| Abstract | |
| A facile hydrothermal synthesis method is developed for the preparation of Cu (II) nanoclusters (with average particle size 6 nm) supported on nanocrystalline tungsten (VI) oxide. Detailed characterization of the material was carried out by XRD, SEM, TEM, ICP-AES and TGA. The catalyst was highly active for selective oxidation of cyclohexane to adipic acid with H2O2. The reusability of the catalyst was tested by conducting same experiments with the spent catalyst and it was found that the catalyst did not show any significant activity loss even after 5 reuses. A cyclohexane conversion of 62.5 % with 27 % adipic acid selectivity was achieved over this catalyst at room temperature. | |
