采用简单的溶剂热法合成了单分散的Ag/锐钛矿型TiO 2核壳纳米粒子。透射电子显微镜（TEM）和X射线衍射（XRD）测试结果表明，所合成的纳米粒子为核壳结构，TiO 2壳层为锐钛矿相。有趣的是，所合成的纳米粒子的光催化降解茜素红（AR）的能力大大增加相比，Dessuga P25。
Monodisperse Ag/Anatase TiO2core–shell nanoparticles were synthesized by a simple solvothermal method. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) measurements confirm that the as-synthesized nanoparticles have the core–shell structure and TiO2shell is anatase phase. Interestingly, the photocatalytic ability of the as-synthesized nanoparticles for degrading alizarin red (AR) is greatly increased compared with that of Dessuga P25.
