Restructuring of silver catalysts after oxidation reactions – looking beneath the surface

Year: 2024

Type: conference-paper

Abstract: ConclusionsKinetic data obtained from an annular reactor setup with cylindrical silver catalysts show how the catalyst activity changes with time in various gas mixtures.Microstructural characterisation using primarily FIB-SEM and SPED discloses the silver catalyst restructuring that has occurred after the different oxidation reactions.Distinct changes were documented in terms of grain structure, surface faceting and (sub)-surface pores.By combining the results from the characterisation and the kinetic studies, we explain how the reaction mixture and resulting restructuring affect the catalyst activity.
