Bimetallic AgCu-BTC MOF Boosts CO₂ Reduction in Zero-Gap Configuration

The potential of the reduction of CO2 in humidified gas phase was evaluated in a zero-gap configuration for bimetallic MOF electrocatalysts (AgCu-BTC). MOF electrocatalysts are very interesting materials for CO2 conversion technologies, due to their unique structural and catalytic properties. However, most MOFs have shown limited stability in liquid electrolytes (such as bicarbonate solution) during electrochemical CO2 reduction. By employing AgCu-BTC MOFs in the gas phase and in a zero-gap configuration, the contact (time) of the MOF electrocatalyst with a bicarbonate electrolyte solution was eliminated and the electrochemical performance of the bimetallic AgCu electrocatalysts was assessed in humid CO2 gas phase and as a function of varying humidity levels.
