Abstract
Un novedoso catalizador mejorado de sulfuro de rodio para la reducción de oxígeno en electrolizadores industriales que es altamente resistente a la corrosión y al envenenamiento por especies orgánicas, quedando así particularmente adecuado para el uso en la electrólisis de ácido clorhídrico acuoso, aún cuando se utilice ácido de grado técnico que contiene contaminantes orgánicos. Modificando el método de preparación, la actividad y la reproducibilidad del catalizador quedan substancialmente mejoradas.
