摘要：Sound-wave irradiation on the acceleration of the decomposition of carbon dioxide（CO2） and the conversion of methane （CH4） in a DC discharge field were investigated. Owing tosound-wave irradiation, an expanded streamer in a fan shape was observed, and changes ofreaction rate and product yield were evaluated. In the CO2 feed system, CO2 conversionincreased in proportion to an increase in the sound pressure, and the reaction rate of CO2 withsound-wave irradiation （1.8 kPa） was reached to approximately twice that for no sound-waveirradiation. In the CH4 feed system, an increase of conversion and slightly change of productdistribution were observed. These results indicate the improvement in the reaction probabilitydue to expansion of the discharge space and the increased vibration of charged particles.
