The catalytic effect of the electrode surface is investigated in a dielectric barrier discharge of CO 2 and CH 4 at atmospheric pressure. An increased production of carboxylic acids, especially formic acid, is observed for copper and nickel electrodes. This suggests the occurrence of CO 2 hydrogenation reactions on the metal surface.
