A synthesis of Cu3(MoO4)2OH2 nanoflowers assembled by nanosheets via chemical precipitation in aqueous solution, understanding their growth mechanism |
| 초록 |
Lindgrenite (Cu3(MoO4)2OH2) nanoflowers were simply fabricated by chemical precipitation technique at room temperature without any surfactant and template. Their morphology, structure, synthesis chemistry, structural and growth mechanism involved in the synthesis process were analyzed. Each Cu3(MoO4)2OH2 showed the formation of pure monoclinic phase and the size of ~10 μm was assembled by thin nanosheets with thickness of ~20 nm using XRD, FE-SEM, HR-TEM. The chemical structure of as-prepared also estimated by FT-IR. A possible growth mechanism for flowers-shaped nanostructures was proposed and discussed. The morphological transformation could be observed during the different reaction time and flower-shaped nanostructures could be maintained at 13, 16 min. Moreover, the effects of pH value and reaction temperature on the morphology of the Cu3(MoO4)2OH2 nanoflowers were studied. The results indicated that the growth condition of the flower-shaped nanostructures was influenced by various factors. Our study demonstrates that these flower-shaped Cu3(MoO4)2OH2 are promising precursor to prepare molybdenum-oxide materials and can be applied in the various fields. |
