| 摘 要： | 层往化合物因其具有独特的大分子吸附和催化等性能而受到人们的高度重视．至今，人们对层柱粘土和四价金属磷酸盐的制备和表征已作了比较详细和深入的研究k一句，但对一系列以八面体骨架结构为基；出的层状金属氧化物的“插x化学”（intercalationcheAnstry）的研究相对较少，且大部分。作都局限在用有机胺来支撑此类层状金属氧化物［‘－’］由于层间的有机物不耐高温，此类层柱材料在各方面（尤其是催化方面）的应用就受到了很大的限制．合成高热稳定性和大层间距的层柱金属氧化物一直是该领域的研究重。点之一．同层状粘土不同，这类层…

| Abstract: | This note mainly reports a successful preparation of a alumina-pillared layered titanate with a high interlayer spacing through a step-wise exchange process. X-ray diffeaction patterns indicate that the resultant alumina-pillared layered titanate has an interlayer spacing of 1.70 nm, which is 0.17 nm higher than that of previously reported,and has a thermal stability over 500 ℃. The surface area (N2, BET method) of the product is determined to be 72.4 m2·g-1. The N2 adsorption and desorption isotherm of the product demonstrates that the resultant alumina-pillared layered titanate is porous, with both micropores and mesopores. |
