摘要：

SnO2/SiO2 nanocomposite xerogel was synthesized by using the about-to-gel silica sol as "nanoglue". Tin oxide uniformly dispersed within the three-dimension network of the silica in the form of nanoparticles. The SnO2/SiO2 nanocomposite xerogel has a large specific surface area (SSA), which depends on the deposition time of the silica sol. (C) 2002 Elsevier Science B.V. All rights reserved.
