Abstract
Modification of Pt-black by CeO2 increases its oxidizability in oxygen presence. Adsorption heat of oxygen on modified catalysts is by 15–20 kcal/mol higher than on pure samples.
Abstract
Добавка оксида церия увеличивает склонность платиновой черни к окислению в присутствии кислорода. Теплота адсорбции кислорода на модифицированной черни на 15–20 ккал/моль выше, чем на чистой.
