MODIFIED MATERIAL, AND NITROGEN-CONTAINING ELECTRICALLY CONDUCTIVE CARBON

摘要

Provided is a modified material which can exhibit an excellent redox activity in a redox reaction accompanied by the transfer of electrons and therefore can be used suitably as a material for forming an electrode catalyst for a fuel cell. The modified material can be produced by subjecting a mixture of a nitrogen-containing electrically conductive carbon and a metal complex to any one modification treatment selected from a heating treatment, a radioactive ray irradiation treatment and a discharging treatment, wherein the nitrogen-containing electrically conductive carbon is formed by reacting a functional group or a multiple bond in an electrically conductive carbon with a nitrogen-containing compound.
