Abstract
The properties of catalysts based on platinum black modified with copper were studied. The free platinum surface area and the amount of the surface copper were determined by potentiodynamic measurements; the isosteric heats of hydrogen adsorption were also measured. The catalysts were tested in gas phase dehydrogenation of cyclohexanol; after the reaction, and also after mere thermal exposition of the catalyst to hydrogen stream, the surface of the catalysts was re-examined.
