英文摘要 | vo2(b) was synthesized via a facile hydrothermal process using v2o5 and oxalic acid. the crystal structure and the phase transition of vo2(b) during elevated temperatures in n-2 were investigated by in situ x-ray diffraction (xrd). meanwhile, the morphologies and the crystal structures of the samples obtained by annealing at different temperatures were characterized by field emission scanning electron microscopy (fe-sem), xrd and raman spectroscopy, respectively. the results show that the as-synthesized nano platelet-like monoclinic vo2(b) irreversibly transforms into submicron and micron subsphaeroidal tetragonal vo2(r) between 430 and 700 degrees c. the as-obtained vo2(r) starts to decompose and form magneli phases vno2n-1 (3 <= n <= 9) series compounds at similar to 1000 degrees c, and totally transfers into a corundum v2o3 sintered block at ca. 1200 degrees c. |
