“…In addition, small globules of metallic tin are usually found in the salt after electrolysis, indicating that no chemical reaction between tin and graphite has taken place. These results may thus explain the fact that no formation of carbon nanotubes occurs when electrolyses are carried out in lithium chloride/tin(II) chloride melts with tin(II) chloride contents above approximately 5 wt% [5,6].…”

“…Most of the studies making use of this technique have, in a rather empirical way, focused on the preparation of carbon nanotubes [1][2][3][4] and metal nanowires [5][6][7], the latter denoting carbon nanotubes that enclose a metal core of, typically, tin, lead or bismuth. Fray and coworkers [8][9][10] have started to investigate the reaction mechanism of the electrolytic conversion of graphite to carbon nanotubes and nanoparticles in molten alkali metal chlorides.…”

“…106 The filling of MWNTs with solid metals has been carried out by using several techniques, e.g., by arc discharge, 107,108 CVD of metallocenes, 109 pyrolysis of organic compounds in the presence of metal catalysts, 110 or condensed phase electrolysis. 111 Fig. 14 shows an example of a crystalline FeCo nanowire inside a MWNT.…”

The article reviews the interaction between crystalline metals and carbon nanotubes in nanocomposite systems. Starting with an introduction to the chemical interaction between metal atoms and graphitic layers, an overview of the fields of nanotechnology is given where metal-carbon interaction comes into play. The interface between metals and carbon nanotubes is of interest in junctions between nanotubes and their periphery, for example in metallic contacts for electronic devices or in metal supports for carbon nanotube components. Furthermore, metals determine the catalytic growth of carbon nanotubes. The behaviour of individual metal atoms in or on carbon nanotubes is treated as well as the interaction between crystalline metals and nanotube surfaces. Emphasis is put on the common mechanisms of metal-carbon interaction that play a role in such different fields as the electrical transport through a metal-nanotube contact or the catalytic growth of nanotubes from metal particles.

“…Thus, more and more attention has been paid to molten salt electrolysis for the preparation of CDC because of its short process, low cost, and environmental friendliness. [7][8][9][10] Actually, in the 1990s, Kroto et al [11][12][13] applied molten salt electrolysis for the formation of nano-structured porous carbon successfully. In recent years, some researchers [14][15][16][17] have also synthesized different kinds of CDC with a great deal of micropores which provide a high specic area via electrolysis of various precursors (e.g., TiC, SiC, WC and VC) in molten salts, demonstrating the feasibility of this method.…”

In this work, remelted high carbon ferromanganese was chosen as a consumable anode to produce porous carbon monolith and low carbon ferromanganese at the same time by molten salt electrolysis. During potentiostatic electrolysis, the anode fed manganese ions and iron ions into molten salts, with porous carbon left at the anode and ferromanganese deposited on the cathode. The anode residue was characterized by Xray diffraction, scanning electron microscopy, Raman spectrum and transmission electron microscopy.Results indicated that this type of porous carbon material with a high degree of graphitization has a multimodal pore system consisting of micropores, mesopores and macropores, which is hierarchical carbide derived carbon (CDC). The anode and cathode current efficiencies are estimated to be at least 92% and 80%, respectively. All results implied that it is feasible to prepare carbide derived carbon monoliths with a hierarchical pore structure and low carbon ferromanganese simultaneously by molten salt electrolysis.
