Nitrogen Graphene: A New and Exciting Generation of Visible Light Driven Photocatalyst and Energy Storage Application.

ABSTRACT: The synthesis of nitrogen, boron, and nitrogen-boron-codoped graphenes was attained via mixing solutions of GO with urea, boric acid, and a mixture of both, respectively, followed by drying in vacuum and annealing at 900 °C for 10 h. These materials were thoroughly characterized employing XRD, TEM, FTIR, Raman, UV-vis, XPS, IPCE%, and electrical conductivity measurements. The nitrogen-doped graphene (NG) showed an excellent supercapacitor performance with a higher specific capacitance (388 F·g^-1 at 1 A·g^-1), superior stability, and a higher power density of 0.260 kW kg^-1. This was mainly due to the designated N types of doping and most importantly N-O bonds and to lowering charge transfer and equivalent series resistances. The NG also indicated the highest
