采用共振散射光谱和分光光度法研究了钛酸四丁酯和水的用量、微波功率和辐照时间对微波高压液相合成ＴｉＯ2 纳米粒子的影响。透射电镜结果表明 ,ＴｉＯ2 纳米粒子呈球形 ,其粒径约为 1 4ｎｍ。ＴｉＯ2 纳米粒子在 350ｎｍ和70 0ｎｍ处产生二个共振散射峰。本实验表明 ,微波高
The effects of dosage of tetrabutyl titanate and water, microwave power and irradiation time on the synthesis of TiO2 nanoparticles in high pressure liquid phase were studied by resonance scattering spectroscopy and spectrophotometry. Transmission electron microscopy showed that the TiO2 nanoparticles were spherical with a particle size of about 14 nm. TiO2 nanoparticles produce two resonance scattering peaks at 350 nm and 70 0 nm. This experiment shows that the microwave is high
