以癸二胺为模板合成十聚钨酸多孔材料

Si,Ti,Ta,Nb,Zr,V,Pt,W,Mo等元,因在物质分离、催化、导电材料上有着极大的应用前景,而引起了人们的高度重视[1－6].两亲性表面活性剂已被证明由于聚集生成胶束而起模板作用,构筑生成多孔材料[7,8].[9].由于二胺无法聚集生成胶束,因此具有与单胺不同的模板机制.Pinnavaia报导[10].而质子化了的二胺阳离子,其模板作用未见报导.本文报导酸性条件下以质子化了的癸二胺为模板合成十聚钨酸多孔材料的研究,同时对其模板作用进行了探讨.1实验部分(1)样品制备将0.001mol癸150mL去离子水中,用浓盐酸调pH值为1.待二胺完全溶解后,将75mL含有等摩…

Synthesis of Decatungstate Microporous Materials Using 1, 10-diaminodecane as Template

A novel Microporous decatungstate was synthesized by using cationic l,10-diaminode-cane as template under mile chemical donditions,This material was construdted from hoghly ordered hexahonal array of 1,10-diaminodecane and decatungstate polyanions.HR-TEM image ahowded that the decatungstate polyanions"packed"around the l,10-diaminodecane moledules.XRD pattern confirmed its hexagonal array(a=b=1.718nm,cunaknown).Atdlplate mechanosm was pro-posed to explain its formation prodess.It is evidenced that l,10-diaminodecane molecules play a crucial role in templating the inorganic framework.the cationic diaminodecane molecules "bond"decatungstate polyanions on esch end via supermolecular interation and thus form bolarform struc-ture units.These units pack together and ahexagonal phasa is constructed.
