The combination of pulsed corona discharges and catalyst was examined for decomposition of pure carbon dioxide in a corona reactor packed with porous γ-Al2O3 pellets. The decomposition of CO2 was greatly enhanced by packing γ-Al2O3. In the presence of γ-Al2O3, the conversion of CO2, yield of CO reach 23 and 15%, respectively. The CO2 conversion increases with increasing applied voltage and decreasing gas flow rate. The maximum energy efficiency for decomposition of CO2 reaches 318.7 g/kW hr. It was found that high surface area of γ-Al2O3 and strong adsorption capacity of CO2 on γ-Al2O3 play an important role in CO2 decomposition under corona discharges. At the same time, the presence of γ-Al2O3 suppresses the reaction of CO and O.
