ResumoWe report the first dynamic neutron reflectivity measurements on redox switching of a modified electrode. Neutron reflectivity with isotopic substitution of the solvent was used to probe the dynamics of ion and solvent transfer processes in electrochemically precipitated nickel hydroxide films exposed to aqueous LiOH solution. Ion and solvent transfer rates differ during oxidation and reduction. Even at slow potential scan rates, film solvent content is kinetically controlled.
