“…The strong C (0 0 2) peak shows the graphitic carbon at 2θ (CuKα) of 23.1°, due to the hexagonal graphite type structure, demonstrating the turbostratic carbon structure with randomly oriented graphitic carbon layers [14]. Moreover, the peak around 44.3°is due to the formation of a higher degree of intralayer condensation, which should greatly improve the electrical conductivity [15]. In addition, this may be assigned to the (1 0) bidimensional planes [16].…”

There is a general consensus to develop renewable energy storage and conversion technologies to replace fossil fuel energy for sustainable development. Currently, the development of high performance energy storage and conversion devices is an important step on the road to alternative energy technologies. With a special focus on the upgradation of waste to valuable energy, this paper presents an effective synthetic method that utilizes waste newspapers as the precursor to prepare the activated carbon electrodes by the pyrolysis and chemical activation processes. The amorphous nature and surface morphology of the carbon samples were confirmed by XRD and SEM analysis, respectively. Activated waste newspaper carbon (AWNP) showed good electrochemical properties at 800°C and its specific capacitance at a scan rate of 2 mV/s was found to be 380 F/g. It is important to mention that the source of the raw material is cost effective and suitable for green technology.

“…1000°C) gave rise to dense nitrogendoped carbon materials. [18] To explore the factors responsible for the formation of precipitate during the reaction of DCA ILs with nitric acid, a set of experiments was performed in which various DCA ILs were mixed in bulk with aqueous HNO 3 (10 %vol). As a result of the lower concentration of components, the reaction was much slower and no ignition occurred.…”

“…The more pronounced peak at 43.6°, however, points to the formation of a higher degree of interlayer condensation for the higher-temperature materials [13]. The results of the comparison of ILC-500 °C, ILC-700 °C and ILC-900 °C revealed also that the synthesis at higher temperature induces less decrements in crystallinity with a higher graphitization.…”

“…As the precursors are liquids at room temperature, they can be also easily incorporated into porous templates, avoiding any high pressure techniques. Porous nitrogen doped carbons generated from these precursors do indeed show a structural inversion of the template structure, thus enabling perfect nano-casting and structural control [13][14][15][16][17].…”

Nitrogen (N)-doped ordered mesoporous carbons (OMCs) with a dual transition metal system were synthesized as non-Pt catalysts for the ORR. The highly nitrogen doped OMCs were prepared by the precursor of ionic liquid (3-methyl-1-butylpyridine dicyanamide) for N/C species and a mesoporous silica template for the physical structure. Mostly, N-doped carbons are promoted by a single transition metal to improve catalytic activity for ORR in PEMFCs. In this study, our N-doped mesoporous carbons were promoted by the dual transition metals of iron and cobalt (Fe, Co), which were incorporated into the N-doped carbons lattice by subsequently heat treatments. All the prepared carbons were characterized by via transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). To evaluate the activities of synthesized doped carbons, linear sweep was recorded in an acidic solution to compare the ORR catalytic activities values for the use in the PEMFC system. The dual transition metal promotion improved the ORR activity compared with the single transition metal promotion, due to the increase in the quaternary nitrogen species from the structural change by the dual metals. The effect of different ratio of the dual metals into the N doped carbon were examined to evaluate the activities of the oxygen reduction reaction.
