We investigated CO 2 splitting in recombining H 2 and He plasmas with ultralow electron temperatures between 0.1 and 0.4 eV. The conversion from CO 2 to CO and O 2 was observed in the ultralow-temperature plasmas. Since the rate coefficients of dissociation of CO 2 via electronic excited states are negligible at the ultralow electron temperature, the present experimental result gives us corroborative evidence of the CO 2 splitting via vibrational excited states. The rate coefficient of the CO 2 splitting, which was evaluated from the temporal variation of the CO 2 density, decreased clearly with the electron temperature. In addition, the rate coefficient observed in the ionizing H 2 plasma with an electron temperature of 4 eV was one order of magnitude smaller than that observed in the recombining plasmas. It has been shown that the CO 2 splitting via vibrational excited states has a larger rate coefficient than that via electronic excited states.
