In this study, 4-thiophenol modified glassy carbon electrode was prepared by the reduction of 4-diazothiophenol tetrafluoroborate salt. Silver nanoparticles were attached to the thiophenol modified surface to prepare a thiophenol-silver nanoparticle composite film. 4-Aminothiopenol molecules were deposited by self-assembling technique to form multi-layered nanofilms of TP/SNP/PhNH2 on glassy carbon substrate. These surfaces were characterized by cyclic voltammetry, electrochemical impedance spectroscopy, X-ray photoelectron spectroscopy, reflectance-absorption infrared spectroscopy, and ellips ...Более
2,4-dinitrophenol (DNP) was covalently bonded to glassy carbon substrate by cyclic voltammetry (CV) technique. 2, 4-diaminophenol film (DAPO) was acquired with electrochemical reduction of 2,4-dinitrophenol film (DNPO). Prepared films were characterized by X-ray photoelectron spectroscopy (XPS) and germanium attenuated total reflection infrared (GATR-FT-IR) spectroscopy. A hemispherical germanium ATR element used with p-polarized light at 65° incidence angle yielded high signal/noise IR spectra for monolayer coverage of molecules on glassy carbon substrate. Layer thickness of films was measure ...Более
