Provided is a material which can be used in a catalyst layer for a fuel cell and exhibits proton conductive properties. The present invention is directed to a carbon-based solid acid comprising a carbon material having a sulfonic acid group through a linker.

Carbon-based solid acid

Described is a doping technique that forms a stable amorphous silicon film and a stable polycrystalline silicon film at a low temperature and simultaneously that imparts conductivity in an atmospheric pressure environment. A method for producing a compound containing a bond between different elements belonging to Group 4 to Group 15 of the periodic table, the method including: applying, at a low frequency and atmospheric pressure, high voltage to an inside of an electric discharge tube obtained by attaching high-voltage electrodes to a metal tube or an insulator tube or between flat plate electrodes while passing an introduction gas, so as to convert molecules present in the electric discharge tube or between the flat plate electrodes into a plasma; and applying the plasma to substances to be irradiated, the substances to be irradiated being two or more elementary substances or compounds.
