Enhancing CO₂ plasma conversion using metal grid catalysts

The synergy between catalysis and plasma chemistry often enhances the yield of chemical reactions in plasma-driven reactors. In case CO2 splitting into CO O2, no positive synergistic effect was observed earlier studies with reactors, except for dielectric barrier discharges, that do not have a high efficiency. Here, we demonstrate introducing metal meshes radio frequency-driven reactors increases relative reaction by 20%–50%, while supported oxide catalysts same setups effect. We attribute this to double role mesh, which acts both as catalyst direct dissociation well oxygen recombination.
