| Abstract: | Nano-TiO2 powder was prepared by neutralization hydrolysis and ordinary hydrolysis method.The effects of preparation method on the powder crystal structure,shape,particle size and photocatalytic activity were characterized by X-ray diffractometry(XRD),transmission electron microscopy(TEM) and UV-Vis technologies.Using degradation of methyl orange as models,the photocatalytic property of composite was tested.The results show that for the purpose of industrial production,the TiO2 powder prepared by neutraliza... |
