The electro-reduction of CO2 was investigated on a polypyrrole-coated copper catalyst, for the first time. The experiments were carried out at different pressure conditions (1, 10, 20, 40 and 60 bars), varying film thicknesses (0.5, 0.9, 1.4, 2.1 and 5.4 mu m) and at different potential values (-0.8, -1.0, -1.5, -2.0, -2.5, -3.0 V Pb(Hg)(x)/PbSO4/SO4-2) in CH3OH/0.1 M LiClO4/H+ electrolyte system. At -0.8 V and -1.0 V, it was obtained only HCOOH and CH3COOH. At more negative values, gaseous products such as CH4, C2H4, C2H6 and CO were detected, additionally. The coating of copper electro-catalyst with a conducting polymer causes a shifting of the product distribution to hydrocarbons, especially to methane. (C) 2013 Elsevier B.V. All rights reserved.
