Sinusoidal and pulse waveforms of applied voltage were employed for CO
2
reforming of CH
4
to syngas in an atmospheric dielectric barrier discharge reactor. The discharge power of a pulse waveform was higher than that of sinusoidal waveform at the same applied voltage. The plasma reaction by a pulse waveform enhanced the conversion of CO
2
and CH
4
and the selectivity of H
2
and CO. It was confirmed that CO
2
reforming of CH
4
can be improved by the adaption of pulse-type power supply in a dielectric barrier discharge reactor immersed in an electrically insulating oil bath.
