“…3, CO is a main product. A similar experimental result, which shows that CO may be directly produced by plasma decomposition of CO 2 , has been reported by Matsumaru et al 9 As apparent, hydrocarbons could be effectively formed when the flow ratio of H 2 to CO 2 exceeds three.…”

“…The present result is consistent with the experimental observation that CO formation increases with increasing discharge currents. 9,17,18 While the plasma differed at most by 20%, the CEs for hydrocarbons differed by more than 100% ͑Fig. 5, see below͒, enabling us to assume that the catalytic properties can be different between Cu and Fe.…”

“…Gaseous products detected in the present study in the mixture of CO 2 and H 2 were CO, CH 4 , C 2 H 4 , and C 2 H 6 , in accordance with recent research. 8,9,19 In plasma physics, however, the role of electrodes has not been taken into consideration, probably because reactions would proceed under extremely excited conditions where the electrode can play only a limited role. In the present study, a significant difference could be observed between Cu and Fe electrodes, implying that the electrode may play a certain role even in the plasma reactions.…”

“…Mach et al 8 proposed the mechanism for hydrocarbon formation from CO/H 2 to CH 4 . Matsumaru et al 9 tried to decompose CO 2 to CO by ac glow discharge and gave a decomposition mechanism. CO 2 reduction in a gas phase ͑not in a plasma phase͒ was performed by using a Cu solid polymer electrolyte composite electrode.…”

Electrochemical and chemical reactions of CO 2 with H 2 in a gas phase were studied in an attempt to synthesize hydrocarbons by plasma reactions. When plasma was fired in a CO 2 gas alone, the only product detected was CO, showing that the chemical decomposition of CO 2 is dominant in the plasma phase. When H 2 was guided into the reaction chamber, hydrocarbons such as methane (CH 4 ), ethylene (C 2 H 4 ), and ethane (C 2 H 6 ) could be produced. Hydrocarbon formation was found to be more effective on the Cu electrode than on the Fe electrode, implying that an electrode material and then the electrode reactions can also affect the plasma reaction taking place among highly excited species. Hydrocarbons were effectively formed when the flow rate of H 2 to CO 2 exceeded three, in accordance with the expected chemical formulas of hydrocarbon formation.

We developed a device that makes possible the normal generation of low-temperature plasma under atmospheric pressure. For plasma generation, a radio frequency of rf (13.56 MHz) was used, for plasma gas, helium (He), and for material gases, acetylene (C2H2) and toluene (C6H5CH3) were used. As a result of measuring Fourier transform infrared (FT-IR) after adding the CO2 gas to the generated plasma, the absorption of C=O (carboxyl group) was observed around 1715 cm-1. When the flow rates of the added CO2 increased, the absorption peak increased at the same time, and we knew that this originated from the CO2 molecules.

We developed a device that makes possible the normal production of low-temperature plasma under atmospheric pressure. For plasma generation, a radio frequency of rf (13.56MHz) was used. From the Fourier transform infrared (FT-IR) analysis, the absorption peak of C=O (the carbonyl group) was observed around 1715 cm-1, and the absorption peak of CH was observed around 2950 cm-1. Of those, from the conclusion that the absorption peak of C=O was proportional to the amount of CO2 added, we discovered that the C=O carbonyl group originated from the CO2 molecules.

Reduction of Carbondioxide by AC Glow Discharge

Abstract: Reduction of Carbondioxide by AC Glow Discharge has been studied. Main product is Carbononoxide and the maximum efficiency of Carbondioxide reduction is about 160 nmol/secW. It has been shown that the simple simulation model based on rate equations can reproduce the experimental results.
