The Preparation and Characterization of Rutile TiO_2 Nanocrystal
摘要/Abstract
摘要：
采用低温陈化法和水热法制备了金红石型纳米TiO2 晶体.利用TEM,XRD及BET等方法对纳米TiO2 进行了表征,结果表明低温合成的纳米晶TiO2 为针形聚集体,水热合成出的TiO2 为纳米针.通过计算,不同条件下得到的产物的晶格参数及比表面有明显变化.
Abstract：
Nanocrystal rutile TiO2 was prepared by low-temperature aging method and hydrothermal method respectively. The prepared powders were studied by X ray diffraction (XRD),TEM and BET method.The results show that the morphologies of precipitated particles were needle-shaped agglomerates (rutile) when the reaction was low in temperature. The needle-shaped single crystals (rutile) by hydrothermal synthesis could find.The crystal lattice parameters and specific surface area of precipitated particles have changed obviously.
