摘　　要：本文采用水热法制备了高分散的纳米TiO2粒子,方法新颖、快速、简单。利用XRD对其进行表征。以TiO2作为光催化剂,在紫外光的照射下,系统考察了不同催化剂、催化剂用量、溶液初始pH值等因素对水中水杨酸降解率的影响。In this paper,A novel,simple,fast approach was developed for the synthesis of high-dispersed anatase nano-TiO2 by a hydrothermal synthesis method.The powders are characterized by X-ray diffraction(XRD).The TiO2 photo degradation of salicylic acid in aqueous solutions was investigated by using UV light.The effect of different catalysts,catalysts concentrations,the initial pH value and different inorganic anion were investigated.
