Nickel-polymer composite electrode materials have been synthesized using various strategies, all comprising the electrochem. redn. of nickel(II) cations or complexes, incorporated by either ion-exchange or complexation into various poly(pyrrole-carboxylate) thin films coated by oxidative electropolymn. onto carbon electrodes. The electrocatalytic activity and the stability of the different composites have been then evaluated in the course of the electrocatalytic hydrogenation of ketones and enones in aq. electrolytes. The best results were obtained using nickel-polymer composites synthesized by electroredn. of nickel(II) ions complexed into polycarboxylate films, which are characterized by a high catalytic activity and a good operational stability.
