最近在讀一篇paper,是有關於chemisy of silica surface的 這是第一段Introduction的內容: Derivatization and modification of the silica surface are enormously important in both pure and applied chemistry. In addition to the popular silylation reactions that facilitate the formation of useful composites and generate a variety of useful “phases” for chromatography,silica-surface modification is extremely useful for “immobilizing” moieties with catalytic activity. 我有幾個問題: 1)silylation是什麼? 2)silica surface又是如合進行催化反應? ps:我有試者找過reference,但是是1986 or 1988年的書學校找不到 再來裡面有一張很重要的NMR圖譜 是用13-C,29-Si,及27-Al去測它的sample 我有學過1-H的NMR,13-C的只會一點點 而29-Si跟27-Al就完全沒學過了 所以... 3) 可否大概講解一下怎麼看29-Si及27-Al的NMR? 以上.......請各位高手解答 十分感謝您的的回應!! --
