▎ 摘　　要

In the present manuscript, N-doped reduced grapheneoxide (rGO) has been synthesized by using an environmentally benign amino acid, glycine, as a reducing agent (N-rGOGly) under mild experimental conditions in aqueous medium and has been explored for its electrochemical behavior. It exhibited a fairly high value of specific capacitance (263 F g(-1) at 1 A g(-1)), a high energy density/power density, a high coulombic efficiency, and long cycling stability. Annealing of this sample at a mild temperature of 300 degrees C produced crystalline N-doped rGO (N-rGOGly300) with a six-fold symmetry having a "d'' spacing of 0.367 nm as was revealed by its HRTEM analysis. XPS, Raman, and C-13 NMR analyses exhibited its enhanced graphitic character which was further evidenced by its more than six times increase in conductivity (69.78 S cm(-1)) as compared to the non-annealed sample (11.4 S cm(-1)) suggesting its possible applications for the fabrication of electrical devices. Annealing though resulted in the reduction of its pseudocapacitive contribution but it exhibited appreciably higher values of C-s of 191 F g(-1) at 1 A g(-1) and other electrochemical features.
