Covalently attached graphene-TiO2 hybrid nanomaterials for high efficient photocatalyst |
| 초록 |
This research reports the example of graphene and TiO2 hybrid nanomaterials synthesized by covalently conjugating TiO2 nanoparticles on graphene. In this hybrid system, graphene acts as an electron acceptor to ensure fast charge transfer to the current collector. The hybrid nanomaterials demonstrated enhanced photocatalytic activity under both visible and UV light. This enhancement in photocatalytic activity can be attributed to the high specific surface area of the graphene and the excellent dispersion of TiO2 nanoparticles on graphene surface, which provide more accessible surfaces to reagents and better light harvesting, as well as the strong interactions between the TiO2 nanoparticles and graphene resulting from the covalent attachment.This work was supported by Korea Institute for Advancement of Technology (KIAT) through the Encouragement Program for The Industries of Economic Cooperation Region.
