Influence of the alkoxy group on the synthesis of cobaltosic oxide for the reduction of nitrogen oxides
Keywords:Cobaltosic Oxide, C1-C4 Alcohols, Surface Area, Nitric Oxide Reduction.
AbstractWe present a new methodology for cobaltosic oxide (Co3O4) synthesis. The materials were prepared by reacting alcohols of one-carbon (C1) to four-carbons (C4) of lateral chain with metallic sodium and cobalt nitrate hexahydrate, respectively at 600 ºC under helium stream. As effect of long chain hydrocarbons, C4 is the best precursor of Co3O4, because of its higher surface area than the obtained by C1, C2, C3 precursors. And all the catalysts achieved NO conversion at 400 °C in the range of 69.9 % to 97.5 %. The materials were characterized by X-ray diffraction (XRD), average crystal size, surface area, energy dispersive spectroscopy (EDS), and scanning electron microscopy (SEM).
