“…[29,30] These are significantly lower than that (10.5 at %) observed with THNC. Such a changing trend of N content has also been observed in other N-doped carbon materials prepared in a similar fashion, and it is generally attributed to the sequential decomposition of the thermolabile pyrrolic N and pyridinic N + ÀO À species at relatively low pyrolysis temperatures and the degradation of more stable pyridinic N and graphitic N species at higher temperatures [31][32][33][34][35] (trace amounts of ZnCl 2 and ZnO can also be observed in the samples, as indicated by the two weak peaks at 1021.9 and 1195.8 eV). In fact, deconvolution of the N 1s peaks in Figures [19,36] Note that, in pre-pyrolysis THNC, pyrrolic N was the dominant species with no pyridinic N + ÀO À ; [37] yet after pyrolysis, graphitic N and pyridinic N became the major forms of nitrogen doping and their relative contents increased with increasing calcination temperature.…”

A synthetic method was developed for the preparation of N‐doped porous carbon through hydrothermal treatment at controlled temperatures by using glucose and dicyandiamide as precursors and ZnCl2 as an activation reagent. Nitrogen doping was quantitatively determined by using XPS measurements and identified in the forms of pyridinic, pyrrolic, graphitic, and pyridinic N+O−nitrogen atoms. Further structural analysis by using SEM, TEM, XRD, Raman, FTIR, and BET measurements showed that the N‐doped porous carbons exhibited a microcrystalline graphite structure and a high specific surface area up to 1000 m2 g−1. Electrochemical studies showed that the samples all exhibited a remarkable ORR catalytic activity in alkaline media, which was comparable to that of state‐of‐the‐art Pt/C catalysts, and the one prepared at 800 °C was found to be the best among the series with an onset potential of +0.96 V, almost complete reduction of oxygen to OH−, and superior methanol tolerance and cycling stability.

“…These core/shell nanostructures of the carbon materials are adequately synthesized by several methods [191,192], including the pyrolysis of the carbon nanofibers and the nitrogen-doped graphitic layer pyrolysis as a core and shell, respectively. The internal surfaces of these cages are freely available for the electrolytes and entrapping molecules [193]. The other synthetic methods reported are the quenching graphite rods in the aqueous NH 4 HCO 3 at 1000°C [194] and the most popular templating process.…”

Abstract:Nitrogen doping is an effective way to tailor the properties of the shaped carbon materials, including the nanotubes, nanocups, nanofibers, as well as the nanorods, and render their potential use for various applications. The common bonding configurations obtained on the N insertion is the pyridinic N and pyrrolic N, which impart the characteristic properties to these carbon materials. This review will focus on the nitrogen-doped carbon materials, the doping effect on the electrochemistry of the doped nanomaterials, and the various synthetic methods to introduce N into the carbon network. The potential applications of the N-doped materials are also reviewed on the basis of the experimental and theoretical studies in electrochemistry.

), and show excellent electrochemical properties. As an example in electrochemical applications, N-STCs were used to electrochemically detect hydrogen peroxide (H 2 O 2 ) and glucose. The results showed that the N-STCs modified glassy carbon (N-STCs/GC) electrode had much better analytical performance (lower detection limit and wider linear range) compared to the acid-treated carbon nanotubes (AO-CNTs) based GC electrode. The unique structure endows N-STCs the enhanced electrochemical performance and promising applications in electrochemical sensing.
