Influence of the alkoxy group on the synthesis of cobaltosic oxide for the reduction of nitrogen oxides

We 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 hydr...

Óxido Cobaltosico Alcoholes Área Superficial Reducción de Óxido Nítrico. We 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). Presentamos una nueva metodología para la síntesis de óxido cobaltosico (Co3O4). Los materiales se prepararon haciendo reaccionar alcoholes de un carbono (C1) a cuatro carbonos (C4) de cadena lateral con sodio metálico y nitrato de cobalto hexahidrato, respectivamente a 600 ºC con flujo de helio. Como efecto de los hidrocarburos de cadena larga, C4 es el mejor precursor de Co3O4, debido a su área superficial más alta que la obtenida por precursores C1, C2, C3. Y todos los catalizadores alcanzaron la conversión de NO a 400 º C en el intervalo de 69.9 % a 97.5 %. Los materiales se caracterizaron por difracción de rayos X (XRD), tamaño promedio de los cristales, área superficial, espectroscopia de dispersión de energía (EDS) y microscopía electrónica de barrido (SEM).
