Hybrid Enzyme‐Electrocatalyst Cascade Modified Gas‐Diffusion Electrodes for Methanol Formation from Carbon Dioxide

Angewandte Chemie International Edition, Volume 64, Issue 12, March 17, 2025.
Towards the development of technologies for the conversion of excess atmospheric CO2, a hybrid electrocatalytic/bioelectrocatalytic system combining an inorganic catalyst with a bienzymatic cascade for CO2 electroreduction to methanol is presented. The Ag‐Bi2O3 electrocatalyst enables the selective conversion of CO2 to formate. The generated formate is

Enzymatic Bioelectrocatalysis for Enzymology Applications

ChemElectroChem, 2020
AbstractEnzymatic biosensors are commonly used to evaluate the concentration of individual analytes in samples (e. g., glucose in blood, lactate in sweat, etc.), where the working electrode utilizes an enzyme (a “bioelectrode”) as the chemically selective agent for electrochemical analyses.
