Activation of the Lattice Oxygen Mechanism in NiOOH as an Electrocatalyst for the Oxygen Evolution Reaction: The Role of Anion Intercalation
Source abstract
Abstract
The lattice oxygen mechanism (LOM) of the oxygen evolution reaction (OER) offers significant kinetic advantages over the adsorbed oxygen mechanism. Anion intercalation induces the LOM in NiOOH by enhancing the covalency of lattice oxygen through the modulation of the metal–oxygen electronic state. The relationships between doping mechanisms, such as the size and valence state of anions and the kinetics of the OER, have been clarified. Phosphate-intercalated NiOOH (NiOOH-PO), which benefits from the activated LOM mechanism, has low overpotentials of 195 mV at 10 mA cm –2 and 274 mV at 50 mA cm –2 .
