A voltammetric and FTIR–ATR study of the electropolymerization of phenol on platinum electrodes in carbonate medium Influence of sulfide
Lapuente Aragó, Rocío - Cases Iborra, Francisco Javier - Garcés Terradillos, Pedro - Morallón Núñez, Emilia - Vázquez Picó, José Luis

Formato:	info:eu-repo/semantics/article
Enlaces:	Voltammetry and FTIR–ATR techniques have been employed to investigate polyphenol films formed on platinum surfaces by electrochemical oxidation of phenol. The media used in the electropolymerization were aqueous carbonate solutions, with and without Na2S. The polymeric films created are not…
