Synthesis, characterization and hydrophilic properties of nanocrystalline ZnCo2O4 oxide by combustion route

The aim of said study was to obtain nanostructured ZnCo2O4 through self combustion synthesis using cobalt nitrate, iron nitrate as precursors and glycine as a fuel, without the subsequent heat treatments after synthesis. The temperature variation with respect to a sample with constant molar ratio was investigated. The crystallinity ( phases present and crystallite size: estimated by single-line method) of the product obtained was determined by X-ray diffraction (XRD) measurement, thermogravimetric analysis(TG-DTA),scanning electron microscope(SEM),and high resolution transmission electron microscopy (HRTEM). The synthesis method facilitated the production of spinel ZnCo2O4 with crystallite size between 7-37 nm. The densities of sintered oxides was evaluated by different methods are approximately same. The superhydrophilicity of the sintered oxides was investigated by wetting experiments, by the sessile drop technique were carried out at room temperature in air to determine the surface and interfacial interactions
