Abstract
A method for producing a catalyst material for an electrode of an electrochemical cell includes doping a carbon material with nitrogen atoms, where the doping includes: bringing a carbon material into contact with urea at a temperature in a temperature range from 750° C. to 850° C.; bringing an oxidized carbon material into contact with cyanamide at a temperature in a temperature range from 550° C. to 650° C.; or bringing an oxidized carbon material into contact with melamine at a temperature in a temperature range from 550° C. to 650° C.
