Notes:
Spontaneously-deposited Pd-black films were prepared on a Ni mesh. Characterization of the films morphology was performed by Scanning Electron Microscopy. Cyclic voltammetry in 0.1 M NaOH was used to characterize the voltammetric profile in the H-adsorption/absorption region. Contrasting to smooth Pd, the results revealed that the H-adsorption peak can be detected using thiselectrode. It was found that the displacement metal reaction leads to codeposition of Ni during the Pd-black film preparation. The ability of these electrodes to be used on the electrohydrogenation of organic molecules was evaluated using 3-buten-1-ol as a test molecule. It was also analysed the stability of the electrodes upon reusing the same electrode in repetitive electrolysis. It was concluded that the films present avery good catalytic activity to electrohydrogenation but show poor adherence to the substrate when are re-used
