MoO_3纳米有机溶胶的制备与光致变色性质研究

Study of Preparation and Photochromism of MoO_3 Nanoparticles Organosol

采用表面活性剂CTAB对MoO3水溶胶中的纳米粒子进行表面修饰,通过正戊醇萃取制备了MoO3纳米有机溶胶,对制备有机溶胶的条件进行了系统地研究。TEM分析表明,MoO3纳米粒子呈球形,粒径约为40nm,粒度分布均匀。ED分析表明,MoO3纳米粒子为多晶结构。UV-VIS分析表明,MoO3纳米有机溶胶具有较好的光致变色特性。

MoO3 organosol was obtained by using surface active agent CTAB to modify the nanoparticles in MoO3 hydrosol and n-pentanol to extract MoO3 nanoparticles modified by CTAB. The effect factors on organosol were discussed systematically. TEM photos showed that the MoO3 nanoparticles were spherical in shape, the size was about 40 nm, particle size distribution was in narrow range. ED images indicated that the MoO3 nanoparticles were polycrystalline structure. UV-VIS ana lysis showed that the MoO3 nanoparticles organosol had good photochromic effect.
