Alloying effect modulated electronic structure of Mo-doped PdIn bimetallene nanoribbons for ambient electrosynthesis of urea†

Abstract

Designing advanced catalysts for electrosynthesis of urea is of significance yet remains challenging. Herein, ultrathin two-dimensional Mo-doped PdIn bimetallene nanoribbons were synthesized via a one-pot method. Material characterization and electrochemical study revealed that the alloying effect enabled electron transfer from In to Pd and provided dual metal sites with regulated electronic structure for the adsorption and activation of NO₃⁻ and CO₂, thus facilitating the generation of key active intermediates and promoting the C–N coupling reaction.
