【Abstract】 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 .更多还原
