“…Nyquist plots of the two electrodes from electrochemical impedance spectroscopy tests indicate an internal resistance higher for the electrode of 1212 m 2 /g (about two times higher). In [27] for microspheres with a diameter of 2-5 μm and hierarchical mesopores in a range of 3.5-60 nm, a surface area of 1320 m 2 /g and specific capacitance of 208 F/g at 0.5 A/g is reported. A 2 M H 2 SO 4 electrolyte was used.…”

“…Significantly higher specific capacitance of 455 F/g but for a surface area of 1976 m 2 /g was obtained in [30] for activated carbon derived from polyaniline after carbonization and KOH activation. Instead of a two electrode cell used in [27][28], a three electrode system was used for electrochemical characterization.…”

“…The consistent hollow cores of the hierarchically porous CC-170 were identical and strongly connected to each other. 17 TEM image of CGN-170 and CPN-170 confirmed that the Au and P nanoparticles were dispersed homogeneously and adhered to the carbon cage cores (Figures 3(c) and 3(d)). TEM of CGPN-170 revealed combined Au and P nanoparticles on the interconnected hierarchically wider hollow cores (~170 nm) of the carbon structure (Figures 3(e) and 3(f)).…”

Metal-containing carbon nanocomposites have shown significance promise in the area of energy storage, heterogeneous catalysis and material science because of their morphology and combined properties. Phosphorus-doped carbon nanocomposites with gold nanoparticles were developed by applying a simple impregnation method and metal deposition technique. Gold-phosphorus supported carbon nanocomposites with two sized (25 and 170 nm) were prepared from economical petroleum pitch residue as the carbon source using an advanced silica template method. These nanocomposites will lead to the novel applications in the field of material science with the combined properties of gold, phosphorus and carbon. The newly prepared gold phosphorus supported carbon nanocomposites were fully characterized using a range of different physicochemical techniques.

“…These features endow nanoporous carbons with potential for the applications for electrochemical capacitation, gas adsorption, catalysis, and sensing [7][8][9]. Moreover, some of them, such as carbon nanotubes [10,11], glassy carbon films [12], activated carbon [13], graphene [14] and fullerene [15], have already been used in SPME.…”

A nanoporous carbon derived from an aluminumbased metal-organic framework was deposited on stainless steel wires in a sol-gel matrix. The resulting fibers were applied to the solid-phase microextraction of the polycyclic aromatic hydrocarbons (PAHs) naphthalene, acenaphthene, fluorene, phenanthrene and anthracene from water and soil samples. The fiber was then directly inserted into the GC injector and the PAHs were quantified by GC-MS. The effects of salt addition, extraction temperature, extraction time, sample volume and desorption conditions on the extraction efficiency were optimized. A linear response to the analytes was observed in the 0.1 to 12 μg L −1 range for water samples, and in the 0.6 to 30 μg kg −1 for soil samples, with the correlation coefficients ranging from 0.9934 to 0.9985. The limits of detection ranged from 5.0 to 20 ng L −1 for water samples, and from 30 to 90 ng kg −1 for soil samples. The recoveries of spiked samples were between 72.4 and 108.0 %, and the precision, expressed as the relative standard deviations, is <12.8 %.
