“…Identified B surface groups show that B prefers basal plane sites. On the other hand, N prefers pyrrolic/pyridone type moiety, which is characteristic for edge plane sites [13]. The results regarding P suggest that it dislikes surface sites, being found in the bulk and potentially inside the pore walls.…”

“…Specific roles for different heteroatom moieties have been put forward providing insights into the surface processes involved in ORR. N-doping has been studied extensively [13], and the role of nitrogen content, specific surface groups, and charge delocalization are fairly well understood [14][15][16][17][18][19][20]. However, doping with other heteroatoms, namely boron [12,21,22], phosphorus [23][24][25][26], and sulfur, [27,28] has been employed just recently, expecting to have the same or similar effect on the activity of these materials and is not explored thoroughly yet.…”

“…The other problem arises due to the fact that different doping levels can be achieved with different dopants. Carbon materials can be heavily doped with N, reaching even more than 10-15 at% [13]. On the other hand, doping levels of P, B, and other heteroatoms are usually much lower, typically a few at% [12,31,32].…”

In order to elucidate the role of B, N, and P dopants in carbon materials on the kinetics of oxygen reduction reaction (ORR) and to provide a fair comparison of the effects of each dopant, a series of ordered mesoporous carbons (OMCs) with low concentration of heteroatoms (< 1 at%) has been prepared. Doped OMCs were characterized using X-ray photoelectron spectroscopy (XPS), inductively coupled plasma optical emission spectroscopy (ICP-OES), Raman spectroscopy, X-ray powder diffraction (XRD), and N-2 physisorption measurements. Comparative study of the ORR activity of these materials in alkaline solution was performed using rotating disk electrode voltammetry. The experiments evidenced that, compared to non-doped OMC, charge transfer kinetics was improved independently on the nature of the heteroatom. The decrease of the ORR overvoltage and the increase of the mass activity upon doping are similar for B and P and less prominent for N. On the other hand, OMCs doped with low levels of B and N were found to be selective for O-2 reduction to peroxide, while for P-doped OMCs, the apparent number of electrons consumed per O-2 molecule was up to 3.1. Experimental measurements were complemented by density functional theory (DFT) calculations

“…1-D nitrogen-containing CNTs (1-D NCNSs) have emerged in the past two decades as exceptionally promising nanomaterials due to their unique physical and chemical properties, which enable a broad range of applications in various fields of modern technology. 193 All these CNTs or NCNS materials can be used in the field of EMs in the following ways: (1) functionalized with polymeric binders, (2) coupled with pyrotechnics, (3) used as carriers of combustion catalysts, (4) combined with metal fuels and (5) functionalized with energetic moieties/groups. CNTs functionalized with polymeric binders.…”

Therefore, it is necessary to develop highperformance energy storage devices for facilitating the effective utilization of intermittent renewable energy sources. [7][8][9] Among varieties of electrochemical energy storage devices, supercapacitors (known as electrochemical capacitors) [10,11] and some rechargeable batteries (lithium-ion batteries (LIBs), lithiumsulfur (Li-S) batteries, and metal-O 2 batteries) [12][13][14][15] are at the frontier, because they can transport high power and store high energy. Nowadays, they play an indispensable role in our daily life by powering numerous portable electronic devices (e.g., cell phones and laptops), hybrid electric vehicles, and large-scale electrical grids. [16][17][18][19] It is well accepted that the performance of energy storage devices mainly depended on their electrode materials. [20,21] Owing to the advantages of large surface area, light weight, good electrical conductivity, and high thermal/ chemical stability, carbon materials have been considered as the most important electrode materials of supercapacitors and rechargeable batteries [8,20,21] Hence, various nanostructured carbons, such as carbon/graphene quantum dots, [22,23] carbon nanofiber (CNFs), [16,24] carbon nanotubes (CNTs), [13,25] graphene [26][27][28][29][30][31][32] carbon nanosheets, [33,34] 3D carbon nanostructures, [35][36][37] and porous carbon, [38,39] have gained great attention. Among these materials, 3D carbon nanomaterials have some advantages. The interlinked architecture not only shortens transport distances for ions in the well-interconnected wall structure, but also provides a continuous pathway endowing for the fast electron transport. [40] Moreover, the structural interconnectivities guarantee higher electrical conductivity and better mechanical stability. [36,41] Thereby, the design and fabrication of various 3D carbonbased nanostructures, including carbon nanotube networks, graphene gels, graphene foams, and 3D CNFs, have been intensively investigated.Over the past few years, there are many reviews summarizing the progress of fabricating 3D carbon-based nanomaterials. For example, Schneider et al. overviewed the recent advance in the synthesis of 3D arranged carbon nanotube architectures. [42] Li et al. reviewed the carbon-based 3D nanostructures for supercapacitors. [36] Cao and Gui et al. comprehensively reviewed the recent progress in synthesis, properties, and energy applications of CNT sponges, aerogels, and hierarchical composites. [43] The development of high-performance electrochemical energy storage devices is critical for addressing energy crises and environmental pollution.
