Synthesis of nanosized SnO/ZnO coupled oxides via co-precipitation method

In this paper, SnO/ZnO nanocomposites have been produced via co-precipitation method for the first time. SnCl2, ZnCl2 and NaOH were used as precursors. The synthesized powders were characterized by X-Ray Diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), Brunauer-Emmett-Teller adsorption isotherm (BET) and X-ray florescence (XRF) analyses. Effect of synthesis temperature on the obtained phases, particle size and morphology, crystallite size and specific surface area of produced nanocomposites have been discussed. It has been shown that at lower synthesis temperature only ZnO nanocrystals could be produced, however at higher temperatures SnO/ZnO nanocomposites could be formed and this co-existence of phases affects the powders crystallite sizes, morphologies, particle sizes and specific surface areas.
