On-Surface Modification of Copper Cathodes by Copper(I)-Catalyzed Azide Alkyne Cycloaddition and CO2 Reduction in Organic Environments

Organic structures were introduced onto copper cathodes to induce changes to the electrocatalytic CO2 reduction activity. Poorly soluble organic polymers were distributed onto the copper surface as a thin layer, by polymerizing monomeric precursors via a copper(I)-catalyzed azide alkyne cycloaddition (CuAAC) activated by anodization of the copper substrate. The resulting structure possesses copper surface atoms that are accessible to participate...
