摘要

Background: Nitrogen (N)-doping in the graphene lattice is a process to tailor the physicochemicalproperties of graphene nanosheets, and explored for potential use in the various modern applications.Objective: Synthesis of N-doped graphene nanosheets via green route in contrast to the post traditionalharmful methods.Method: N-doped graphene nanosheets have been synthesized by simple solvothermal method at 180 ~(o)Cusing cow urine as a natural dopant of nitrogen.Results: Experimental results confirm that the cow urine has deoxygenated the graphene oxide to producegraphene nanosheets, and simultaneously nitrogen atoms are successfully doped into graphenelattice from cow urine. The current approach produces high yield N-doped graphene nanosheets with Ncontent ~ 3.2 at.% into the graphene lattice.Conclusion: A strikingly simple, cost effective and environmental friendly approach has been demonstratedfor the synthesis of N-doped graphene nanosheets by simple solvothermal method using cowurine as a natural dopant of N atoms. The proposed approach produces N-doped graphene nanosheets atbulk scale.
