| 摘 要： | 选择生物协同模板,通过简单的控制组装工艺,制备出结构均一有序的羟基磷灰石(HAP)纳米组装球.该纳米组装球整体尺寸约5-6 μm,球体中心部分尺寸约为2.5-3 μm.通过X射线粉末衍射(XRD)、透射电子显微镜(TEM)、扫描电子显微镜(SEM)、傅里叶变换红外(FT-IR)光谱、比表面积(BET)测试等手段对产物形貌、结构和比表面积进行了表征.产物作为催化剂载体,对氧化锌催化降解罗丹明B (RhB)的催化效率提高了125%,催化剂回收率提高了23.1%,有效降低了催化剂的用量,在有机物降解领域具有潜在的应用价值.同时还对产物的控制生成过程和催化增效机理做了初步探讨.

| 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 μm 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. |
