Characterization of metal particle distributions in a supported catalyst

摘要

A catalyst sample may contain both small and large metal particle distributions simultaneously. Characterizing the properties of the metal particles contained in each distribution is important to help describe catalytic performance and optimize catalysts. Monte Carlo simulations and dispersion measurements are employed to determine the relationship between dispersion parameters of each metal particle distribution. Various properties, such as the atom fraction and the surface atom fraction of each distribution can be determined.
