A visible-light driven electrochemical biofuel cell with the function of CO₂conversion to formic acid: coupled thylakoid from microalgae and biocatalyst immobilized electrodes

Abstract

A new visible-light driven electrochemical biofuel cell consisting of the thylakoid membrane of microalgae immobilized on a TiO₂layer electrode as a photoanode, a formate dehydrogenase/viologen co-immobilized electrode as a cathode, and a CO₂-saturated buffer solution as the redox electrolyte, was developed.
