Abstract
The present invention discloses a novel process for the fabrication of a class of conductive supported electrocatalysts based on transition metals. The electrocatalysts are formed by pyrolysis of an organometallic polymer complex precursor which is the reaction product of transition metal salts and a templating polymer. The electrocatalysts has enhanced catalytic activity, and are useful in the preparation of supercapacitor and fuel cell electrodes, auto-thermal fuel reformer catalysts, oxygen and hydrogen sensors, zinc-air battery electrode and oxidation catalysts.
