本論文主要是以有機模板合成金屬(Ti、Zr、Sn)矽酸鹽類，藉由有機模版明膠、聚乙二醇(PEG)、脂肪醇聚氧乙烯醚(AEO)當作金屬保護劑，可避免以共沉澱法製備時所造成的金屬聚集，還可以提供高比表面積，其中矽酸鈦材料也應用於催化丙烯環氧化反應，具有很好的轉換率及選擇性。
矽酸錫、矽酸鋯孔洞材料是利用矽酸鈉為氧化矽源並且分別調整到pH5.0與pH4.0後加入有機模板明膠使其水解縮合，再經由100oC水熱12小時分別可得到比表面積約439 m2g-1、613 m2g-1的孔洞材料，且經由DR-UV鑑定後也可確定金屬保有四配位的活性位，接著也利用了PEG以及AEO來取代原來的明膠，在矽酸錫的部分以PEG10000及AEO合成之材料從DR-UV分析會有金屬氧化物聚集的現象，而矽酸鋯以PEG10000、AEO合成之材料皆可獲得高分散度的孔洞材料，比表面積也比明膠合成的還要來的高分別為562 m2g-1、688 m2g-1。
第二部分為矽酸鈦孔洞材料的探討，明膠合成之孔洞材料經由pH值、明膠使用量、水熱時間、水熱溫度、段燒溫度的探討後，選出最佳化的參數，經由表面修飾後發現在pH7.0水熱100oC 16小時並且鍛燒750 oC的矽酸鈦材料應用於催化丙烯環氧化可以得到93.2%的轉換率且95.6%的選擇率，並且將界面活性劑換成PEG4000、AEO後一樣可以得到90.3%、94.8%的高轉換率以及95.2%、95.9%的選擇率。

The traditional methods for the synthesis of mesoporous metal (Ti, Zr, Sn) silicate result in the aggregation of the respective metal dioxide thereby leading to low surface area. To resolve this problem, the present-study uses biodegradable gelatin as an organic template, which disperses the metal species by chelation of the functional group, and the low price sodium silicate was used as silica source. The morphology, surface area, and composition of the prepared metal silicates characterized by IR, SEM and N2 adsorption desorption isothermal. IR spectroscopy reveals a peak at 960~970 cm-1 corresponding to bond of metal-O-Si. The DR-UV-vis spectroscopy provides evidence of well dispersed metal ions in the metal silicate. Moreover, the synthesized mesoporous titanium silicate is used to catalyze the epoxidation of propene with oxidant cumene peroxide. The results show a conversion of 94.5% and a selectivity of 95%. Thus, the present method has significant potential for cost-effective, economical and rapid synthesis of epoxidation compound in commercial factories.
