Title:
REDUCTION CATALYST USING GRAPHITIC FRUSTRATED LEWIS ACID-BASE PAIR (GFLP), AND REDUCTION SYSTEM USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/045816
Kind Code:
A1
Abstract:
The present invention relates to a N2 reduction catalyst using a graphitic frustrated Lewis acid-base pair (GFLP) and, more specifically, to a high-performance and high-durability catalyst capable of synthesizing clean ammonia (NH3) by inducing a multi active site in an N2 molecule. In addition, the present invention relates to a battery system for reducing carbon dioxide in seawater by using a GFLP catalyst and, more specifically, to a battery system capable of reducing carbon dioxide dissolved in seawater to multi-carbon compounds such as ethanol and propanol, and increasing pH to thereby prevent seawater acidification.
