Dissolved Fe species enable a cooperative solid–molecular mechanism for the oxygen evolution reaction on NiFe-based catalysts

The oxygen evolution reaction (OER) on solid catalysts is generally believed to proceed via a four-step process, with each step involving distinct intermediates 1,2,3,4,5,6,7,8,9,10,11,12,13,14. The ...
