Abstract
We 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 h ydroxide films exposed to aqueous LiOH solution. Ion and solvent trans fer rates differ during oxidation and reduction. Even at slow potentia l scan rates, film solvent content is kinetically controlled.
