摘要:
以TiCl4为主要原料、油酸(OA)为改性剂,通过水热法原位合成油酸修饰的TiO2纳米粒子。采用傅里叶变换红外光谱仪(FT-IR)、X线光电子能谱仪(XPS)和透射电子显微镜(TEM)对试样进行表征。结果表明:TiO2纳米粒子表面出现了油酸修饰层,且油酸的浓度直接影响到纳米粒子的形貌; 随着油酸浓度的增加,棒状晶体含量逐渐增多。当油酸与Ti4+初始摩尔浓度比为0.8:1时,未发生明显团聚现象,此时,油酸修饰的TiO2粒子的亲油性最好,在有机溶剂中的分散性也达到最佳。
Abstract:
Oleic acid(OA)modified TiO2 nanoparticles were synthesized in-situ by a hydrothermal method, in which TiCl4 was used as the precursor and OA as the modifier. The samples were investigated by Fourier transform-infrared spectroscopy(FT-IR), X-ray photoelectron spectroscopy(XPS)and transmission electron microscopy(TEM). The results showed that the layer of OA was observed on the surface of TiO2 nanoparticles. The concentration of OA directly affected the morphology of nanoparticles. The content of rod-shaped nanoparticles gradually increased with the rising of OA concentration. When the initial molar concentration ratio of OA to Ti4+ reached 0.8:1, obvious agglomeration did not occur. Meanwhile, modified TiO2 nanoparticles possessing the best dispersibility and lipophilicity were obtained in the organic solvent.
