    The carbonization of nanostructures afforded by conducting polymers represents a new route to the preparation of functional nanostructured carbons. The exposure of colloidal polyaniline particles stabilized with poly(N-vinylpyrrolidone) or silica nanoparticles at 650 °C in inert atmosphere led. The original particulate nanostructure of the samples was preserved after carbonization. Thermogravimetric analysis in air revealed their stability to be up to 500 °C. This is comparable with commercial multi-wall carbon nanotubes, which have similar areas of application. The nitrogen-containing carbons are potentially useful as supports for catalysts and in applications where carbon of higher hydrophilicity would be of benefit.
