Abstract
Surface morphological and X-ray examinations have been carried out on catalyst gauzes exposed to the conditions encountered during the oxidation of ammonia. A model, based upon observations of platinum and rhodium-platinum single crystals is proposed to explain the structural changes that occur on rhodium-platinum alloys during industrial use.
