摘要：

Hydrogen evolution reaction (HER) was studied on polyaniline (PAn), polypyrrole (PPy) and on aniline/pyrrole (PAn-PPy) copolymer in acidic solutions. The cathodic Tafel slopes (b(c)) and exchange current densities (j(o)) were calculated from Tafel curves obtained in solutions of XM H2SO4 (X = 0.1, 0.2, 0.3, 0.4 and 0.5 M). Activation energies (E-a) were determined. The E-a-values were found to be ca. 26 for PAn, 36.5 for PPy, 40.6 for PAn-PPy and 20.6 kJ mol(-1) for Pt. (C) 2006 Elsevier B.V. All rights reserved.
