Title:
CuDATA CATALYST FOR NITRATE ELECTROREDUCTION TO GENERATE AMMONIA
Document Type and Number:
WIPO Patent Application WO/2023/231551
Kind Code:
A1
Abstract:
The subject invention pertains to a system for the electrochemical conversion of nitrate to ammonia. The electrolysis is carried out using a cell with a working electrode having a CuDATA molecular catalyst absorbed on carbon black. The system is effective for the conversion of waste nitrate solutions to ammonia. The conversion occurs with a high faraday efficiency of about 98%.
