Catalytic activity of copper-manganese mixed oxide nanoparticles (Cu/Mn = 1 : 2) prepared by coprecipitation method has been studied for selective oxidation of benzyl alcohol using molecular oxygen as an oxidizing agent. The copper-manganese (CuMn2) oxide catalyst exhibited high specific activity of 15.04 mmolg−1 h−1in oxidation of benzyl alcohol in toluene as solvent. A 100% conversion of the benzyl alcohol was achieved with >99% selectivity to benzaldehyde within a short reaction period at 102°C. It was found that the catalytic performance is dependent on calcination temperature, and best activity was obtained for the catalyst calcined at 300°C. The high catalytic performance of the catalyst can be attributed to the formation of active MnO2phase or absence of less active Mn2O3phase in the mixed CuMn2oxide. The catalyst has been characterized by powder X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer Emmett-Teller (BET) surface area measurement, and Fourier transform infrared (FT-IR) spectroscopies.

Thiol-modified dendritic mesoporous silica nanospheres (DMSNs) supported Au catalyst were facilely prepared and used in gas-phase selective oxidation of benzyl alcohol with O2 as the oxidant. The Au/DMSNs-4.4%SH catalyst with low loading of Au (~2%) and proper amount of thiol ligand (~4.4%) achieved high conversion of benzyl alcohol (Conv. 91%) and selectivity for benzaldehyde (Sel. 98%) and unprecedented lifetime up to 820 h at 250 °C. The dramatically increased lifetime is the consequence of the strong stabilization of active gold nanoparticles by thiol ligand and the effective mass diffusion of DMSNs with opened three-dimensional mesoporous networks.
