating, and got the maximum polarized impedance of the electrode 491.84 Ω. The rGO/SPHC electrode prepared with concentration 1.00 mg/L, 30 V and electrophoresis time for 15 minutes. The decolorization rate of Rh B dye was 48.1% and the reaction coefficient was 0.0204 min-1, which was 2.15 and 2.72 times than SPHC, respectively. In summary, the results show that the rGO/SPHC electrode can improve the efficiency of the electro-Fenton and corrosion resistance for electrode.
