“…From the literature [21][22][23][24][25][26][27][28], N1s BEs of carbon nitride formed on solid carbon materials were found to be around 398 and 401 eV. The shift of BE in this investigation is ascribed to the different chemical environments for nitrogen atoms in various compounds and the relaxation effect in the measurement process [29][30][31]. According to the literature [24][25][26][27][32][33][34], p1 can be attributed to the tetrahedral C-N bonding with C in sp 3 hybridization and N in sp 2 hybridization states.…”

“…NCNTs have also been prepared by various post-treatment methods [41,42]. For instance, Nagaiah et al [41] synthesized NCNTs by post-thermal treating oxidized CNTs with ammonia and used the resultant NCNTs as efficient catalysts for ORR in alkaline medium.…”

Nitrogen-doped carbon materials, including nitrogen-doped carbon nanotubes (NCNTs) and nitrogen-doped graphene (NG), have attracted increasing attention for oxygen reduction reaction (ORR) in metal-air batteries and fuel cell applications, due to their optimal properties including excellent electronic conductivity, 4e − transfer and superb mechanical properties. Here, the recent progress of NCNTs-and NG-based catalysts for ORR is reviewed. Firstly, the general preparation routes of these two N-doped carbon-allotropes are introduced briefly, and then a special emphasis is placed on the developments of both NCNTs and NG as promising metal-free catalysts and/or catalyst support materials for ORR. All these efficient ORR electrocatalysts feature a low cost, high durability and excellent performance, and are thus the key factors in accelerating the widespread commercialization of metal-air battery and fuel cell technologies.

“…The carbon element was detected besides a small amount of oxygen, iron and Mo, which shows good consistency with the EDS results. The typical spectra of core-level C 1s peaks are shown in figure 4, where no obvious shoulder associated with CO type bonds can be found [13,14]. Meanwhile, the intensities of all the peaks become stronger with the increase in temperature from 200 to 600 • C.…”

One-dimensional tilted carbon nanorod arrays were synthesized on molybdenum substrates by using the catalyst-assisted oblique angle deposition technique. The structures of the one-dimensional tilted carbon nanorods evolve with substrate temperatures, but otherwise identical growth conditions. The crystallographic structures, chemical compositions and bond structures of the tilted carbon nanorods were investigated by using x-ray diffraction, energy dispersive x-ray spectroscopy, x-ray photoelectron spectroscopy and Raman scattering spectroscopy. The cross-sectional SEM image showed that multilayered tilted carbon nanorods were also obtained. The electron field emission (FE) behaviours of the obtained one-dimensional carbon tilted nanorod arrays were greatly improved with the increase in substrate temperature. Meanwhile, the sample with multiple layers of carbon tilted nanorods exhibits better FE behaviours than those with single layer.
