The present article reports the synthesis of silver nanoparticles in silica aerogel matrix by sub-critical drying technique. The catalytic performance of these nanocomposites was evaluated for the selective oxidation of benzene. Silica aerogel with 1, 5, 10 and 25 wt.% of silver was prepared and characterized for their physico-chemical characteristics. The catalytic performance of these samples was evaluated as a function of silver particle size crystallized within the aerogel matrix. The… 
Clean Synthesis of Silver-Silica Aerogels via Supercritical Drying and Impregnation
A simple and clean route to synthesize nano-scale mesoporous silver-silica composite aerogels was described here. The composite aerogels were obtained by adding a silver colloid to an about-to-gel
Soft-templating synthesis and adsorption properties of mesoporous carbons with embedded silver nanoparticles
Mesoporous carbons containing silver nanoparticles have been successfully synthesized under acidic conditions by employing resorcinol and formaldehyde as carbon precursors and triblock copolymer
Growing CeO2 Nanoparticles Within the Nano-Porous Architecture of the SiO2 Aerogel
Interestingly, the CeO2 nanoparticles undergo a very limited crystal growth, with sizes up to only 7 nm in the case of the sample subjected to a 900°C treatment, and the stability of the nanocomposites under high temperature conditions is demonstrated.
