New frontiers in X-ray spectroscopy in heterogeneous catalysis: Using Fe/ZSM-5 as test-system

et al. 2005

We have applied a number of novel X-ray spectroscopic tools to Fe/ZSM-5 systems. Fe/ZSM-5 can be considered as an ideal test-system for the characterization techniques in heterogeneous catalysis. The existence of a large range of sites and structures creates a good testing ground to determine which experimental tools are able to resolve such complex system. In situ soft X-ray absorption provides important information on the valence and electronic structure of iron during treatments, with a time scale down to 30 s. Kb-detected XANES yields unprecedented resolution for pre-edge structures and using hard X-rays can be used under any condition and treatment, including high-pressures. It can be expected that both in situ soft X-ray absorption and Kb-detected XANES become 'standard' tools for catalysis research, similar to traditional XANES and EXAFS today. The X-MCD is also used in this paper but it will probably remain a rather specialized technique in the field of heterogeneous catalysis. Further new developments for catalysis characterization are for all to be expected from X-ray spectro-microscopy, where one will have the possibility to perform the in situ soft X-ray absorption and Kb-detected XANES experiments with nanometer size spatial resolution. #

“…These include: * high-angle annular dark-field imaging with its ability to highlight (through Rutherford scattering) the precise three-dimensional spatial location of heavier elements dispersed on light supports from STEM tomography; [14] * electron-stimulated X-ray emission with the senstivity to detect clusters of a dozen or so atoms (e.g. 10 À21 g of Ru 10 Pt 2 on silica); * the whole energy range provided in electron-energy-loss spectroscopy (EELS)-from plasmon peaks, through nearedge regions corresponding to core-electron EELS [i.e. electron-loss near-edge structure (ELNES)], which carry information which reveals the coordination finger-printing [24] of certain groups such as BO 3 , AlO 4 , AlO 6 , SiO 4 , and SiO 6 ; * ELNES spectra and white-line intensities in EELS often yield reliable information pertaining to, respectively, bond lengths and oxidation states, particularly of transitionmetal ions.…”

Résumé -SOLEIL, un nouvel outil puissant pour les sciences des matériaux -À l'aube des premiers photons disponibles sur l'anneau synchrotron de troisième génération SOLEIL, un état des possibilités offertes en sciences des matériaux sera présenté. La brillance exceptionnelle de cette machine permettra de réduire de plusieurs ordres de grandeur les temps d'acquisition typiques des différentes techniques synchrotrons (spectroscopie d'absorption-EXAFS, diffusion X aux petits et grands angles-SAXS et WAXS, diffraction des rayons X -XRD, spectroscopies et microscopie de photoélectrons -XPS et PEEM, etc.) les transformant en véritables techniques operando pour la caractérisation des matériaux et plus particulièrement des catalyseurs. La résolution spatiale à l'échelle de quelques microns et même submicronique, accessible par microdiffraction et microspectroscopie dans un domaine s'étendant de l'IR lointain aux X durs, pourra être mise à profit pour réaliser une cartographie atomiquement sélective de matériaux, du catalyseur hétérogène en action aux roches réservoirs. Un ensemble de techniques in situ permettra d'accéder à la réactivité de surfaces et de nanoparticules exposées à des flux gazeux contrôlés. La combinaison des techniques synchrotrons (diffraction, absorption et fluorescence X, etc.) ou l'apport d'informations complémentaires par combinaison simultanée de techniques classiques (Raman, UV-Vis, etc.) avec les techniques du synchrotron seront enfin un atout majeur pour la caractérisation operando des matériaux.Abstract -SOLEIL a New Powerful Tool for Materials Science -The first photons delivered by the third generation synchrotron source SOLEIL will be soon available for the scientific community. In this context, this paper presents an overview of the potentialities offered by this new machine for the study of materials. The outstanding brilliance of the SOLEIL source will enable to reduce by several orders of magnitude the data collection time for most of the synchrotron techniques (X-ray absorption spectroscopy -EXAFS, wide and small angle X-ray scattering -WAXS and SAXS, X-ray diffraction -XRD, photoelectron spectroscopy and microscopy-XPS and PEEM, etc.)
