Ni single atoms supported on hierarchically porous carbonized wood with highly active Ni–N₄sites as a self-supported electrode for superior CO₂electroreduction

Abstract

A self-supported single-atom electrocatalyst was developed by anchoring Ni single atoms on porous N-doped carbonized wood (Ni SAs-NCW), showing a high performance in CO 2 electroreduction and potential to be integrated into the flow cell system.
