Cobalt-copper oxide catalysts and their performance in total oxidation of ethanol.
Original language description
The Co-Cu oxide catalysts prepared from coprecipitated precursors contained a mixture of Co3O4 and CuO (detected by powder XRD and Raman spectroscopy). The TPR results indicated that CuO present in the samples promoted reduction of Co3O4. The most active CoCu41 catalyst was reduced at the lowest temperature, likely due to the high dispersion of CuO on the surface of Co3O4 particles. In contrast, the surface area of the Co-Cu oxide ncatalysts was not critical for their performance in deep oxidation of ethanol. A synergistic effect of Co and Cu components in the catalysts was observed for CoCu41 and CoCu11 samples. The CoCu41 catalysts showed the highest activity and selectivity, achieving 90% conversion to CO2 at 159 °C (compared to 202 and 259 °C observed for the Co and Cu catalysts, respectively).
