Abstract :
Novel nano-catalysts (Nano ZnO and Fe doped ZnO (Fe(0.1)Zn(0.99)O) were synthesized by co-precipitation method in aqueous solution as new nanocatalysts and characterized by common techniques as FTIR, XRD, SEM and UVD. The size of particles obtained from XRD data is 27 and 16 nanometers for ZnO and Fresno respectively. Influences of doped Fe on ZnO catalytic properties in oxidation of Benzylic alcohols were studied. The oxidation was carried out under mild and green conditions as solvent free, at room temperature and with H2O2. The results show, that FeZnO is better than ZnO as nanocatalyst in oxidation reaction. The rate, of %conversion and %selectivity of reaction is improved in the presence of Fe atoms than ZnO only. The main product of oxidation reactions is Benzaldehyde and/or its derivatives.
