A Novel Electrode for Value-Generating Anode Reactions in Water Electrolyzers at Industrial Current Densities.

ABSTRACT: Hydrogen generated in electrolyzers is discussed as a key element in future energy scenarios, but oxygen evolution as the standard anode reaction is a complex multi-step reaction requiring a high overpotential. At the same time,it does not add value-the oxygen is typically released into the atmosphere. Alternative anode reactions which can proceed at similar current densities as the hydrogen evolution are, therefore, of highest interest. We have discovered a high-performance electrode based on earth-abundant elements synthesized in the presence of H₂ O₂ , which is able to sustain current densities of close to 1 A cm^-2 for the oxidation of many organic molecules, which are partly needed at high production volumes. Such anode reactions could generate addition
