Enhancement of electrocatalytic CO 2 performance by different components of Cu-based bimetallic MOFs

Cu-based catalysts have been promising materials for electrocatalytic reduction of carbon dioxide into C 2+ products. However, the low selectivity of Cu-based catalysts for a single C 2+ product limits their application. Herein, this work presents a strategy to modify the coordination environment of...

Description
Summary:Cu-based catalysts have been promising materials for electrocatalytic reduction of carbon dioxide into C 2+ products. However, the low selectivity of Cu-based catalysts for a single C 2+ product limits their application. Herein, this work presents a strategy to modify the coordination environment of Cu-based MOF catalysts through the introduction of different doping atoms, aiming to improve the selectivity towards ethanol products. The CuIn-BTC-DBD catalyst exhibits an ethanol FE of 87% with a partial current density of −17 mA cm −2 at −1.4 V vs. RHE. Through experimental investigations, we reveal the modulation of the coordination environment of Cu-based MOFs through the doping of In atoms. This strategy improves the selectivity for ethanol products. This study provides a new approach to designing bimetallic Cu-based MOF electrocatalysts with high efficiency, mild conditions, and stable CO 2 RR to ethanol products.
