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.
