摘要

The efficient catalytic system for the oxidation of alcohols using the wetness impregnation and hydrazine reduction method under mild reaction conditions has been investigated in detail. This method resulted in uniform Cu nanoparticle dispersion in the 4–6 nm range. The hydrazine reduction method prepares a catalyst with excellent stability and enhanced low-temperature activity, suitable for gas-phase oxidation of non-activated primary and secondary aliphatic and activated benzyl alcohol. Detailed characterization of the Cu-SBA-15 catalyst was performed using XRD, XPS, TG–DTA, and TPR analytical techniques. These techniques reveal that this method effectively makes Cu particles tiny and highly dispersed into channels of SBA-15 and on the external surface of SBA-15. The results indicated that CuO was the primary active component on the supported catalysts before calcination. The Cu₂O grain has excellent dispersion on the nanoscale. This catalytic system resulted in complete conversion and high selectivity at 220 °C and aerobic oxidizing reaction conditions.
