Synthesis of Bismuth Molybdate Nanowires via Electrodeposition—Heat-Treatment Method

摘要

Here we have successfully fabricated γ-Bi_2MoO_6 nanowires via an electrodeposition–heat-treatment method. The precursors prepared via electrodeposition possess many spheres which are amorphous, consisting of bismuth oxides and molybdenum oxides. After annealing at 450℃ for 2 h in air atmosphere, bismuth molybdate nanowires were synthesized from the sphere precursors. Scanning electron microscopy, electron-dispersive spectroscopy, X-ray diffraction, and selected area electron diffraction measurements were employed to characterize the bismuth molybdate nanowires. A possible growth mechanism for bismuth molybdate nanowires was proposed in this article.
