Abstract

The Raman characterization of catalysts (as for any material) is generally a difficult task, since the numerous drawbacks affecting this technique, e.g. overlapping with photoemission phenomena and excitation induced sample damaging. These side effects are detrimental toward advanced applications of Raman spectroscopy, as in situ and/or operando ones. If photoemission can be often avoided by changing the excitation wavelength, the sample damaging requires to take advantage of specific tools, developed ad hoc. The aim of this work is to show the potentialities of a novel Raman setup, specifically designed for the in situ study of catalytic materials, where the sample is moved by means of a magnetic-driven sample-holder, reducing the excitation induced damaging to a negligible extent. Various examples related to catalysis field (involving inorganic, organic and mixed systems) are reported to support this statement.
