摘　　要：采用分步交换法 ,合成了新型的正丙胺、正丁胺柱层状类钙钛矿型钽酸盐C3H7NH3-Sr2Ta3O10 与C4H9NH3-Sr2Ta3O10,采用X射线衍射 (XRD)、扫描电镜 (SEM)、红外光谱 (IR)对该类化合物的结构与形貌进行了表征 ,并测定了其比表面积。Two new amine-pillared treble layered perovskite-like tantalates n-propylNH 3 Sr 2 Ta 3 O 10 and n- butylNH 3 Sr 2 Ta 3 O 10 were successfully prepared using stepwise exchange method.The structure and morphology of resultant pillared complexs were characterized by XRD,TEM and IR,and their specific surface area were also measured.The results showthat amine-pillared treble layered perovsike-like tantalates have been expanded with high specific surface area of about55.5g/cm 3 for n-propylNH 3 Sr 2 Ta 3 O 10 and59.6g/cm 3 n-butylNH 3 Sr 2 Ta 3 O 10 .
