Abstract
The adsorbed kinetics, proton transportation in electrochemical redox proce ss 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 proces s. The ion transfer in the electrochemical redox at the SAM-modified electr ode surface mainly involved into the hydrate hydrogen ion.
