摘要
The two-component mixed oxides FeVOx 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 H2O2 as oxidant. The mixed oxide FeVOx 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 VOx and FeOx on the surface of the catalyst was discussed. The catalyst was easily recovered and reused.
