Abstract

Neutral HCO3 -/CO2 is a new electrolyte system for in situ generation of robust and efficient Co-derived (Co-Ci) water oxidation electrocatalysts. The Co-Ci/indium tin oxide system shows a remarkable 2.0 mA cm-2 oxygen evolution current density that is sustained for several hours. 7.5 nmol of electroactive species per cm2 generates about 109 μmol of O2 at a rate of 0.51 per mol of catalyst per second.
