METHOD FOR PRODUCING REDOX CATALYST AND USE OF REDOX CATALYST

Provided is a process for producing an oxygen reducing catalyst comprising a step of heat-treating, in a non-oxidizing atmosphere, a catalyst precursor including a compound (i) supplying a carbon element and a nitrogen element by heating in a non-oxidizing atmosphere, and a compound (ii) comprising at least one element of iron and cobalt. The process for producing an oxygen reducing catalyst can provide an oxygen reducing catalyst including at least one of iron and cobalt as a metal and having catalytic performance sufficient in practical uses.
