The LPP in charge of the scientific coordination of the European "PIONEER" project dedicated to CO2 recycling by plasma

Recycling CO2 is one of the greatest challenges of our time and of future generations. The use of plasma/catalysis coupling to achieve this is an innovative and ambitious approach, requiring multidisciplinary expertise, for which there was until now no suitable training. Olivier Guaitella, research engineer at LPP, Maria Elena Galvez, Associate Professor at Sorbonne University and Patrick Da Costa, Professor at Sorbonne University built the PIONEER project to train a new generation of experts in this field. PIONEER has won the ITN-EJD call for projects under the 2018-2020 "Marie Sklodowska-Curie Actions" programme, which supports the creation of innovative training networks. PIONEER stands for “Plasma catalysIs for CO2 recycliNg and grEEn chemistRy”.

PIONEER brings together 15 academic partners and 9 industrial partners in 9 countries by funding 15 bipartite thesis grants which include a joint teaching programme provided by seven of the academic partners. Doctoral students will be recruited between April and September 2019. Ultimately, the challenge is to develop innovative processes for the synthesis of fuels from CO2, or platform molecules for more environmentally friendly organic chemistry processes.

Convert CO2 using cold plasmas

Using CO2 as a raw material for the synthesis of other molecules is an attractive idea, but it runs up against the stability of the CO2 molecule, which is very difficult to make reactive. The idea of using cold plasmas for CO2 conversion is based on using the vibrational excitation of the molecule. Indeed the average electron energy in cold plasmas allows a very efficient energy transfer to excite CO2 which can then be dissociated and/or react with other molecules. However, once CO2 is dissociated into CO and O, it is essential to have a means of controlling both the recombination of oxygen atoms, and the reactivity towards other molecules such as H2, or CH4 for example. For this it is necessary to associate plasma with materials taking into account the specificity of the "plasma" medium, i.e. capable of taking advantage of the excited species generated in the plasma and the strong electric fields induced on the surface of the material.

While the first plasma/catalysis researches have so far used conventional catalysts, an exploratory field remains open as to finding specific catalysts for coupling with plasmas. The intrinsically multidisciplinary nature of this challenge justifies PIONEER’s ambition to train experts mastering plasma physics, catalysis and systems engineering.

The scientific subjects associated with PIONEER are numerous, and are already the subject of pre-projects dedicated in particular to the understanding of the vibrational excitation of CO2. This is the case of the ANR JCJC SYCAMORE project started in 2016 by O. Guaitella, but also of several projects within international collaborations, notably the PREMiERE project which already strengthens the links between the LPP and Professor V. Guerra of the IST Lisbon (Portugal) as well as R. Engeln and A. Sobota of the Technical University of Eindhoven (Netherlands).
