High Performance Cu2 O–CoO/SiC Nanocomposites for Gas-Phase Oxidation of Benzyl Alcohol to Benzaldehyde

High-performance CoO–Cu2 O/SiC is prepared for the gas-phase aerobic oxidation of benzyl alcohol of benzaldehyde, which delivers much higher catalytic performance (92% benzyl alcohol conversion and 99% selectivity at 260 °C) than the solo CoO/SiC and Cu2 O/SiC. TEM image indicates that the small size CoO and Cu2 O nanoparticles are homogeneously distributed on the support. Control experiments indicate that Cu2 O–CoO interfaces are responsible for their better reaction performance.
