| Abstract: | CuO-CoO-MnO/SiO_2 nanocomposite aerogels and xerogels were prepared using tetraethyl orthosilicate(TEOS) as Si source,and aqueous solution of Cu,Co and Mn acetates as the precursor via sol-gel process,CO_2 supercritical drying(SCD) technique or ambient pressure drying technique.The microstructure of the CuO-CoO-MnO/SiO_2 nanocomposite aerogels and xerogels were characterized by field emission scanning electron microscopy(FE-SEM),transmission electron microscopy(TEM) and X-ray diffraction(XRD).The specific s... |
| Keywords: | composite aerogel composite xerogel catalyst carrier preparation microstructure |
