Beatrice Musig

Hi, I’m Beatrice, Italian by origin. Currently, I am working as a PhD student at Instituto de Carboquimica (ICB-CSIC) in Zaragoza and at Sorbonne Université. I studied Bachelor Physics at Università degli Studi di Parma. To further broaden to multidisciplinary topics, I moved to Belgium and then Germany to complete my Master’s studies, joining the NANO Erasmus Mundus (EMM) programme. I loved and valued the rich international experience of EMM, I hope to continue this cultural and scientific exchange by taking the next step as ESR within the PIONEER consortium. My scientific interests revolve around the applications of Nanotechnologies. During my Master’s thesis at TU Dresden, I had the opportunity to delve into environmental applications, which I found very close to my personal concerns and motivation. The topic that I will be researching combines very well my interests: it deals with nanostructured ceria catalysts for plasma-assisted CO2 methanation for the production of green and recycled fuel. I am looking forward to actively join this large European network.

Objectives

Among the different processes for the catalytic valorization of CO2, methanation stands as a promising applicable technology. The association of a catalyst with non-thermal plasma has been recently considered as a tool for boosting CO/CO2 methanation since it is presumed that reactive species produced by plasma can change the rate-determining-step of the catalytic hydrogenation. For this process, nickel-based catalysts have been proposed as a reliable solution, being both nickel and support properties, key parameters on the performance of these catalysts. CeO2 could be a reliable support due to their remarkable redox properties, leading to an exceptional activity in conventional thermal CO2 methanation. The main objective for the ERS will be to determine the key physicochemical features of the catalytic materials that control their catalytic performance, both activity and stability, on the coupled plasma-catalytic process. Research activities will be focused on the development of Ni-based catalysts supported on nanostructured CeO2 with different morphologies such as polyhedral nanocrystals, nanorods or nanocubes produced by alkaline hydrothermal method and ordered mesoporous CeO2 prepared by nanocasting synthesis. The incorporation of Nickel catalytic phase will be carried out by different preparation methods (impregnation, deposition-precipitation) to tailor active site properties. The materials will be thoughtfully characterized by state-of-the-art techniques to analyze relevant nickel active site and support properties such as Ni dispersion, Ni and CeO2 crystallite size, catalyst surface area, CeO2 oxygen storage capacity, number of CeO2 oxygen defects or catalyst reducibility. Further application of catalysts on dielectric barrier discharge (DBD) plasma assisted methanation will be studied with special attention on the effect of applied voltage, catalyst location and reaction temperature.
