Linear control of the oxidation level on graphene oxide sheets using the cyclic atomic layer reduction technique.

Precise control of the oxidation level on graphene oxide (GO) sheets is still a big challenge. This work demonstrates a linear control of the surface oxidation level on GO sheets via an atomic layer reduction (ALR) technique at 100 and 150 °C. The oxygen stripping rate during ALR cycling was assessed at different operating temperatures: 0.
