Abstract
Aseries of TiO2 with rod,spherical and flower morphologies weresynthesized successfully.The as-prepared catalysts were characterized by XRD、SEM、UV-VIS.Methylene blue(ME) was used as the aimed degradation material to observe the performance of photocatalysis under ultraviolet and visible light.The mechanism of the effect of morphology and structure of TiO2 on photocatalytic performance was analyzed.The results showed:photocatalytic effect of Flower-like(P25) was the best.The high energy facets and theoretic of morphology have an important influence on the photocatalytic of TiO2.
