The crystal structure of the NPs was determined by an X-ray diffraction (XRD) measurement that was carried out by a Bruker X-ray diffractometer model PW3710 radiation CuK (alpha 1) (wavelength: 1.54 Å). X-ray photoelectron spectroscopy (XPS) analysis was performed using an instrument (Mono...
The techniques employed were XRD, nitrogen adsorption at 196 °C and catalytic conversion of ethanol and isopropanol at 250–400 °C using micropulse technique. The results showed that the supported solids being calcined at 400 °C consisted of well crystallized CuO, NiO, Fe 2 O 3 and AlOOH...
Characterisation was done by XRD, FTIR and Raman spectroscopy. TEM showed that the average particle size of the two samples were 9 nm and 6 nm with a small particle size distribution. FTIR and TG showed that the -Fe 2 O 3 particles were capped with the diol. Mssbauer spectra of the 6...
gamma-Fe2O3 (maghemite) nanocrystals were synthesized by co-precipitation method at room temperature have been used to remove Pb+2 from aqueous solutions. The prepared of this sample was characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and vibrating ...
nanocrystallinecapped gamma-Fe2O3Nanocrystalline gamma-Fe2O3 was prepared by refluxing ferric nitrate in 1,4-butanediol. Characterisation was done by XRD, FTIR and Raman spectroscopy. TEM showed that the average particle size of the two samples were 9 nm and 6 nm with a small particle size ...
Thiourea dioxide was immobilized on -Fe2O3@Cu3Al-LDH magnetic nanoparticles to prepare the -Fe2O3@Cu3Al-LDH-TUD MNPs. The structure and properties of these magnetic nanoparticles were established by FT-IR, EDX, SEM, XRD, and hystogram of particle size analytical methods. The re...
The products were characterized by FTIR, TGA, XRD, and gas sorption analysis. Nitrogen gas adsorption studies for the pure gamma-Fe(2)O(3) samples revealed mesoporous particles with high surface areas in the range of 70-120 m(2) g(-1) after heat treatment at 300 degrees C. The gamma-...
