Abstract: A method for producing a nitrogen-modified mesoporous and dendritic carbon material includes preparing a carbon precursor comprising a metal acetylide. The carbon precursor is mixed with a nitrogen precursor to form a starter mixture. Thereafter, a first heat treatment of the starter mixture is carried out at a temperature in the range of 40 to 80° C. under vacuum to form a metal inclusion compound. In a next step, a second heat treatment is carried out at a temperature in the range of 120 to 220° C. to produce an intermediate by decomposing the metal inclusion compound under a vacuum. The intermediate is treated to remove the metal, and finally consolidation of the treated intermediate is carried out by a third heat treatment at a temperature in the range of 200 to 1000° C. under vacuum or in an inert gas atmosphere to obtain the nitrogen-modified mesoporous and dendritic carbon material.

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.
