Nowadays, transition metal oxide (TMO), the semi-conductor molybdenum trioxide (MoO 3 ) is under investigation. MoO 3 is a good choice because of its many industrial applications and alluring...

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 ...

Porous monoliths of MoO3 nanoplates were synthesized from ammonium molybdate (AHM) by freeze-casting and subsequent thermal treatment from 300 to 600 °C. Pure orthorhombic MoO3 phase was...

1995年7月1日 · The infrared and Raman spectra of powder samples of MoO 3 (orthorhombic and monoclinic) and of MoO 3 · x H 2 O (x = 1 3 1 2, 1 and 2) have been recorded and the most characteristic frequencies are discussed with reference to the available structural data and to previous vibrational assignments.

2003年11月1日 · SEM, XPS, and FTIR were employed to study the dispersing behavior of MoO 3 on the inner surface of mesoporous silicate MCM-41. The results showed that the bulk MoO 3 particles vanished and MoO 3 existed as dispersed state …

2005年10月21日 · We report a spectroscopic characterisation of MoO 3, WO 3 and a MoO 3 –WO 3 mixed oxide thin films deposited on alumina and silicon substrates. Absorbance FT-IR and diffuse reflectance UV-Vis-NIR spectra were recorded after treatments in vacuum and after interaction with O 2, NO 2 /O 2, CO/O 2 or pure CO at increasing temperatures up to 673 K.

2018年1月25日 · The optical, structure and morphology of MoO 3 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.

2015年1月10日 · The films annealed at 600 °C have a different FTIR spectrum and exhibit characteristics peaks at 814.4, 993.6 and 1,108.26 cm −1 that two intense peaks seen at 814.4, 993.6 cm −1 were attributed to the Mo=O stretching vibration, which is an indicator for the layered orthorhombic MoO 3 phase.

2024年7月12日 · The formation of Mo-S bonds in the MoO 3 material with the synergistic effect of sulfur doping and oxygen vacancies (designated as S-MoO 3−x) is confirmed using Fourier-transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), and electron paramagnetic resonance (EPR).

2025年1月28日 · The FTIR study found that Fe 2 O 3 -containing borate glasses exhibit better absorption bands than lead-containing borate glasses containing MoO 3 content. Moreover, the intensity of all three bands of Fe 2 O 3 -doped lead borate glasses is higher than that of the corresponding MoO 3 -doped lead borate glasses.
