Tracking deactivation of zeolite beta with and without a detailed structure model: XRD analysis and in situ studies

X-ray diffraction is extremely powerful to study the structure of well-ordered, crystalline materials. In this paper, researchers from the Catalysis Section, NAFUMA, the Swiss Norwegian Beamlines, and Haldor Topsoe A/S take it one step further, by developing models for advanced diffraction studies of a disordered material, namely the beta zeolite. Despite the tremendous structural complexity caused by the disorder, these new models make it possible to resolve the degree of deactivation of the zeolite catalyst from a single diffractogram.
