Abstract :
SnO2 nanoparticles were synthesized by the impregnation method, using SnCl2·2H2O as the inorganic precursor and mesoporous silica MCM-41 as the hard template. The products are characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Results showed that prepared SnO2 has rutile structure and are in the MCM-41 ordered channels. These SnO2 nanoparticles were carried out on sensing measurements at operating temperatures of 160°C. The novel tin oxide nanoparticles exhibit highly selective response towards ethanol.
