| Popis: | For model calculations it is assumed that metal spheroids are randomly distributed on spherical support particles of nearly closest-packed arrangement. Both the metal and the support can be covered with layers or submonolayers of promoter(s) and carbon. The average diameters as well as n, the average number of metal particles on one support sphere, are estimated from total surface area and selective chemisorption measurements and preferably by electron microscopy too |
