In article number 1400252 Khurram Saleem Joya and co‐workers report the development of an efficient water oxidation electrocatalyst from simple and easily accessible cobalt in a near‐neutral HCO 3 − /CO 2 system. With an oxygen onset of 1.29 V (NHE) and 2.0 mA cm −2 oxygen evolution current densities (at modest overpotential), this new material shows remarkable stability and efficiency, and a Faradaic efficiency approaching 98%.
