Highly Selective Oxidation of Alcohols Using Nano-Sized NiO/TiO2-ZrO2 as a Novel Heterogeneous Catalyst

Nano-sized NiO/TiO2-ZrO2 which was synthesized by adsorption and "two solvents" methods demonstrated very high catalytic activity in the selective oxidation of benzyl alcohols to benzaldehydes with excellent yields and selectivity in short reaction times. The physical and chemical properties of NiO/TiO2-ZrO2 were investigated by XRD, XRF, BET, FT-IR and SEM techniques. Influence of the catalyst support (SBA-15, ZSM-5, TiO2-ZrO2 and Y), type of metal oxide supported, method of loading and amount of nickel nitrate loading have been thoroughly investigated. Moreover, the catalyst has shown excellent reusability in the process
