Title (EN) ELECTRODE COATING WITH PLATINUM-GROUP METAL CATALYST AND SEMICONDUCTING POLYMER
(FR) ENROBAGE D'ELECTRODE AVEC CATALYSEUR METALLIQUE DU GROUPE PLATINE ET POLYMERE DE SEMICONDUCTION
Abstract: front page image
(EN)A catalytic electrode has an electrically conductive substrate such as titanium 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 the application of a uniform liquid mixture followed by a controlled heat treatment. The semi-conducting polymer is preferably formed from polyacrylonitrile, polybenzimidazo-pyrrolone or an adamantane based polybenzoxazole.
(FR)Une electrode catalytique possede un substrat electriquement conducteur tel que du titane avec un enrobage comprenant un catalyseur metallique du groupe du platine finement disperse dans une matrice constituee d'un polymere semiconducteur forme in situ sur le substrat. Le catalyseur peut etre un oxyde metallique du groupe platine telle que l'oxyde d'iridium formee in situ avec le polymere de semiconduction par application d'un melange liquide uniforme suivie d'un traitement thermique controle. Le polymere de semiconduction est forme de preference a partir d'un polyacrylonitrile, polybenzimidazopyrrolone ou un polybenzoxazole a base d'adamantane.
