1. A method for producing nanoscale hollow inorganic fibrils or nanotubes, comprising moving a carbon-containing substrate within a reaction chamber either through an electric arc in a gap between two electrodes or adjacent an electrode so that an electric arc exists between the electrode and the substrate, with an arc current sufficiently low to cause the nanotubes to form on the substrate by vaporization of the substrate, but without the arc destroying the substrate, as the substrate moves through the arc completely.
