Simultaneous on-site production of hydrogen peroxide and nitrogen oxides from air and water in a low power flowing liquid film plasma discharge for use in agriculture

A method comprising:

• injecting a mixture comprising liquid water and a gas, into at least one electrically-conductive inlet capillary tube of a continuously-flowing plasma reactor to generate a flowing liquid film region on one or more internal walls of the continuously-flowing plasma reactor with a gas stream flowing through the flowing liquid film region;
• propagating a plasma discharge along the flowing liquid film region from the at least one electrically-conductive inlet capillary tube to at least one electrically-conductive outlet capillary tube at an opposing end of the continuously-flowing plasma reactor;
• dissociating the liquid water in the plasma discharge to form a plurality of dissociation products;
• producing hydrogen peroxide and nitrogen oxides from the plurality of dissociation products;
• dissolving the hydrogen peroxide and the nitrogen oxides into the flowing liquid film region;
• and
• recovering at least a portion of the hydrogen peroxide and the nitrogen oxides from the at least one electrically conductive outlet capillary tube.
