Facile fabrication of porous hollow CeO2 microspheres using polystyrene spheres as templates
Source abstract
Abstract
Porous hollow CeO2 microspheres were fabricated using negative-charged PS microspheres as templates by a facile method. The hollow CeO2 microspheres were characterized by X-ray diffraction (XRD), Fourier-transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and N2 adsorption–desorption. The results showed that the as-synthesized hollow CeO2 microspheres are well monodisperse and uniform in size. The porous shells of hollow microspheres are relatively rough and composed of tiny nanoparticles. The external diameter, internal diameter, and shell thickness of hollow CeO2 microspheres are about 190, 160, and 15 nm, respectively. A possible mechanism for the formation of hollow CeO2 spheres was also discussed.
