MoO3 overview: hexagonal plate-like MoO3 nanoparticles prepared by precipitation method

MoO3 nanoparticles are synthesized by precipitation method. The optical, structure and morphology of MoO3 nanoparticles are investigated by UV-Visible spectroscopy (UV-Vis), Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), transmission election microscopy (TEM) and impedance spectroscopy. UV-Vis spectrum confirms the electron transition and the band gap in MoO3 nanoparticles. The presence of functional groups are confirmed by FT-IR spectroscopy. XRD analysis confirms the formation of MoO3 nanoparticles. SEM studies reveal that the MoO3 nanoparticles have hexagonal plate-like structure. EDX spectrum confirms that the obtained product is MoO3. TEM images of the MoO3 nanoparticles show the size and morphology of MoO3 nanoparticles. The electrical and dielectric properties of MoO3 nanoparticles are measured by impedance spectroscopy in the frequency range from 50 Hz to 5 MHz at 303 to 403 K.
