The field of plasma-assisted catalysis is continuously growing in the last few years. However, a large breakthrough is still pending. One problem that has received more attention lately [1] is the huge distance between the plasma and the catalytic material that hiders the plasma activated species to interact with the materials surface. To overcome this challenge, multiscale aeromaterials could be the game changer, which have not been studied in this respect until now. With their high porosity, ultra low density and therefore extremely high surface area (several 100 m2/g), they could enhance the plasma-surface interaction at atmospheric pressure.
Different reactor types has been used to, on the one hand, prove the feasibility of plasma ignition inside aeroglass at atmospheric pressure using high voltages at kHz, and on the other hand, prove the transparency of aeromaterials for ions. The ions transmitting through different thicknesses of aeromaterials of different plasmas at sub-atmospheric pressure (ranging from 20 to 80 mbar) has been detected using an ion mass spectrometer.
