| Summary: | Electrocatalytic processes of water oxidation and oxygen reduction reactions are getting highlighted due to its importance in the development of electrochemical systems to convert and store energy. Oxygen reduction reaction (ORR) in acid and alkaline aqueous solutions demonstrate kinetics and thermodynamic complexity. In sight of that, electrocatalytic analysis of the Fe II 3 [Fe III (CN) 6 ] 2 ( PB ) and Co II 3 [Fe III/II (CN) 6 ] 2 ( Co-PBA ) thin films (prepared by electrodeposition) for water oxidation reaction (WOR) and oxygen reduction reaction (ORR) were evaluated in acid aqueous solution and in KCl (0.1M) and KNO 3 (0.5M) electrolytes. The PBAs catalysts thin films are highly stable and capable of keeping its catalytic activities during several cycles. |
