材料部分由前面文章知道由於 MSN 比起有磁性 MSN 的羥基還要多，所以 我們利用 MSN 當作基材來修飾磺酸做為酸性催化劑，雖然它是固體材料可以回 收，不過無法達到完全回收；可以試著把氧化鐵的粒徑變小，使他可以包覆在 MSN 裡面而不是分布在表面或是裡面，這樣的話可以讓被覆蓋住的羥基顯露出 來，使更多的磺酸根可以接上去，所有的催化劑都可以利用磁力回收。
纖維素轉換的部分，可以使 HMF 繼續轉換成 DMF，DMF 就是真正的生質 燃油可以直接和汽油混合使用，要先找出此步驟所需要的催化劑以及所適合的反 應系統，根據初步的實驗我們得知轉化 HMF 至 DMF 的催化劑需要羧酸根來催 化，所以可以找一個有羧酸根的矽烷類並用架接法接上磁性的 MSN；另外根據 文獻記載此反應所用的溶劑為 THF(tetrahydrofuran)並不是 DMSO，所以必須要 克服不同溶劑的問題，關於此問題的初步解決方法有數種，其一就是嘗試在 DMSO 下可否利用催化劑使 HMF 轉化成 DMF，另外則是嘗試在 THF 為溶劑下 可否在水的存在下使果醣轉換成 HMF，則 HMF 轉換成 DMF 就可以直接加入催 化劑做轉換；最後則可以利用萃取的方法將 HMF 從 DMSO 萃取至 THF，再加 入有羧酸根磁性 MSN 做催化劑轉換成 DMF；如此就可以使序列式反應達到最終 目標，也就是纖維素經過四步驟的序列反應轉換成 DMF，並且四種催化劑都可 以很簡易的利用磁力進行回收並做回收次數的測試。
