•In this paper, two transition metal oxide nanoparticles are synthesized and characterized by XRD, UVD FT-IR and SEM.•Actually, we were studied influence of Cu metal doped on ZnO catalytic activity.•The catalytic performance of ZnO is significantly enhanced by doped Cu metal on nano ZnO.•Benzylic alcohols converted to corresponding aldehyde or ketone by nano CuZnO with H2O2 under room temperature and solvent free for 3 h.
Nano-mushroom ZnO and Cu-doped ZnO were prepared by co-precipitation method and characterized by general techniques. The particle size of ZnO is 28 nm, while it decreased to 17 nm by doping Cu2+ ion on it.Then, catalytic properties of these nanoparticles were studied in oxidation of benzylic alcohols by 30% H2O2 with nano-catalyst at room temperature. The results showed, a solvent free, green, selective, high yield and effective oxidation. Also, the catalytic performance such as: % conversion, % selectivity and rate of reaction of ZnO are significantly enhanced by doped 1% Cu metal cation on nano ZnO. The ketone and aldehyde are the main product of secondary and primary benzylic alcohols respectively under this condition.
