Routes to increase the conversion and the energy efficiency in the splitting of CO2 by a dielectric barrier discharge

摘要: Here, we present routes to increase CO2 conversion into CO using an atmospheric pressure dielectric-barrier discharge. The change in as a function of simple plasma parameters, such power, flow rate, but also frequency, on-and-off power pulse, thickness and the chemical nature dielectric, wall gas temperature, are described. By means in-depth electrical characterization discharge (effective voltage, dielectric current, number lifetime microdischarges), combined with infrared analysis walls reactor, optical emission spectroscopy for mass spectrometry conversion, propose global interpretation effect all experimental parameters on efficiency reaction.
