Title:
CATALYST STRUCTURE FOR ELECTROCHEMICAL CO2 REDUCTION, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2021/075638
Kind Code:
A1
Abstract:
According to an aspect of the present invention, provided is a catalyst structure for electrochemical CO2 reduction. According to an embodiment of the present invention, the catalyst structure for electrochemical CO2 reduction includes: carbon nanofibers doped with nitrogen; and Cu particles dispersed on the carbon nanofibers. According to an embodiment of the present invention, at least a portion of the carbon nanofibers in regions forming interfaces with the Cu particles may have a pyridine-like arrangement structure.
