Abstract:

The α-AgVO3 microrods, β-AgVO3 nanowires, and Ag2V4O11 nanowires were synthesized through a simple and facile low-temperature hydrothermal approach without any template or catalyst. The crystalline structure, morphology and optical properties of the as-prepared products were characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), and ultraviolet-visible diffuse reflectance spectra (UV-vis DRS). The UV-vis DRS showed that the α-AgVO3 microrods, β-AgVO3 nanowires, and Ag2V4O11 nanowires presented strong absorption in a wide wavelength range from UV to visible light and their optical band gaps were measured to be 2.54, 2.21, and 1.77 eV, respectively.
