| Abstract |
Recently, production of hydrogen and oxygen through water splitting has attracted much attention for clean energy source. However, oxygen evolution reaction (OER) is mainly considered as a rate-determining step in water splitting and requires high overpotential to reach a substantial current density in water electrolysis system. Over the past fifty years, considerable effort has been performed to synthesize and develop OER anode materials with efficient reaction rate and lower overpotential. Iridium oxide and ruthenium oxide have been frequently reported showing highly electrocatalytic OER activity. As the use of these noble metals limits their widespread applications, identifying cheap and efficient electrocatalysts for OER is essential. In this study, OER activity of transition metal hydroxides and oxyhydroxides based on relatively earth-abundant elements like nickel and cobalt have been extensively measured. We estimated the reaction efficiency and rate in a view of turnover frequency value and Tafel slope. |
