Biphasic plasma microreactor and method of using the same

A plasma microreactor comprising:

• a support, made at least partially of a dielectric material, the support comprising a gas inlet, adapted to be connected to a gas reservoir, a liquid inlet, adapted to be connected to a liquid reservoir and at least a fluid outlet adapted to be connected to a receiver containing gas and/or liquid,
• a liquid microchannel in the support adapted to allow a liquid flow from the liquid inlet to the fluid outlet according to a liquid flowing direction,
• a gas channel, in the support adapted to allow a gas flow from the gas inlet to the fluid outlet according to a gas flowing direction,
• at least a ground electrode,
• at least a high voltage electrode, separated from the gas channel by the dielectric material of the support,
• wherein said ground electrode and said high voltage electrode are arranged on opposite sides of the gas channel so as to be able to create an electric field inside the gas channel,
• wherein the plasma microreactor comprises a contact zone in which the liquid microchannel and the gas channel are contiguous, so that the liquid flowing direction and the gas flowing direction are parallel in the contact zone, at least one opening being arranged between the liquid microchannel and the gas channel in the contact zone so as to form a fluid channel and to cause the liquid flow to contact the gas flow and wherein the liquid flow is retained within the liquid microchannel by capillarity action.
