synthesis and characterization of sno2 nanostructures prepared by a facile precipitation method

in this paper, tin dioxide nanoparticles were synthesized by a fast and simple co-precipitation method. for sno2 preparation, we used ammonia as precipitation agent and bis (acetylacetone) ethylene diamineas as capping agent. by changing in sncl4, acacen mole-ratio different morphologies were obtained. this semiconductor nanostructure has photo-catalyst activities and can degrade organic dyes as water pollution. the synthesized materials were characterized by x-ray diffraction (xrd) pattern, scanning electron microscopy (sem) and fourier transform infrared (ftir) spectroscopy. in situ poly vinyl alcohol-tin dioxide nanocomposite was prepared and results show that the sno2 nanostructure can improve flame retardant property of the pva matrix.
