Electrocatalysis is an interface-dominated process, in which the activity of the catalyst highly relates to the adsorption/desorption behaviors of the reactants/intermediates/products on the active sites. From the perspective of catalyst design, the chemical functionalization on noble metal surfaces will inevitably affect the reaction process, which is considered to be one of the effective strategies to tune the electrocatalytic performance of noble metal nanocrystals.
