文摘

Novel precursors were used to fabricate iron based catalysts. RRDE current was well correlated with cathode polarization current and power generated. Several Fe-based catalysts outperformed Pt. Fe-Ricobendazole, Fe-Niclosamide and Fe-Pyrazinamide had power density above 200 μWcm−2. Power density is directly related with N coordinated to metal and pyridinic and pyrrolic types.
