Therefore a novel dual plasma process is developed constructed and the so produced films are analysed by various electrochemical (CV RDE and RRDE) and structural methods (SEM EDX IR XPS conductivity XRD NEXAFS EXAFS and TEM). It is shown that by doing this non noble metal catalysts could be produced without the need of a high temperature treatment. Furthermore the catalytic activity obtained is superior to that of chemically produced metal polypyrrole films.
