Abstract

"REVESTIMENTO ELETRO-CATALìTICO COM METAIS DO GRUPO DA PLATINA E ELETRODO FEITO A PARTIR DO MESMO". A presente invenção refere-se a um revestimento eletro-catalítico e a um eletrodo possuindo o revestimento no mesmo, onde o revestimento é um revestimento de óxido de metal misturado, preferívelmente óxidos de metal do grupo da platina, com ou sem níveis baixos de óxidos de metal de válvula. O revestimento eletro-catalítico pode ser utilizado especialmente como um componente de anodo de um célula de eletrólise e em particular uma célula para a eletrólise de soluções aquosas de cloro/álcali.
