Pt-less electrocatalysts for the assistance in Oxygen Reduction Reaction, elucidating at the cathode of PEMFC have been widely researched. To be considered as an alternative this research work focuses two different classes of Non-Precious Group Metals (Non-PGM),carbon base supports and Metal Organic Frameworks have been synthesized and tested for ORR characteristics i.e Cobalt doped Graphitic Carbon Nitrides (Co-C3N4) and Zeolitic Imidazole Framework with iron as a dopant i.e Fe+2. Potentiodynamic steady state convectively diffusing the reacting material within the electrolyte is employed at varying rpm to attain Linear Sweep Voltammograms at 20 mV.s-1 in 0.1M KOH and 0.1 HCLO4 electrolytes are obtained at 400, 800,1200 and 1600 rpm. Charge transfer number is obtained, showing the rate determining step of the reaction kinetics of transport of ionic species in the Oxygen reduction.
