本論文之目的在探討利用化學氣相沉積法(CVD)製備含鈦金屬之異相觸媒，及其應用於催化辛烯與有機氫過氧化物(包括TBHP(t-Butyl Hydroperoxide)、CHP(Cumene Hydroperoxide))間之環氧化反應，並探討觸媒製備條件的改變對其催化性能的影響。本研究所使用之載體包括Si-MCM-41及SiO2，我們探討CVD溫度之不同及CVD時間之不同對觸媒催化環氧化反應之影響。實驗結果顯示以SiO2為載體時，觸媒在900℃下CVD 3小時製備，其催化辛烯環氧化反應能得到最佳產率，其選擇率為98.5％、產率有97.8％。Ti- SiO2催化辛烯與CHP之環氧化反應為一級反應，其活化能為44.11kJ/mol。鑑定觸媒的方式包括使用X射線繞射分析儀（XRD）、BET表面積分析儀、感應耦合電漿原子光譜分析（ICP-AES）。結果顯示CVD之溫度越高，則載體之XRD特徵波峰變小，表面積下降，載體中的鈦含量也隨之減少。 AbstractThe purpose of this thesis is to prepare Ti-containing catalysts (including Ti-MCM-41 and Ti/SiO2) by chemical vapor deposition method， and to use the CVD prepared catalyst for catalyzing the reactions between 1-Octene and organic hydroperoxides， including TBHP， CHP.The supports used in this study were Si-MCM-41 and SiO2. The temperature and the time for chemical vapor deposition were varied. When the support was SiO2， the catalysts prepared at the deposition temperature of 900℃ for 3 hr had the best catalytic performances for catalyzing the reaction. 1-Octene epoxidation on Ti- SiO2 was a first order reaction with the activation energies of 44.11kJ/mol for CHP.The catalysts were characterized with XRD， BET， and ICP-AES. The experimental results indicated that the increase of CVD temperature resulted in the decrease of XRD peak， surface areas and titanium contents.
