Electrochemical and spectroelectrochemical characterization of meso-tetra-alkyl...
Paliteiro, Carlos; Sobral, AbílioA series of three meso-tetra-alkyl porphyrins (H2TAPs) were synthesised and their electrochemical properties were studied in dichloromethane containing either tetra-butyl ammonium perclorate (TBAP) or tetra-butyl ammonium hexafluorophosphate TBA(PF6) as supporting electrolyte (SE) by cyclic voltammetry and in situ UV/vis spectroelectrochemistry. Values of E1/2 for the recorded four redox processes of these porp...
Electroreduction of oxygen on a (100)-like polycrystalline gold surface in an a...
Paliteiro, Carlos; Martins, NatérciaIn a previous work from this laboratory, it was shown that it is possible to electrochemically modify a polycrystalline surface of gold so that it behaves towards O2 reduction like the (100) gold plane. To check whether this similarity in behavior is due to the presence on the (100)-like surface of sufficiently large (100) spots, the process of the upd of Pb(II) was used in this work as a probe of the surface c...
