Laccase-Catalyzed Bioelectrochemical Oxidation of Water Assisted with Visible Light
Here we present the modification of fluorinated tin oxide electrodes with In2S3, an n-type semiconductor chalcogenide that absorbs visible light (λ ≤600 nm), and its further use as an active scaffold for laccase-catalyzed oxidation of water. Illumination of an FTO-In2S3- laccase electrode yields O2...

| Summary: | Here we present the modification of fluorinated tin oxide electrodes with In2S3, an n-type semiconductor chalcogenide that absorbs visible light (λ ≤600 nm), and its further use as an active scaffold for laccase-catalyzed oxidation of water. Illumination of an FTO-In2S3- laccase electrode yields O2 production at much lower applied potential in comparison to the previous example using the same laccase, where only electric energy was applied. The present system allows a diversification of the energy applied to accomplish the water splitting, taking a portion of it from the sun. This work is the first example where an enzyme other than PSII has been used in combination with visible light to biocatalyze O2 evolution. |
