CO2 reduction over GaZrOx oxide: disclosing catalyst structure and VO contribution through MES-PSD operando-XAS/PDF

In a sustainable CO2 recycling economy, we are developing GaZrOx/H-SSZ-13 combined catalyst for CO2 direct conversion to high-value products i.e., propane and propylene. We here propose to combine MES-PSD with operando-XAS/PDF at Ga and Zr K-edges to achieve an exhaustive characterization of the two catalysts and to ultimately extract the signal stemming from reactive species as well as reaction kinetics. Furthermore, this beamtime will make the most out of the recent PDF update on BM31 coupling for the first time ever this technique under high pressure/temperature to MES exploiting PSD.
