English abstract
Here we present the modification of fluorinated tin oxide electrodes with In2S3, an n-​type semiconductor chalcogenide that absorbs visible light (λ ≤600)​, and is further use as an active scaffold for laccase-​catalyzed oxidn. of water. Illumination of an FTO-​In2S3-​laccase electrode yields O2 prodn. at much lower applied potential in comparison to the previous example using the same laccase, where only elec. 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 was used in combination with visible light to biocatalyze O2 evolution.
