以碳球为模板合成氧化铈纳米空心球
Synthesis of CeO2 Hollow Nanosphere Using Carbon Sphere as Template
摘要
Abstract
Carbon sphere template with a diameter of about 300 nm was uniformly coated with CeO2 nanoparticles by inorganic precursor self-assembly. The CeO2 hollow nanospheres were obtained after the carbon sphere template was removed through calcination at a suitable temperature. Transmission electron microscope, selected area electron diffraction, field emission scanning electron microscope, X-ray diffraction, X-ray photoelectron spectrum, thermogravimetry and differential thermal analysis were employed to characterize the structure of the CeO2 hollow nanospheres. The results reveal that the face-centered cubic-phase CeO2 hollow nanospheres with a diameter of about 250 nm as well as the thin shell thickness about 20 nm is prepared. It indicates that this material has good decolorizing performance for methylene blue simulative dyeing wastewater. The decolorizmg rate can reach 95％ for simulative wastewater after 4 h.关键词
