Mixed Oxides FeVOx for Selective Oxidation of Octanol to Octanal under Solvent-free Condition

The two-component mixed oxides FeVO x with various molar ratio of Fe to V were prepared and their phase composition, structure and morphology were determined by XRD and SEM. This prepared material was employed for liquid-phase oxidation of octanol using H 2 O 2 as oxidant. The mixed oxide FeVO x with 2.5 : 1 of Fe to V molar ratio was found to be an effective catalyst with high selectivity to octanal under solvent-free condition. The relationship between the catalytic performance and phase compositions of the mixed oxides was investigated by the test of its activity and XRD characterization. The catalytic action of the active sites including redox and acidic sites formed by interaction between VO x and FeO x on the surface of the catalyst was discussed. The catalyst was easily recovered and reused.
