‘Operando’ Spectroscopy for Materials and Catalysis – Time and Non-Innocence

This webinar presents the challenges and opportunities of operando Raman spectroscopy to understand chemical reactivity and provide guidance to control and direct reactivity

Operando spectroscopy is a central tool in understanding chemical reactivity and in providing guidance to control and direct reactivity. Spectroscopic characterisation makes use of the full EM spectrum and the choice of technique is largely governed by the characteristics and composition of the material and in particular ‘where’ we look - in bulk or on/at a surface. A furthermore complication is the non-innocence of techniques in such studies especially where changes, either spontaneous or stimulated are followed over time. The challenges and opportunities in the use of operando spectroscopy will be explored in several distinct situations ranging for catalysed reactions, where we look at the role and fate of catalysts as well as the catalysed reaction itself, to catalyst initiated polymerisations. In these examples I will seek to highlight both the challenges and the opportunities that operando spectroscopy, an especially Raman spectroscopy, provides us.
