計畫中文摘要	全氟與多氟烷基物質（Per- and polyfluoroalkyl substances, PFAS）是一類具有高度環境持久性的新興污染物，因其穩定且難以斷裂的碳–氟鍵結構，使其對傳統物理、化學及生物水 處理技術均具顯著抗性與降解困難。全氟辛酸（Perfluorooctanoic acid, PFOA）作為代表性 PFAS 化合物，已在全球多數地下水體中被檢出，且長期暴露可能對生態系統及人體健康構成潛在 威脅。本研究針對 PFOA 去除開發一種兼具吸附與光催化功能的雙功能光催化膜，該膜由 ZSM-5 沸石與二氧化鈦（TiO₂）組成，並利用多巴 胺（Polydopamine, PDA）作為高效界面黏著層，將催化複合材料均勻且穩固地固定於親水性聚偏二氟乙烯（PVDF）膜基材表面。透過 X 射線繞射（XRD）、掃描式電子顯微鏡（SEM）、比表面積分析（BET）及傅立葉轉換紅外光譜（FTIR）等表徵技術，驗證了材料的晶體結構、比表面積及催化活性，顯示複合膜具備優異的結構穩定性與反應潛力。本研究進一步構建一套太陽能驅動的連續流光催化系統，結合紫外光（UV）照射與過氧化氫（H₂O₂）以產生高氧化性的羥基自由基（•OH），有效促進 PFOA的降解反應。實驗結果顯示，含30 wt% TiO₂的複合材料（A30）在8小時內可穩定實現78.5%的 PFOA 去除率，且整體系統具有低能耗、副產物生成量少及長時間穩定運行的優勢，顯示其在現地地下水整治與永續水質淨化領域的高度應用潛力。本技術不僅具備實際推廣可行性，亦有助於推動臺灣於2050 年達成淨零碳排放目標，符合綠色環境修復與循環經濟的發展方向。
計畫英文摘要	Per- and polyfluoroalkyl substances (PFAS) are a class of emerging contaminants characterized by their high environmental persistence and the strong carbon–fluorine (C–F) bonds that resist degradation. As a representative PFAS compound, perfluorooctanoic acid (PFOA) has been widely detected in groundwater worldwide, and long-term exposure poses potential threats to ecosystems and human health. This study developed a bifunctional photocatalytic membrane possessing both adsorption and photocatalytic capabilities for PFOA removal. The membrane was composed of ZSM-5 zeolite and titanium dioxide (TiO₂), with polydopamine (PDA) serving as an interfacial adhesive layer to uniformly and stably immobilize the photocatalyst onto a hydrophilic polyvinylidene fluoride (PVDF) substrate. Material characterization using X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunauer Emmett–Teller (BET) surface area analysis, and Fourier transform infrared spectroscopy (FTIR) confirmed the crystalline structure, high surface area, and catalytic activity of the composite membrane, indicating excellent structural stability and photocatalytic potential. A solar-powered continuous-flow photocatalytic system was further constructed, integrating ultraviolet (UV) irradiation and hydrogen peroxide (H₂O₂) to generate highly oxidative hydroxyl radicals (•OH) that effectively promote PFOA degradation. Experimental results showed that the composite containing 30 wt% TiO₂ (A30) achieved a stable PFOA removal efficiency of 78.5% within 8 hours. The system demonstrated low energy consumption, minimal by-product formation, and long-term operational stability, revealing strong potential for in-situ groundwater remediation and sustainable water purification. This technology not only shows practical applicability but also contributes to Taiwan’s 2050 net-zero carbon emission goals, aligning with the vision of green environmental restoration and circular economy development.
