Appearance: In crystallite with white color. 外觀:白色結(jié)晶狀晶粒。

The band gaps of the samples declined from 3.4 to 3.2 eV upon the increasing crystallite sizes. 能隙之大小隨著晶粒大小的變化從3.

The crystallite size and surface structure of nano-CeO2 are examined by XRD and TEM. 利用沉淀法制備了納米氧化鈰,并用X射線衍射儀和透射電子顯微鏡對其結(jié)構(gòu)進行表征。

TiO2 film with anatase crystallite and porous structure was available by controlling the preparation conditions. 通過控制制備條件得到的TiO2薄膜具有銳鈦晶型和多孔性結(jié)構(gòu)。

The mixed crystallite consisting of brookite and anatase has the best photocatalytic activity in the all samples. 光催化活性最好的是由板鈦礦相和銳鈦礦相組成的混晶樣品。
