Abstract

PROCEDIMIENTO PARA LA PREPARACION DE ELECTRODOS PARA USO COMO CATODO EN CELDAS ELECTROLITICAS. CONSISTE EN OBTENER UN CATODO QUE COMPRENDE UNA MATRIZ ELECTRONICAMENTE CONDUCTIVA, TRANSPORTANDO ENCIMA UN DEPOSITO ELECTROCATALITICO SE COLOCA DENTRITA. A LA SUPERFICIE DEL CATODO SE LE DA UNA RUGOSIDAD EN LA ESCALA DE 100 A 500 CM2 DE LA SUPERFICIE GEOMETRICA DEL AREA. AL METAL NOBLE SE LE DA UNA CARGA EN LA ESCALA DE 0,01 A 10 MG. POR CM2. EL CATODO SE HACE A BASE DE NIQUEL, COBRE O ALEACIONES QUE LOS CONTENGAN. A LAS ALEACIONES SE LES AÑADE TAMBIEN HIERRO, COBALTO Y O CROMO. EL DEPOSITO ELECTROCATALITICO SE HACE A BASE DE UNO O MAS METALES DEL GRUPO DE PLATINO, RODIO Y RUTENIO.
