Title:
ORGANIC-BASED ELECTROCHEMICAL SYSTEM FOR REMOVING UNREACTED AMMONIA
Document Type and Number:
WIPO Patent Application WO/2023/128244
Kind Code:
A1
Abstract:
The present invention relates to an organic-based electrochemical system for removing unreacted ammonia. More specifically, the present invention lowers, during extraction of hydrogen from ammonia, the activation energy required for an ammonia removal reaction through an organic-based electrochemical system, so that a catalytic reaction rapidly proceeds, and thus improved activity is exhibited. The present invention comprises a working electrode, a counter electrode, and a reference electrode, and an electrolyte and a support electrolyte, which connect same, and the working electrode comprises a non-noble metal-based catalyst and platinum applied to the surface thereof so that the use of noble metals is reduced by the interaction between a catalyst and a support, and thus an economic effect superior to that of a catalyst having, deposited thereon, approximately 15 times more platinum, which is a noble metal, is implemented, and the problem of high maintenance and incidental expenses of a conventional PSA method can be solved.
