AI Technical Summary
Existing copper-based catalysts exhibit a dominant hydrogen evolution reaction in acidic media, resulting in decreased selectivity for multi-carbon products and poor catalytic stability, making it difficult to maintain high selectivity and stability at industrial-grade current densities.
A copper-based catalyst with a core-shell structure is used, in which a copper oxide core is coated with a polymer layer and formed through in-situ polymerization. This process regulates the electronic structure and interfacial microenvironment, thereby suppressing hydrogen evolution side reactions.
It achieves high stability and high selectivity in acidic media, with a multi-carbon product selectivity of 77.8%, and is suitable for industrial-grade current densities.
