Abstract
A problem to be solved by the invention is to provide a production method of a nitrogen-containing carbon alloy that has sufficiently high redox activity or has a large number of reaction electrons of redox reaction. A method for producing a nitrogen-containing carbon alloy comprising baking a precursor containing a nitrogen-containing organic compound and an inorganic metal salt containing one or more kinds of Fe, Co, Ni, Mn and Cr, wherein: the precursor satisfies one of the requirements (a) and (b) below, and, the nitrogen-containing organic compound is one of a compound represented by the formula (1) below, a tautomer of the compound, and a salt and hydrate thereof: (a) the precursor contains the inorganic metal salt in an amount exceeding 45% by mass based on the total amount of the nitrogen-containing organic compound and the inorganic metal salt of the precursor, in which the total amount includes the mass of hydrated water in the nitrogen-containing organic compound and the inorganic metal salt, and the amount of the inorganic metal salt includes the mass of hydrated water in the inorganic metal, (b) the precursor further contains a β-diketone metal complex:
