Since most of the articles prefer to synthesize N doped graphene using graphene oxide as precursor, my interest is to know whether there is any method to synthesis N doped graphene (high % of N) using graphene directly. If possible kindly cite references.
Dear Prof. Ghosh,
Unfortunately I cannot reply just to your question, but probably my paper A.P. Kharitonov, Jinlong Zha, M. Dubois. Tunable hydrophylicity/hydrophobicity of fluorinated carbon nanotubes via graft polymerization of gaseous monomers. Accepted for publication. DOI: http://dx.doi.org/doi:10.1016/j.jfluchem.2015.03.006 can be interesting for you. I have grafted different monomers to graphene also but I have not yet published that data.
Best wishes
Prof. A.P. Kharitonov
Doping process at high temperature range (about 3000 °C ) and under nitrogen atmosphere in a sealed vacuum Furnace could do so.
I think Graphene oxides (GO) prepared by chemical exfoliation approaches can be regarded as O-doped graphene materials. The abundant oxygen functional groups and defects on GO can act as reactive sites for the doping of other heteroatomsTo avoid aggregation during the annealing process and ensure free gas transport.
