摘要
通过均匀沉淀法,将NiO复合于玻璃微球表面,制备了纳米NiO/玻璃微球复合粒子。X射线衍射(XRD)、扫描电镜(SEM)结果表明,经过共沉积后,在玻璃微球表面生成一层具有面心结构的NiO层,晶粒尺寸大约为14 nm,这些纳米NiO粒子以丝状胶连的形式附着于玻璃微球表面形成镀层。能谱分析(EDS)结果显示,纳米NiO粒子在玻璃微球表面形成了分布均匀的镀层。傅立叶变换红外光谱仪(FT-IR)表明,所制得的纳米NiO/玻璃微球复合粒子在近红外和远红外波段都表现出良好的红外吸收特性。
The nano-NiO/hollow glass sphere composite particles were successfully prepared by homogeneous precipitation. Scanning electron microscope （SEM）, X-ray diffractometer （XRD） and energy dispersion X-ray （EDS） results indicate that a uniform NiO coating is found on the surface of the hollow glass spheres. The coating is composed of threadlike NiO crystal with face-center-cubic （fcc） crystalline structure. The diameter of NiO crystal in composite particles is about 14 nm. FT-IR results show that the composite particles have better infrared absorption characteristic in both far and near-infrared areas than hollow glass spheres.
