Abstract
SnO 2 nanoparticles with rutile structure have been successfully synthesized by using a hydrothermal method at low temperature. By increasing the temperature, SnO 2 nanoparticles change to nanorods. In the hydrothermal method, cetyltrimethyl ammonium bromide (CTAB) surfactant plays an important template-directed role. The nanostructures have been characterized by means of XRD, EDX and BET. XRD results show that the nanostructures are crystalline with rutile structure. The morphology of as-prepared samples was characterized by scanning electron microscopy (SEM). Effects of pH, temperature, and precursor type on morphology and nanoparticles diameter are discussed.
