Selective oxidation of benzyl alcohol to benzaldehyde has been investigated using molecular oxygen over copper-manganese mixed oxide prepared by co-precipitation method. The results show high conversion of 99% and selectivity of 95% for the oxidation of benzyl alcohol to benzaldehyde in 60 min. Among the 2 compositions (Cu/Mn=1:1 and 1:4) examined, the composition having Cu/Mn molar ratio of 1:4 is found to give higher catalytic activity for selective oxidation of benzyl alcohol to benzaldehyde. The catalytic performance is highly dependent on calcination temperature and shows best activity for the catalyst calcined at 300 °C. The structure of the catalysts has been characterised by scanning electron microscopy (SEM), transmission electron microscopy (TEM), powder X-ray diffraction (XRD), Brunauer Emmett-Teller (BET) surface area measurement and FT-IR spectrophotometry.
