Synthesis of graphene-like nanosheets and their hydrogen adsorption capacity

Hybrids of NiCo 2 O 4 nanorods and nanobundles with graphene as promising electrode materials for supercapacitors

“…Among the numerous carbon materials, graphene with oneatom thick layer 2D structure, is newly founded and has attracted plenty of interests for its unique characters, such as chemical stability, high electrical conductivity, and large surface area [15]. These encouraging characteristics provide such new materials a wide range of potential applications [11,16].…”

Sustainable Production of Carbon Fiber: Effect of Cross-Linking in Wool Fiber on Carbon Yields and Morphologies of Derived Carbon Fiber

“…From Figure 6a, it is evident that all of the various carbonized wool fibers produced a broad diffraction peak centered at 2θ = 24.3°, indicative of the presence of an amorphous phase. 35 All of the carbon fiber samples also exhibited a low, broad peak at 2θ = 44°in their diffractograms that is assigned to the turbostratic band of disordered carbon (100). 35 Although not as sharp as that of pure carbon, the observed diffraction peaks are direct evidence for the presence of carbon in all of the carbonized wool fiber samples examined in this work.…”

Environmental applications using graphene composites: water remediation and gas adsorption

“…The rGO material with a surface area of 640 m 2 g À1 exhibited a hydrogen adsorption capacity of 1.2 wt % at 77 K and 0.1 wt% at 298 K. 155 Recently, Guo et al have shown that a hierarchical rGO material with a surface area of 1305 m 2 g À1 is capable of storing 4 wt% of hydrogen at 77 K and 1 bar. 156 The storage capacity of the material is believed to be due to the nanoporous structure as well as the high surface area, although the authors suggest that defect sites may play an important role as well.…”
