Outline of Final Research Achievements |
In the field of metal-air batteries, a bifunctional electrocatalyst able to efficiently catalyze oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) is highly desired to provide theoretically predicted high energy densities. To address this challenge we prepared copper and nickel coordination polymers (CPs) and investigated their stability and electrocatalytic activity towards OER and ORR in alkaline solutions. It is found that CuCP-derived electrocatalyst is active mainly toward OER, while NiCP-derived electrocatalyst can catalyze both OER and ORR in alkaline solutions.

Academic Significance and Societal Importance of the Research Achievements |
A new method to produce active nanocomposite electrocatalysts for oxygen evolution reaction and oxygen reduction reaction in alkaline media is proposed. The method has a potential to reduce the cost of the catalyst used in metal-air batteries and electrolyzers by replacing usage of noble metals.
