Title:
AMMONIA PRODUCTION METHOD AND AMMONIA PRODUCTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/034928
Kind Code:
A1
Abstract:
[Problem] To produce ammonia electrochemically. [Solution] This ammonia production method is a method for producing ammonia from nitrogen molecules, by supplying electrons from a power source, protons from a proton source, and nitrogen molecules from a means for supplying nitrogen gas, in the presence of a molecular catalyst and a solid catalyst at the cathode of a production apparatus that performs electrolysis. Regarding the molecular catalyst and the solid catalyst, bis(cyclopentadienyl)titanium dichloride, for example, is used as the molecular catalyst, and a metal catalyst, an oxide catalyst, or a combination thereof is used as the solid catalyst.
