Abstract

SnO₂ nanoparticles were synthesized by the impregnation method, using SnCl₂Â·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 160Â°C. The novel tin oxide nanoparticles exhibit highly selective response towards ethanol.
