Temperature-Dependent Kinetic Parameters for the Alkaline Oxygen Evolution Reaction on NiFeOOH

C) and consists mostly of the free energy of the pre-equilibrium steps. The apparent activation energy at an overpotential of 0.265 V then decreased to ∼13 kJ/mol. Therefore, temperature-dependent studies can provide important mechanistic insights into electrocatalytic reactions, provided care is taken that nonkinetic effects are eliminated.
