(color online) Schematic illustration for the ET process and possible consumption ways (electron extraction by O2 in water, ER for electron recombination back to the CDs and EC for electron capture into TiO2 defect states) for injected electrons into TiO2 conduction band within the CD/TiO2 nanocomposites in water after being irradiated with visible light.
