【摘要】 在熔融的LiNO3中,以纳米管钛酸钠为母体进行锂-钠离子交换,制得了具有高表面积的纳米管Li-Ti-O化合物(198.6m·2g-1)。XRD、XPS、TG表征结果表明:此纳米管Li-Ti-O化合物包含两种晶型物质,即立方尖晶石结构的Li2Ti2O4和锐钛矿结构的LixTiO2(x<0.1)],Li+在这两种晶型物质中的结合能不同;在空气中此纳米管Li-Ti-O化合物具有较强的吸水性,化学吸附水在高于400℃时才开始脱附。更多还原

【Abstract】 Nanotube Li-Ti-O compound with high surface(198.6 m2·g-1) was prepared by the method of treating nanotube Na2Ti2O5·H2O in molten LiNO3 and characterized by means of TEM, EDS, XRD XPS and TG. The results show that the nanotube Li-Ti-O compound prepared by this method involves two crystal phases. One is spinel Li2Ti2O4 and another is anatase LixTiO2(x<0.1). Li+ exhibits different Li1s binding energy in the two crystal phases. In ambient air it adsorbs water easily. The chemical adsorped water is difficult to remove below 400 ℃更多还原
