Bismuth oxide nanostructure supported on Cu foam as efficient electrocatalyst toward carbon dioxide electroreduction

Bismuth-based catalysts have emerged as promising materials for efficient electrochemical reduction of carbon dioxide due to their unique electronic and catalytic properties. In this work, we present a new type hybrid nanomaterials compositing partially reduced oxide Bi particle into metallic anchored on 3D network Cu foam high-performance catalyst CO2 conversion formate. electroreduction in neutral condition with high durability has remained challenging. One the main stability problems is susceptibility surface oxidation, which can cause deactivation during reactions. Under proper bismuth growth control, herein, our strategy preparing Bi/Cu demonstrated performance formate faradaic efficiency more than 90% great 50-h operation at an applied current density 50 mA cm–2 environment. The fine nanostructures resulted available active sites conductivity substrate its selectivity.
