Combustion Synthesis of NiO-YSZ Precursor Nanocomposites for SOFC Anode and Its Characterization
Abstract: In the present work, the mixture of Nickel Oxide-Yttria Stabilized Zirconia (NiO-YSZ) composites of composition, mNiO–(1–m) Zr0⋅9Y0⋅1 O1⋅95 (m = 0⋅4), anode materials was synthesized by combustion process using glycine as fuel and nitrate as oxidizer. The study of prepared nanocomposites has been done by Fourier transform infrared spectroscopy (FTIR), differential thermal analysis-thermo gravimetric analysis (DTA-TGA), X-ray diffraction (XRD) and scanning electron microscopy (SEM) to determine the powder properties. The …

Synthesis and Characterization of Mn Doped ZnO Nanoparticles by Chemical Precipitation Method
Abstract: Normal 0 false false false EN-IN X-NONE X-NONE Nanosized Mn doped ZnO semiconductor (where Mn 0.5%–2.5%) has been synthesized via a chemical precipitation method using zinc acetate hydrate, MnCl2 in alcoholic medium and utilizing polyvinyl pyrolidone (PVP) as capping agent. A differential thermal analysis (DTA) and a thermo-gravimetric analysis (TGA) where used determine the thermal properties of ZnO:Mn. The structural characteristics were examined using X-ray diffraction (XRD).scanning electron microscopy (SEM) …
