Synthesis of TiO_2 Nanoparticles by Hydrothermal Hydrolysis with Titanium Sulfate and Their Optical Absorption Properties AITranslate
Abstract AITranslate
Anatase TiO2 nanoparticles were synthesized by hydrothermal hydrolysis with Ti（SO4）2 as the titanium source and strong ammonia as the precipitant. The samples were analyzed through XRD, SEM, TEM and spectrophotometer. The results show that without strong ammonia, the increase of the reaction time results in little change of TiO2 particle size. By adding strong ammonia,with the increase of pH Value the particle size of TiO2 significantly decreases,but it doesn＇t change when pH value is more than 7. UVVIS analysis shows that the decrease of TiO2 particle size is beneficial to the blue shift of TiO2 absorption peak. Under the conditions of 240 ℃ ,48 h and pH9, square or elliptical TiO2 nanoparticles,with better dispersity and diameter of 20 nm,are synthesized.
