Supramolecular self-assembly-induced quasi-amorphization strengthens metal–support interfacial coupling for efficient CO 2 -to-CO electrocatalysis

Supramolecular self-assembly yields uniformly dispersed Ag and strongly coupled Ag–CN interfaces, enabling Ag 1.0 CN to facilitate the formation of the key intermediate *COOH and achieve ∼97% CO faradaic efficiency at low overpotential.
