摘要：

Cobalt (Co)-doped V2O5 nanowire arrays are prepared using a simple hydrothermal method by controlling appropriate molar ratios of cobaltous acetate (Co(CH3COO)2·4H2O) and ammonium vanadate (NH4VO3). The products are characterized by scanning electron microscopy, X-ray diffraction, transmission electron microscopy and Fourier-transform infrared spectroscopy. The nanowires are identified as cobalt-doped V2O5 when the molar ratio of cobalt/vanadium precursors is less than 0.064 (calculated from raw materials); while as the molar ratio increases t...
