摘要：

SnO2 nanoparticles have been prepared by the sol-gel method using SnCl4 as a precursor and subsequent heat-treatment at 600 degrees C. The structural and chemical properties were investigated using x-ray diffraction, scanning electron microscopy, and x-ray photoelectron spectroscopy. We find SnO2 nanoparticles of tetragonal structure and sizes varying from 10 to 50 nm. The composition of SnO2 nanoparticles is studied using x-ray photoelectron spectroscopy. We find a significant deviation from the bulk SnO2 composition pointing towards a different surface stoichiometry or termination. (C) 2012 Elsevier B.V. All rights reserved.
