Oxygen Reduction Reaction on Chromium Carbide-Derived Carbons

Chromium carbide-derived carbons were synthesized at various temperatures as possible support materials for polymer electrolyte membrane fuel cell catalyst. The physicochemical characterization data demonstrated that synthesis temperature applied affects significantly the carbon crystallographic structure, including graphitization ratio, and micropore and mesopore volume values. The electrochemical measurements in KOH and HClO4 revealed capacitive behaviour of materials and suitability of studied carbons as catalyst supports.
