Understanding the material structure-activity correlation in plasma catalytic CO2 conversion

Project description

A systematic study of plasma catalysis

Plasma catalysis is receiving increasing attention due to its tremendous potential as an alternative technology enabling the transition to a more sustainable chemical production. A key example is the conversion of carbon dioxide into basic chemical building blocks, using (renewable) electrical energy. The process involves highly energetic accelerated electrons that produce a cocktail of activated species. To enhance the energy efficiency and cost effectiveness of the process and achieve greater selectivity, materials of various compositions and catalytic activities are being introduced into the dielectric barrier discharge (DBD) plasma. Funded under the Marie Skłodowska-Curie Actions programme, the PLASMACAT project will conduct a systematic study on how material properties ultimately affect the conversion, selectivity and energy efficiency of plasma catalysis.

Objective

Plasma catalysis is a new emerging field of conversion technology, particularly focused on converting relatively stable gases such as CO2 to basic chemical building blocks by using electrical energy. It consist of highly energetic accelerated electrons producing a cocktail of activated species such as ions, radicals and excited species.
To be able to enhance its energy efficiency and create selective conversions, packing materials and catalysts are being introduced in the plasma. Although it is well accepted that there is a mutual interaction of the materials on the plasma properties and vice versa, the underlying mechanisms and even more the specific material properties influencing plasma conversion, selectivity and energy efficiency are still largely unknown. Therefore, a systematic study applying know-how of the applicant and supervisor in controlled material synthesis will be integrated in plasma catalytic studies, a new field of research for the applicant. This will permit a systematic structure-activity correlation, identifying the impact of yet unrevealed material properties on the plasma characteristics and performance (conversion, selectivity and energy efficiency) determined by the specific plasma environment. Focus will be put on studying the impact of metal dispersion and metal support interactions on the plasma characteristics, plasma catalytic conversion and selectivity as well as its stability. Elucidating the role of packing geometry on plasma catalysis is a particular aspect of this MSCA, which is expected to have unique behavior in plasma discharge and characteristics and hence conversion and selectivity. This is a feature distinctive for plasma and not encountered in classical catalytic processes.
