Optimized Copper Interfaces with Trianglamine for Enhanced Electrocatalytic CO2 Reduction

Abstract

We employ an innovative surface modification strategy using trianglamine (TA) to construct an amino-functionalized Cu-TA catalyst via in situ electrochemical reduction. The extended π-conjugation system and -NH- groups in TA molecules effectively stabilize Cu+ sites, facilitating the formation of key intermediates (*COOH, and *CHO) and enhancing the C-C coupling process.
