The adsorbed kinetics, proton transportation in electrochemical redox process of 4‐pyridyl hydroquinone (4PHQ) self‐assembled monolayer (SAM) modified Pt electrode were studied by electrochemical quartz crystal microbalance (EQCM) in situ. It proved that the electrode was modified by a monolayer and underwent a rapid electron transfer. It was a slow adsorbed kinetic process. The ion transfer in the electrochemical redox at the SAM‐modified electrode surface mainly involved into the hydrate hydrogen ion.
