✦ Synopsis

Abstrad-A sodium form of Wyoming smectite was intercalated with hydroxyaluminum cations and saturated with furfuryl alcohol; polymerization and carbonization were done to obtain carbon-smectite composites. Carbons were obtained from the smectite inorganic matrices by washing them with HCl and HF. The synthesized materials were studied by X-ray diffraction, inverse gas chromatography, DTA, and adsorption of nitrogen and methane. Analyses of data indicate the inorganic matrix acts as a limiting pore size former in the carbons washed from smectite precursors.
