Theory of evolution : Potential and solvent effects make the theoretical analysis of electrocatalytic phenomena more difficult than that for gas‐phase catalysis. A simple model based on DFT gives a semiquantitative description of electrocatalytic reaction kinetics for the hydrogen evolution reaction. The figure shows the differential free energy of adsorption of hydrogen on overlayers of Pd on the surfaces of transition metal substrates.
