  Nanocrystalline mixed Magnesium-Zirconyl oxides were prepared by co-precipitation method starting from different organic acid precursors and glycine. The as-prepared nanooxides were characterized by X-Ray Diffraction, TGA-DTA, HR-TEM, electronic absorption spectra and FTIR spectroscopic techniques. The results confirmed the formation of mixed MgO-ZrO2 (cubic, orthorhombic) nanooxides with crystallite size ranging from 10.79-47.55 nm depending on the organic precursors used. The UV-Vis spectroscopy showed the semiconductor nature of the samples with optical energy gap ranging from 2.85-3.00 eV. The morphology and microstructure characteristics were also obtained by High Resolution Transmission Electron Microscopy (HRTEM). The products had been tested as destructive adsorbents for the decontamination of Malathion as VX Chemical Warfare Agent (CWA) stimulant, where it was found that complet.. View More»
