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 the TA molecules effectively stabilize Cu⁺ sites, facilitating the formation of key intermediates (*COOH and *CHO) and enhancing the C–C coupling process.
