It is well known that zeolite and clays exchanged with several cations are efficient catalysts in Diels-Alder reactions [1]. Moreover, the Ti(IV)/K10-montmorillonite is the most efficient among the clays studied until now [2]. XRD, EXAFS and XANES techniques are used in this work to perform a structural characterization of the catalysts.

Abstract. We present an analysis of the extended X-ray absorption fine structure ( EXAFS) and X-ray absorption near-edge structure (XANES) spectra at the cobalt two of the most important techniques of XAS, which are EXAFS (extended X- ray absorption fine structure) and XANES (X-ray absorption near edge structure).
