Novel high-temperature reactors for in situ studies of three-way catalysts using turbo-XAS

Abstract

Two novel high-temperature reactors for in situ X-ray absorption spectroscopy (XAS) measurements in fluorescence are presented, each of them being optimized for a particular purpose. The powerful combination of these reactors with the turbo-XAS technique used in a dispersive-XAS beamline permits the study of commercial three-way catalysts under realistic gas composition and temporal conditions. © 2009 International Union of Crystallography.
