钛柱撑粘土的合成

Preparation of titanium-pillared clay

以Ti(OC4H9) 4的水解产物为柱化剂 ,通过离子交换反应制备了最可几孔径为 1.5nm的钛柱撑粘土多孔材料 ,用X射线粉末衍射 (XRD)、差热分析 (DTA)及N2 吸附

Using the hydrolysate of Ti(OC 4H 9) 4 as pillared agent, titanium-pillared clay with mean pore diameter 1.5?nm pore, was prepared by ion-exchange procedure. The mean diameter of pore is 1.5 ?nm for the titanium-pillared clay. The materials were characterized by powder X-ray diffration (XRD), differential thermal analyses(DTA) and N 2 adsorption/desorption analyses.
