Aggregation Features of Monodisperse Palladium Nanoparticles Supported on gamma-Al2O3
Journal Title: Фізика і хімія твердого тіла - Year 2016, Vol 17, Issue 4
Abstract
The production of supported on γ-A12O3 palladium catalysts by colloidal solution deposition method have been improved. Influence of temperature on the structure and dispersion characteristics of supported nanosized palladium particles during catalyst preparation and activation was investigated. It has been shown that at temperatures below 300oC monodisperse particles palladium catalysts are stable. Further temperature increase leads to aggregation of monodisperse metal nanoparticles by the mechanism of reaction-limited aggregation (RLA) to form polydisperse system.
