In the quest for alternative and green energy sources to tackle energy crisis and environmental pollution challenges, hydrogen fuel cells have been receiving notable attention, owing to their high energy conversion efficiency and negligible to zero emission. However, the high cost and sluggish reaction kinetics of conventional platinum catalysts have hindered large-scale commercialization of fuel cells. Iron phthalocyanine (FePc) has been an auspicious electrocatalyst to replace platinum in hydrogen fuel cells for quite some time due to their superior oxygen reduction reaction (ORR) activity and non-precious nature. Immobilizing FePc over graphene substrate leads to enhanced electron conductivity, prevention of FePc aggregation, greater stability, and increased number of active sites, while B doping of the graphene substrate regulates the electronic structure to yield enhanced ORR activity. Focusing on this synergistic effect due to the π-π stacking interaction between of B doped graphene and FePc, we have undertaken a green synthesis approach for functionalizing FePc on B doped graphene and employed various characterization methods to elucidate the underlying physical and electronic structure leading to the catalytic activity. The composite catalyst exhibits outstanding ORR activity with an onset potential of 1.01VRHE, which is on par with commercial 20wt% Pt/C catalyst. The catalyst also displayed a remarkable half-wave potential of 0.9VRHE and a limiting current density of 4.7 mA/cm2 , both of which were higher than that of Pt/C. Such Pt-free composite catalysts offer a promising solution to sustainable fuel cell applications.
