Abstract: A new method for recovering a catalytic metal and carbon nanotubes from a supported catalyst is provided. The carbon nanotube, including carbon nanotube structures, may serve as the support for the catalytic metal. The valence state of the catalytic metal, if not already in the positive state, is raised to a positive state by contacting the supported catalyst with a mild oxidizing agent under conditions which does not destroy the carbon nanotube. The supported catalyst is simultaneously or subsequently contacted with an acid solution to dissolve the catalytic metal without dissolving the carbon nanotube.

Abstract: An integrated method and apparatus to continuously produce purified Single Wall Carbon Nanotubes (SWNT) from a continuous supply of solid carbon powder fed to an induction plasma torch.

Abstract: Hierarchically porous graphitic carbon particles are prepared by an aerosol process using a aqueous solution of a carbon precursor compound in which different sized particles or clusters of silicon oxide species are dispersed. The aerosol is heated to evaporate the solvent. The solid residue is carbonized and non-carbon species removed to obtain small porous particles of graphitic carbon. The interconnected, different size pores in the small carbon particles make them very useful as electrode materials in electrochemical devices, such as supercapacitors, in which efficient ion transport through the pores or the particles is required.
