“…carbon [32], and fast heating is believed to be the cause of turbostratic stacked graphene formation upon high energy electrons bombardment. Similar conversions were observed when high energy laser was used, and turbostratic stacks of extended graphene layers formed by treating CB with high energy laser reaching temperatures as high as 4200 ºC ( Figure 5) [33].…”

“…These results indicate that the effects of electron irradiation will be dissipated at a greater depth from the surface of a target material [35]. Although turbostratic and graphitic carbons are both subjected to similar radiation damage mechanisms leading to rearrangement of sp 2 C lattice, intense local heating may further explain the formation of large CB aggregates [32,33]. As pointed by authors investigating SWNTs, e-beam heating induced carbon sublimation, leading to SWNT thickening and welding [38].…”

Carbon Black (CB) is one of the most abundantly produced carbon nanostructured materials, and approximately 70% of it is used as pigment and as reinforcing phase in rubber and plastics. Recent scientific findings report on other uses of CB that are of current interest, such as renewable energy harvesting and carbon capture. The present review focuses on the use and role of CB in renewable and environmental applications relevant to contemporary global challenges focusing specifically on clean energy. Key and recent research on the structure and chemistry of CB, including its uses as precursors to graphene quantum dots and hollow carbon spheres, is discussed in relation to renewable energy devices, electrochemical energy storage and environmental remediation. The surface chemistry of CB is closely related to that of graphitic and of turbostratic carbons through the predominant hexagonal carbon lattice from graphene fragments forming its basic structural units. Consequently, modern methods for grafting polymers and functional groups are easily translated to this abundant nanostructured material. Moreover, recent advances in electron microscopy that probe the structure of CB, and its electronic and physicochemical properties in nanocomposites revived the attention of what is wrongfully considered as a scientifically uninspiring material with limited potential for future technology breakthrough. CB has the potential to surge as a key player in renewable energy and environmental applications, meaning "When Black Turns Green".

The results of studies related to the development of synthesis, determination of formation conditions and elucidation of the mechanism of palladium–carbon catalyst action are integrated and critically analyzed. The attention is focused on Pd/NGC compositions (NGC is nanoglobular carbon). Methods for NGC preparation with an emphasis on its most common form, carbon black, are considered. The following issues are addressed: mechanisms of formation of carbon nanoglobules and their aggregates, methods of varying the size of nanoglobules, functionalization of the NGC surface to make it suitable as a support for palladium nanoparticles, views on the formation mechanism of palladium clusters and nanoparticles on the carbon support surface and effect of the structure and surface chemistry of carbon nanoglobules on the state of palladium sites in Pd/NGC compositions. The published data on selective hydrogenation of organic compounds in the presence of Pd/NGC catalytic compositions are integrated and systematized. The catalytic properties of Pd/NGC are analyzed in comparison with the properties of palladium catalysts supported on other carbon materials (activated carbon, carbon nanotubes). The influence of preparation conditions of NGC-based palladium compositions on their catalytic properties in practically important hydrogenation reactions is discussed. Promising trends for further research on the development of molecular design methods, study of the genesis of Pd/NGC compositions and extension of their applications in hydrogenation processes are considered. The bibliography includes 623 references.
