Characterizing a supported catalyst : a methodological approach
Résumé
The characterization of supported catalysts requires the combination of several physicochemical and spectroscopic techniques in order to investigate the support and active phase composition, morphology and reactivity. The most common techniques used at the laboratory are detailed in this chapter following four lines: identifying and naming the phases; discriminating and describing the active species; measuring the domains and counting the active sites; watching the catalyst live (in situ and operando experiments). Brief insights into technical aspects, specificities of the techniques and limits of applicability are provided.
