  • Electrode coating with platinum-group metal catalyst and semi-conducting polymer
    Patent number: 4459324
    Abstract: A catalytic electrode has an electrically conductive substrate such as titanium or lead and is provided with a coating comprising a platinum-group metal catalyst finely dispersed in a matrix consisting of a semi-conducting polymer formed in situ on the substrate. The catalyst may be a platinum-group metal oxide such as iridium oxide formed in situ together with the semi-conducting polymer by a controlled heat treatment.The semi-conducting polymer is preferably formed from polyacrylonitrile, polybenzimidazo-pyrrolone or an adamantane based polybenzoxazole.
