Operando XRD and PDF analysis of novel Co-TiO2 catalysts for direct hydrogenation of CO2

The main goal of the proposed experiments is to determine the structure and evolution of phases in novel Co-TiO2 catalysts prepared by flame-spray pyrolysis. These materials are promising catalysts for direct hydrogenation of CO2. Operando XRD and PDF experiments during H2-TPR and reaction in CO2+H2 mixture will be performed. The investigation of the structural properties of Co-TiO2 formed in the course of reduction will allow establishing the structure-activity relationship for this promising material. This information is crucial to identify the role of active Co-sites, support and metal support interactions. Overall these experiments will be instrumental in designing the next generation of cost-efficient catalysts for CO2 hydrogenation.
