This work reports the synthesis of nitrogen-doped graphene (NG) in one step by the solvothermal method, obtaining small nitrogen graphene sheets.XPS reveals that pyridinic nitrogen groups have a higher proportion than pyrrolytic, graphitic and oxide nitrogen in NG. The NG material stands out to have a higher conductivity than graphene oxide (GO) and reduced graphene (RG). The NG material stands out to have a higher conductivity than graphene oxide and graphene nitrogen. The nitrogen-doped graphene sheets were employed in the electrochemical determination of glucose through the cathodic redissolution technique. Glucose quantification was carried out at pH 7 with a sensitivity of 1.3767 mu A mu M-1 in a range of 0 to 100 mu M. The glucose determination with nitrogen-doped graphene was compared with reduced graphene (RG) and graphene oxide (GO) to evaluate the nitrogen effect.
