Abstract

A comparison of particle size distributions from electron micrographs and oxygen chemisorption capacities on reduced platinum and palladium faujasite X confirms the existence of monodisperse metal phases of narrow aggregate size distribution and excludes a grape structure for the occluded metal particles. For reduced, monodisperse nickel faujasites a degree of reduction can be obtained by this comparison.

Abstract

Сравнение распределений частиц по размерам, исходя из электронных микрографов и емкости кислородной хемосорбции на восстановленных платиновых и палладиевых фауязитах X, подтверждает существование монодисперсных металлических фаз с узким распределением агрегата по размерам и исключает гроздевую структуру для окклюдированных металлических частиц. Степень восстановления восстановленных монодисперсных никелевых фауязитов может быть получена таким сравнением.
