摘要
Abstract
SnCl4·5H2O and SbCl3 were used as the initial materials to prepare antimony-doped tin oxide (ATO) nanoparticles by sol-gel method combined with the supercritical fluid drying technique. The microstructure and doping mechanism of the precursor and the ATO particles were investigated by simultaneous thermogravimetry-differential scanning calorimetry, X-ray diffraction, field emission scanning electron microscopy and transmission electron microscopy. The effect of the drying method and the annealing temperature on the morphology, size, dispersion and crystallinity of particles were also investigated. The mechanism of the super-critical CO2 fluid drying on the precursor alcogels was discussed. The results show that the doped ATO particles with a soft agglomer-ate and a tetragonal phase structure in the size range of 15-30 nm could be obtained.关键词
