本研究旨在將光催化氧化分解技術運用在玻璃纖維濾網上，以瞭解其對去除室內VOCs之可行性，進而運用在傳統型電子式濾網之載體上，探討是否可增強其對室內VOCs去除之功效。
本研究利用化學氣相沈積法(chemical vapor deposition, CVD)製備二氧化鈦光觸媒，並披覆於玻璃纖維濾網上，再以120℃烘乾後進行鍛燒(calcination)，最後製成奈米光觸媒玻璃纖維濾網。
本研究首先在某一有價證券印刷廠內實施逸散性揮發性有機物（VOCs）之現場採樣及成份分析；並且針對印刷廠排放之主要VOCs(苯、甲苯、丙酮)以自行設計之批次式光催化反應器進行氧化分解實驗。此外，再針對丙酮分解效率進行操作參數探討，包括VOCs初始濃度、CVD 披覆時間、光觸媒鍛燒溫度，藉以找出光催化分解VOCs的最佳操作條件。
此外，為使本研究方便對載體進行測試，我們特別自行設計了一台具有奈米光觸媒玻璃纖維濾網之空氣清淨機，內載元件包括一組近紫外光燈源、奈米級光觸媒玻璃纖維濾網、不?袗?外殼保護箱及抽氣對流風扇等，並於環境艙室（environmental chamber）中進行功能與效率測試，測試結果顯示塗覆奈米級光觸媒之玻璃纖維濾網確實可有效地去除室內環境中的VOCs。
本研究的最後階段，我們將前述之實驗結果實際運用在一個中度污染的印刷廠作業環境中，並依現場環境現況量身設計一組測試用奈米光觸媒電子式空氣淨化器，設備包括光觸媒反應裝置(含紫外光燈
源、奈米級光觸媒玻璃纖維濾網)、電子濾網、活性碳濾網及鋼板烤漆
外殼之保護箱等，並安裝在現場中央空調系統之回風道內進行功能與效率測試，測試結果顯示披覆奈米級光觸媒之玻璃纖維濾網確實可有效地去除室內環境中的VOCs。

This study investigated the feasibility of glassfiber filter coated with titanium dioxide (TiO2) on removing indoor VOCs using photocatalytic technology, which could further expand the electronic filter’s function .
First of all, we coated the titanium dioxide (TiO2) photocatalysts on the glassfiber filter with chemical vapor desposition (CVD) method, then dried it at 120℃, and calcined it to prepare a nano-sized TiO2 coated filter .
Secondly, we collected VOC samples in a printery and analyzed their chemical components. The main components of VOCs (benzene、toluene and acetone) were then conducted in a self-designed laboratory-scaled batch photocatalytic reactor. The decomposition of acetone for different operating parameters, including initial VOC concentration, CVD coating time, and calcination temperature, was further conducted.
Besides, a nano-sized photocatalyst indoor air purifier was self-designed for this particular study. The air purifier consists of a set of near-UV light source, a nano-sized photocatalyst glassfiber filter, a stainless shelter, and a circulating fan. The air purifier was tested to ascertain its capability on the removal of indoor VOCs in a well-tight environmental chamber. The testing results indicated the nano-sized photocatalyst glassfiber filter can be used to remove indoor VOCs .
In the final stage, a nano-sized TiO2 photocatalyst electronic air cleaner was self-designed for this particular further study in a printery. The air cleaner consists of a set of UV light source, a nano-sized photocatalyst glassfiber filter, a set of electronic filter, carborn filter and a pain coated steel plate shelter. The air cleaner was tested to ascertain its capability on the removal of indoor VOCs in a return air channel of air condition system. The testing results indicated that the nano-sized photocatalyst glassfiber filter can be used to remove indoor VOCs
