Preparation of N‐doped graphene powders by cyclic voltammetry and a potential application of them: Anode materials of Li‐ion batteries

Abstract: Summary Nowadays, doped graphenes are attracting much interest in the field of Li‐ion batteries since it shows higher specific capacity than widely used graphite. However, synthesis methods of doped graphenes have secondary processes that requires much energy. In this study, in situ synthesis of N‐doped graphene powders by using of cyclic voltammetric method from starting a graphite rod in nitric acid solution has been discussed for the first time in the literature. The N‐including functional groups such as ni… Show more

“…However, Gursu et al has proposed an effective and one‐step electrochemical method for the preparation of graphene‐based electrodes by cyclic voltammetry. They used the Yucel's method prepared graphene and heteroatom graphene electrodes as positive electrode materials of vanadium redox battery and they shortly discussed capacitive behaviors of these electrodes in electrochemical impedance spectroscopic (EIS) analysis . Hence, investigation of the capacitive behaviors of these one‐step prepared of graphene‐based electrodes in supercapacitor application has great importance.…”

“…Besides, such catalytic activity can be further enhanced when graphene is used as the pristine material [35,36] . Until now a variety of ways to prepared nitrogen‐doped graphene have been investigated, like chemical vapor deposition, [37] microwave irradiation, [38] thermal annealing, [39] and cyclic voltammetry [40] …”

“…[35,36] Until now a variety of ways to prepared nitrogen-doped graphene have been investigated, like chemical vapor deposition, [37] microwave irradiation, [38] thermal annealing, [39] and cyclic voltammetry. [40] In this report, we optimized the oxidation approach reported by Marcano et al [41] through the incorporation of KMnO 4 (the mass ratio of graphite to KMnO 4 is 1 : 5) and 5 : 1 mixture of H 2 SO 4 and H 3 PO 4 to improve the oxidation effect (the as-formed graphene oxide through this approach is denoted as IMGO). The environmentally friendly route coupling the glucose reduction with thermal treatment to reduce the graphene oxide promotes the reduced graphene oxide with higher deoxygenation efficiency and quality.…”

“…[26][27][28] In particular, graphene structures doped with heteroatoms such as N, S, and P atoms have shown promising results in electrochemical energy storage systems. 23,[29][30][31] While, the doping of graphene with various heteroatoms increases the network disorder in graphene, it positively affects the specic capacities for energy storage applications. 32 Doped heteroatoms entering the graphene framework create defects in the graphene structure as electron acceptors (ptype) or donors (n-type) and contribute towards electron conductivity.…”
