Hierarchical Bimetallic Electrocatalyst with Amorphous SnO Layer for Highly Efficient Electroreduction of CO₂

Renewable electricity‐driven reduction of CO 2 into value‐added chemicals has been recognized as a promising sustainable energy conversion method to achieve carbon‐neutrality. Although Sn‐based catalysts show excellent selectivity towards CO and HCOOH in CO 2 reduction, the reaction activity, i. e. current density, remains quite low (<100 mA cm −2 ). Herein, a hierarchical bimetallic electrocatalyst consisting of Cu foam‐supported bundle‐like...
