Abstract

High surface area carbon-silica xerogels and aerogels were prepared by adding various amounts of activated carbon particles during gelation of tetramethyoxysilane (TMOS). Surface areas and pore structure of the gels were determined by nitrogen and water adsorption and desorption measurements. Carbon increased the surface area of silica gel and the carbon-silica gel composites were found to be hydrophobic. The pore structure of xerogel composites was dominated by carbon whereas that of aerogel composites was apparently controlled by silica component.
