CO2 trap, "Tales of MIL-101 Nights"
Nowadays, priority is given to reducing the amount of carbon dioxide in the atmosphere. Chemists have long understood this by designing porous materials capable of trapping this gas. The team of Gérard Férey, CNRS gold medallist in 2010, has shown that MIL-101 powder (Material from the Institut Lavoisier) was an ideal material for storing CO2 at room temperature : a cubic metre is enough to contain around 400 m3 of carbon dioxide at 25°C while the solids already on the market can only capture 200.
In addition to an excellent mastery of the structure of this material, the chemists from the Institut Lavoisier were able to reveal key elements in the experimental and theoretical understanding of the mechanism involved in the fixation of CO2 within the pores (the size of which is about 3.5nm) .
This material shows more than promising performances and should find many industrial applications, particularly in the fight against global warming. But researchers are not intent on stopping at this stage. They are already designing a new generation of materials with even greater storage capabilities.
