​We are interested in investigating the competitive pathways occurring in the CO2 assisted Ethane Oxidative Dehydrogenation reaction. At the core of our approach is the use of in-situ and operando vibrational spectroscopies to unravel molecular structural changes under real reaction conditions.

Our focus is on the preparation of sulfated mixed metal oxides with controlled surface dispersed active species suitable for alkylation reactions. We aim to investigate the molecular structure as well as the catalytic properties of those materials by means of Operando Raman/FTIR spectroscopies.
