Abstract
A relationship between dispersion and surface-averaged metal particle size is provided so that either dispersion can be determined from measured surface-averaged metal particle size or surface-averaged metal particle size can be determined from measured dispersion. The method can be applied to catalysts having a single metal species as well as catalysts having multiple metal species. The size of the supported metal particles in the catalyst sample may be determined using transmission electron microscopy images of supported metal particles in the catalyst sample. The dispersion of the supported metal particles in the catalyst sample may be determined using chemisorption tests on the catalyst sample.
