characterization of casn(oh)6 and casno3 nanostructures synthesized by a new precursor

in this paper, calcium stannate nanoparticles were synthesized by a fast and simple co-precipitation procedure. for casno3 preparation ammonia was used as precipitation agent. the effect of various surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. by changing in ca(sal)2 as a new precursor different morphologies were obtained. ligand as a capping agent with steric hindrance leads to preparation of product with lower particle size. these semiconductor nanostructures have photo-catalyst activities and can degrade organic dyes as water pollution. the synthesized materials were characterized by x-ray diffraction (xrd) technique, scanning electron microscopy (sem) fourier transform infrared (ft-ir) and uv-visible spectroscopy.
