HAP自组装球的简易合成及其光催化增效作用
Facile Synthesis of Assembly HAP Nanoribbon Spheres and the Synergized Action of Its Photocatalytic Properties
摘要
Abstract
Hydroxyapatite (HAP) nanoribbon spheres with well-defined nanoscale structures and regular morphology were successfully synthesized using a bioactive cooperate template. The spheres are about 5-6 μm in diameter and they form from nanoribbons of 2.5 to 3 |jm in length. The morphologies, structures, and surface areas of the products were studied by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy and Brunauer-Emmett-Teller (BET) analysis. In addition, the products were used as carried materials for the synthesis of the HAP/ZnO composite catalyst. The degradation rate of rhodamine B (RhB) increased by 125% and the recovery increased by 23.1% when using the composite as a catalyst compared with the ZnO nanoparticles. Possible mechanisms for the formation of the HAP assembly microspheres and their synergistic action are also discussed.关键词
