摘要
以草酸亚锡和酒石酸锑钾为原料,在260℃用高温水热法一步合成具有纳米结构单分散性的锑掺杂氧化锡纳米导电粉体。用X射线衍射仪、比表面测定仪、透射电子显微镜(transmissionelectronmicroscope,TEM)等表征合成的粉体。结果表明:所合成的粉体均为氧化锡的四方金红石结构,随Sb3+含量的增加,纳米晶粒尺寸减小,结晶性能下降,但粉体的比表面积迅速增加。Sb3+的摩尔分数由1%增加到18%时,粉体的比表面积由70.6m2/g增加到160.7m2/g。TEM显示:粉体的分散性能良好,基本呈单分散状态,随锑掺量的增加晶粒的结晶性能下降。
Monodispersed antimony-doped tin oxide（ATO） conductive nanoparticles were synthesized by directly hydrothermal method at 260 ℃ from the starting materials tin oxalate and tartrated antimony. The obtained nanoparticles were characterized by X-ray diffraction, specific surface area analysis meter and transmission electron microscope（TEM）. The results show that the particles agreed well with the reflections of bulk cassiterite SnO2. The average crystallite size and particle crystallinity decrease with the increase of the antimony doping level. The specific surface area of the particles increase from 70.6 m^2/g of 1% （in mole, the same below） Sb^3＋to 160.7 m^2/g of 18% Sb^3＋. The TEM results show that the nanoparticies are monodispersed and the crystallinity decreases with the increase of Sb ^3＋ dosage.
