“Living electrode” as a long-lived photoconverter for biophotolysis of water

Abstract

Living blue-green algae (Mastigocladus laminosus), immobilized on an SnO(2) optically transparent electrode with calcium alginate, functioned as an anodic photoelectrode on continuous illumination for periods of time adequate for use in a conventional electrochemical cell. This "living electrode" shows promise of use as a long-lived photoconverter of solar radiant energy to electric energy and as a suitable replacement for unstable chloroplast systems.
