无机-有机杂化介孔材料组装与性能表征

利用表面活化剂诱导合成法和离子印迹技术，通过TEOS和AAPS酸性催化水解和缩聚反应，将氨基嫁接到介孔材料孔壁上，组装出一种新颖的有序的无机-有机杂化材料；通过IR，xRD，TG，DTA，MIP和粒度分析测定，表征了该杂化材料的组成和孔结构。杂化材料对稀土La^3＋离子吸附量测定结果表明：杂化材料可对稀土离子有效捕集，La^3＋印迹杂化材料对模板镧离子比非印迹杂化材料表现出更好的识别选择性。

Assembly and Characterization of Mesoporous Inorganic-organic Hybrid Materials

Using both surfactant-mediated synthesis method and ionic imprinting technique,the amino group was grafted on pore walls of the mesoporous material,a novel ordered hybrid material was assembled via the acid-catalyzed hydrolysis and condensation of TEOS and AAPS.The composition and pore structures were characterized with IR,XRD,TG,DTA,MIP and particle-size analysis. The adsorbing capacities of the hybrid material were determined for La3 , and the result shows that the mesoporous hybrid material is efficient for the capture of rare earth ions,and La3 imprinted hybrid material has a better selectivity of recognition for the templated lanthanum ion than that of non-imprinted hybrid material.
