摘要
Abstract
Anatase type nano-TiO2 was prepared by alkali neutralization precipitation using metatitanic acid as materials. And hydroxyapatite (HAP) was synthesized by coprecipitation method with Ca(NO3)2 and (NH4)2HPO4. Then HAP/nano-TiO2 composite material was prepared by impregnation method. The XRD result showed that nano-TiO2 was pure anatase, HAP was pure HAP phase, and the composite material was formed by anatase type nano-TiO2 and HAP with good crystallization. The UV-vis result showed that the photoresponse of HAP/ nano-TiO2 was better than pure TiO2. The photocatalysis degradation experiments results showed that the pho-tocatalytic degradation efficiency was high when the complex mass ratio of HAP and nano TiO2 was 98:2.关键词
