Title:
AMMONIA PRODUCTION METHOD AND AMMONIA PRODUCTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/034927
Kind Code:
A1
Abstract:
[Problem] To electrochemically produce ammonia. [Solution] This method for producing ammonia involves producing ammonia from molecular nitrogen in a production apparatus for performing electrolysis by supplying electrons from a power source, protons from a proton source and molecular nitrogen from a means for supplying a nitrogen gas while in the presence of a solid catalyst and a complex in a cathode. The present invention uses, for example, a molybdenum complex represented by formula (A1) or formula (B2) as the complex, and a platinum catalyst or a platinum catalyst/gold catalyst combination as the solid catalyst.
