Synthesis and Characterization of Hydrophilic and Semiconductor Cadmium Chromite Nanostructures

چکیده مقاله

Cadmium chromite nanostructures were synthesized in high yield by a simple co-precipitation method. CdCr2O4 nanostructures have been achieved using cadmium nitrate tetrahydrate and CrCl3Æ6H2O as precursors by a co-precipitation method. The effects of various parameters including alkaline agent, pH value, reaction temperature, and surfactant type were investigated to discover the optimum conditions, and it was found that the size and morphology of products can be affected by these parameters. The structure, morphology and surface chemistry of CdCr2O4 powder were investigated by x-ray diffraction, scanning electron microscopy and energy dispersive x-ray spectroscopy. X-ray diffraction patterns indicated the chromite spinel phase with good crystallinity and an average crystallite size of approximately 20 nm. The hydrophilicity of the calcined oxides was investigated by wetting experiments and the sessile drop technique which were carried out at room temperature in air to determine the surface and interfacial interactions.
