Catalytic hydrogenation of carbon dioxide to C_2+alcohols over copper-cobalt spinels (I)

摘要

Several Ci-Co spinels were prepared for higher alcohol synthesis from CO_2 and H_2. They exhibied a promising potential for the reaction with a high selectivity to C_2+ alcohols, but the selectivity decreased when KOH was introduced. XRD characterization showed that the addition of KOH destroyed the metallic Cu and Co cluster. Some results were discussed.
