工業紡織廢水若未經妥善處理，將造成環境與生物不好的影響。近年的研究指出，高級氧化程序（AOP）中的光催化反應與 Photo Fenton-like 反應被認為可有效降解有機污染物。因為反應過程中，會生成具有高氧化能力的自由基，如氫氧自由基（OH•）。
本研究利用溶膠凝膠法製備 TiO2、0.05 LT、0.05 VT 光觸媒。另外，透過簡單、快速、安全的界面反應製備 CuMnFeO4 和複合金屬觸媒。完成的觸媒利用場發射掃瞄式電子顯微鏡（FE-SEM）、高解析 X 光繞射儀（HR-XRD）、原子力顯微鏡（AFM）、紫外光可見光漫反射分光光譜儀（UV-Vis DRS）進行觸媒特性分析。FE-SEM 掃瞄結果知，自製的觸媒，觸媒粒徑皆小於 100 nm，屬於奈米觸媒。TiO2摻雜微量的鑭與釩，會促使 TiO2 的晶相由銳鈦礦轉變為金紅石。
光觸媒利用紫外光進行光催化反應降解 Y2G 與 MB；CuMnFeO4 和複合金屬觸媒則以光強度為 100 mW/cm2 之模擬太陽光進行 Photo Fenton-like 反應降解 RB 來評估觸媒的活性。0.05 LT 在 pH 3 時，對 Y2G 可吸附 75.2 %，在照紫外光時，光催化降解效率可達 96.5 %。在模擬太陽光下，CuMnFeO4 表現良好的降解效率，且有磁性可回收再利用，故適合應用於實埸污染降解。

The insufficient treatment in industrial textile effluents have negative impacts on the environment and organisms. In the recent studies, both photocatalytic reaction and photo Fenton-like reaction are the advance oxidation processes (AOPs) are recognized to be effective in degradation of organic contaminants. The strong oxidation radicals generating in the AOP was like the hydroxyl radical (OH•).
In this study, photocatalysts – TiO2, 0.05LT and 0.05 VT – were prepared by Sol-Gel method. CuMnFeO4 and muti-metal composite catalysts were produced with a simple, fast, safe carrier solvent assisted interfacial reaction process. The characteristics of the product of catalysts was analyzed by field emission scanning microscope (FE-SEM), high resolution X-ray diffractometer (HR-XRD), atomic force microscopy (AFM), UV/Visible diffuse reflectance spectroscopy spectrophotometer (UV-Vis DRS). The particle size of the whole catalysts was less than 100 nm. The transformation of crystalline in TiO2 from anatase to rutile was promoted by doping lanthanum (La) and vanadium (V).
The activity of photocatalysts was performance with yellow 2G (Y2G) and methylene blue (MB) in a photocatalytic process under illumination of ultraviolet (UV) light, and the activity of CuMnFeO4 and muti-metal composite catalysts were demonstrated with rhodamine B (RB) in a photo Fenton-like process under illumination of simulated sun light at 100 mW/cm2.
The removal rate of Y2G was 75.2 % at pH 3 under dark, the rate of degradation of Y2G was 96.5 % at pH 3 under UV light. The high degradation efficiency of CuMnFeO4 under simulated sun light, and the magnetically recyclable property of CuMnFeO4 raised the practicality in the real field.
