| 摘 要： | 论文以草甘膦锆(ZrGP)为原料、乙二醇和乙醇混合物为共撑物,介绍了一种新型孔材料的合成方法。利用乙醇将草甘膦锆层板撑开后,乙二醇两端的羟基与草甘膦锆内不同层板上的羧基发生脱水成酯反应,进而生成窗口型孔材料。扫描电镜和XRD分析表明,合成得到的材料内部孔径大约为55 nm左右,是典型的大孔。由于所形成的孔壁由无机骨架和有机链共同组成,该孔材料具有较大的比表面积,达到260 m2.g-1。此外,该孔材料孔内存在大量的可配位基团,因而该材料在吸附、催化等领域会有广阔的应用前景。

| Abstract: | Taking zirconium glyphosate (ZrGP) as raw material and a mixture of glycol and ethanol as support material, this paper described a general process to synthetize a new type of porous material. After pushing open the layers of ZrGP by ethanol, this window-type porous compound was formed by esterification between hydroxyls on both ends of glycol and the carboxyls internal laminated panel of ZrGP accompanying with dehydration. SEM image and XRD patterns proved that the pore size distributions of the modified assembly centered at about 55 nm, which was classified as macroporous. Since the formed pore walls were builted up by inorganic skeleton and organic chain, the specific surface area of the sample was determined to 260 m2·g-1. In addition, the new macroporous material will have a great prospect in adsorption and catalysis due to the existance of coordinative groups in pores. |
