阶段纯 nanoanatase 被 TiCl4 的大音阶的第五音水解作用在硫酸铵答案准备。为了调查 micros 火车,在 nanoanatase 上完成转变,样品的转变过程被调查由在 situ XRD。基于在里面 situ XRD 数据,直径的一个变化和它的分发,和 nanotitania 粒子的 micros 火车与胜利 XRD 被估计软件。结果证明 nanoanatase 的转变过程能被划分成四步;在从锐钛矿的锐钛矿生长和到金红石的转变之间的一场率比赛决定直径和它锐钛矿 nanoparticles 的尺寸分发;并且在阶段转变期间, micros 火车决定锐钛矿生长和它的转变的率。
Phase pure nanoanatase was prepared by sol-hydrolysis of TiC14 in ammonium sulfate solution. In order to investigate the microstrain effect on nanoanatase transformation, the transformation process of the sample was investigated by in situ XRD. Based on the in situ XRD data, a variation of the diameter and its distribution, and the microstrain of nanotitania particles were estimated with Win XRD software. The results show that the transformation process of nanoanatase can be divided into four steps; a rate competition between the anatase growth and the transformation from anatase to rutile determines the diameter and its size distribution of anatase nanoparticles; and during the phase transformation, the microstrain determines the rates of anatase growth and its transformation.
