Abstract
The interfacial charge transfer phenomenon between atomic layer deposition (ALD) TiO2 and graphene substrate was investigated. A significant photocatalytic enhancement of TiO2 quantum dots/graphene hybrid nanocomposite over P25 TiO2 and TiO2 ALD film/graphene was observed. A control experiment with a conformal Al2O3 ALD film between ALD TiO2 film and graphene substrates provides direct evidences for this photocatalytic enhancement.
