An electrochemical study of 4-aminothiophenol/Pt nanoparticle multilayers on gold electrodes

Abstract:

Quartz crystal microbalance (QCM) measurements of the formation of a4-aminothiophenol (4-ATP) self-assembled monolayer (SAM) at a gold electrode showed that a surface coverage of 118 ng cn-2 was obtained after a 3 h exposure period, indicating that good surface coverage was achieved. Cyclic voltammetry of the ferricyanide redox couple across this SAM modified surface produced similar results to those of a bare electrode; however, the electroreduction of oxygen was found to be impaired. The 4-...
