Oxygen Reduction Catalytic Activity of Carbon-based Cathode Catalyst Prepared from Polyimide Nano-Particles Containing Fe-Phenanthroline Complex

摘要

Copolymerization of PMDA, TAPB and Fe(amph)3(ClO4)2 has been studied as a synthesis method to prepare Fe containing polyimide nano-particles. The obtained polymer can be converted into a NPM cathode catalyst by carbonization. The resulting carbon-based catalyst exhibits as good ORR performance as a state-of-the-art NPM catalyst. The current method will be suitable for a scaled up process since the incorporation of Fe species into the polymer chains will contribute to uniform dispersion of Fe source.
