Title: Tayloring selectivity with different plasma sources                                                                                  


CO2 hydrogenation to methane, Dimethyl Ether or Methanol is nowadays one of the most mature technologies for CO2 catalytic valorisation. However, driven by the thermodynamics at low temperature, the catalytic reaction needs to be assisted in order to take place at low temperature. The use of a DBD plasma has already proved its efficiency in decreasing the reaction temperature by activating the molecules, ions, atoms, presents in the chemical reaction. The optimization of the DBD plasma (pulsed or not) coupled with the optimization and the design of the catalyst is the aim of this PhD research topic. Thus, PhD research activities will focus on the development of a micro-meso-structured optimized catalyst in order to activate CO2 at low temperature (IST CATHPRO) coupled with the optimized dielectric barrier discharge (DBD) plasma assisted CO2 hydrogenation (SU) with a variable geometry (cylindric, parallelepiped, planar etc.). The catalysts will be thoughtfully characterised by state-of-the-art techniques to provide all the needed structural, textural and acid-basic properties for methanol and DME production.
