When the doping of boron has taken place into graphene network then redistribution of Π electrons that make the C-O bond stronger after the adsorption of oxygen . Basically, there are three types of boron in the graphene lattice. They are BC3, BCO2 and BC2O. The electrical conductivity of the electrode is enhanced by BC3 while the faradaic reactions on the surface of the electrode is accelerated by When the graphite is used as the starting material and the reaction is carried out at higher temperature (2000 °C), then chiefly substitutional doping of boron has taken place. On the other hand, if the starting material is GO and the reaction is conducted at lower temperature (< 1200 °C) then boron functionalised groups such as boronic as well as borinic acids and esters are obtained . The structure of B-doped graphene is schematically depicted in Fig. .
