NBEXP0012

=NBEXP0012 — TEM of NTU Graphene/TiO2=

=Objective=

To obtain high-resolution TEM images of graphene flakes with TiO2 on the surface to show that the UV reduction process binds the TiO2 to the graphene.

=Procedure=

Deposit G/TiO2 solution on carbon-coated TEM grid.

Some image processing applied — noise reduction and levels adjustment.

=Results=

=Discussion=

Images clearly show graphene flake covered in dots approximately 10nm in diameter. Very likely TIO2 particles although is impossible to prove with TEM. (TiO2 particle diameter approx 7nm.)

=Conclusion=
