Carbon Dioxide Electroreduction: Orbital Interactions in Bi‐Sn Bimetallic Electrocatalysts for Highly Selective Electrochemical CO 2 Reduction toward Formate Production (Adv. Energy Mater. 31/2018)

Abstract

In article number 1802427, Zhengyu Bai, Zhongwei Chen, and co‐workers reveal orbital interactions of Bi‐Sn nanostructures, leading to the electrocatalytic conversion of CO 2 to formate with high selectivity, activity, and durability. This is attributed to the electronic states of Sn upshifting away from the Fermi level due to the coupling with Bi, making the HCOO* intermediate adsorb more favorably on Bi‐Sn than on pure Sn surfaces. This study provides sub‐atomic level insights into bimetallic catalyst development for highly selective CO 2 reduction.
