A direct charger transfer from interface to surface for the highly efficient spatial separation of electrons and holes: The construction of Ti-C bonded interfaces in TiO2-C composite as a touchstone for photocatalytic water splitting

TiO2-C composite with a Ti-C chemically bonded interface can short the charger transfer path and make a direct charger transform from interface to surface. TiO2-C composite displayed exceptional photoelectron responses compared to TiO2/C composite without Ti-C bond. The rate of visible-light driven photocatalytic water splitting for H2 generation of TiO2-C was about 12 times of TiO2/C composite.265
