Generally, the XRD diffraction pattern of the Ash-MgO catalyst shows a strong and sharp diffraction peak at 2 angles of 28.3°, 32.8°, and 39.5°, which correspond to the (111), (200), and (220)...

MgO is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Mg2+ is bonded to six equivalent O2- atoms to form a mixture of edge and corner-sharing MgO6 octahedra.

2019年1月1日 · MgO nanoparticles (MgO-NPs) were synthesized using sol-gel method and subsequently annealed at 500°C for two hours. Structural analysis of these synthesized nanoparticles was studied through Rietveld analysis of X-ray diffraction analysis (XRD) pattern.

2020年3月1日 · The as-synthesized MgO nanopowders are analyzed using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Field emission scanning electron microscopy (FESEM), photoluminescence (PL) and photocatalytic studies. The XRD results of MgO nanoparticles indicated the cubic structure with the crystallite size of 27 nm.

Physicochemical characterization of as-formed MgO-NPs confirms the successful fabrication of MgO nano-rods (30 – 85 nm) and nano-rectangular (18.6 – 27.6 nm) by harnessing metabolites secreted...

We have carried out a systematic study optimizing the MgO growth via preparation and sputtering conditions and underlayer structures. It was found that to prevent water vapor which is detrimental to MgO 200 growth, the chamber pressure needs to be reduced below 10−8 Torr.

The XRD pattern showed the characteristic peaks of C-dots and MgO. The FTIR spectrum showed that MgO/C-dots possessed the carboxyl functional groups, allowing DOX to be loaded onto...

2021年8月14日 · Rani et al. revealed the structural properties of MgO nanoparticles by Rietveld analysis of X-ray XRD pattern. They found that the average particle size of MgO nanoparticles calculated from SEM images, Scherer equation and modified W–H analysis was non-conforming.

2016年3月1日 · Magnesium oxide (MgO) nanoparticles have been synthesized by wet chemical reaction method. The structural, optical and morphologies of MgO nanoparticles have been characterized by X-ray diffraction (XRD), UV–vis Spectrophotometry, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM).

2021年9月15日 · The structure, morphology, and optical properties of the MgO crystalline were characterized using XRD, SEM, TEM, UV–visible absorption, and photoluminescence (PL) spectroscopy. The XRD results confirmed the formation of the MgO phase.
