摘要
CO2 decomposition is a very strongly endothermic reaction where very high temperatures are required to thermally dissociate CO2.Radio frequency inductively-coupled plasma enables to selectively activate and dissociate CO2 at room temperature.Tuning the flow rate and the frequency of the radio frequency inductively-coupled plasma gives high yields of CO under mild conditions.Finally the discovery of a plasma catalytic effect has been demonstrated for CO2 dissociation that shows a significant increase of the CO yield by metallic meshes.The metallic meshes become catalysts under exposure to plasma to activate the recombination reaction of atomic O to yield O2,thereby reducing the reaction to convert CO back to CO2.Inductively-coupled hybrid plasma catalysis allows access to study and to utilize high CO2 conversion in a non-thermal plasma regime.This advance offers opportunities to investigate the possibility to use radio frequency inductively-coupled plasma to store superfluous renewable electricity into high-valuable CO in time where the price of renewable electricity is plunging.
