Abstract: The present disclosure is related to the field of chemistry and provides methods and devices for stimulation of endothermic reactions in gas phase with high activation barriers by nanosecond pulsed electrical discharge. It can be used for, e.g., CO2 functionalization of methane, H2S dissociation, hydrogen and syngas production, for processing ammonia synthesis and dissociation, etc. Some embodiments include methods and devices associated with the stimulation of plasma chemical reactions with nanosecond pulse electric discharge in the presence of gas flow.

Abstract: A system for manufacturing a nanomaterial may include a first electrode; a second electrode spaced apart from the first electrode by a gap; and a chamber configured to enclose the first electrode, the second electrode, and a liquid. The system may also include a power supply configured to provide electrical energy to at least one of the first electrode and the second electrode; and a pump configured to cause the liquid to flow through the gap between the first electrode and the second electrode.
