In the search for highly active and inexpensive electrocatalysts, two reactions pose a particular challenge: the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). Both are important for the development of better fuel cells, metal-air batteries, and electrolytic water-splitting. Materials such as platinum, iridium oxide and ruthenium oxide are well suited for these reactions, but they are scarce and expensive.
