Title:
NITROGEN FIXATION DEVICE AND METHOD USING LOW-TEMPERATURE JET FLOW PLASMA COUPLED WITH MONATOMIC CATALYSIS
Document Type and Number:
WIPO Patent Application WO/2021/077730
Kind Code:
A1
Abstract:
Disclosed are a nitrogen fixation device and method using low-temperature jet flow plasma coupled with monatomic catalysis. The nitrogen fixation device comprises an electrochemical workstation, a plasma power supply, an H-type electrolytic cell and a jet flow plasma reactor. The method involves firstly preparing a transition metal monatomic catalyst, and thus preparing a working electrode of the H-type electrolytic cell; directly introducing air, nitrogen, or a mixed gas of oxygen and nitrogen into the jet flow plasma reactor, turning on the plasma power supply to achieve a stable discharge of jet flow plasma, and after the jet flow plasma reactor is discharged for 10 minutes, turning off the plasma power supply; and transferring the reaction liquid after discharge into the H-type electrolytic cell, finally turning on the electrochemical workstation to perform an electrochemical catalytic process for 30 min, and collecting a solution containing NH4
+ after the reaction in the H-type electrolytic cell. The present invention is high in efficiency and environmentally friendly, and combines plasma discharge and an electrochemical catalytic reaction, wherein a monatomic catalyst is beneficial to the improvement of the yield and reaction rate of ammonia synthesis.
