Abstract

Carbon dots (CDs) sensitized TiO₂ was synthesised for water splitting. The resultant photoanode showed an activity that was five times higher than that of TiO₂ under the visible light irradiation, which results from the CDs having strong absorption ability under the visible light irradiation.
