A novel iron (â ¡) polyphthalocyanine catalyst assembled on graphene with significantly enhanced performance for oxygen reduction reaction in alkaline medium

A novel non-noble-metal catalyst for ORR, denoted FePPc/PSS-Gr, has been fabricated through a solvothermal process, which shows high catalytic activity, an facile four-electron pathway, better stability and tolerance to methanol crossover towards ORR in alkaline medium comparable with the commercial Pt/C catalyst.
