4.4 Molten Salt Preparation of Metal-Filled Carbon Nanostructures

Fig. 4.12 a Modified experimental setup employed for the large-scale production of Sn-containing
carbon nanomaterials in the LiCl melt, enabling the continuous introduction of SnCl 2 pellets into
the melt through the alumina tube shown in the figure at different intervals during the electrolysis
process. b Time variation of the potential measured between either the graphite anode and the
graphite cathode, and a Mo pseudo-reference electrode immersed in the melt. The waves observed
in the profiles are due to the interruption caused by the addition of SnCl 2 pellets into the molten
salt during the electrolysis. c The graphite electrode used as the cathode before and after being used
as cathode in the process for 20 min and 2 h. (c) also shows the graphite crucible filled with Sn–C
nanostructures at the end of the molten salt process, reproduced from Ref. [36], copyright 2019,

areas exhibit the presence of the C K- and Sn M4,5-shell ionization edges at around
24 and 27 eV, respectively. The results verify the core–shell morphology of Sn–C
nanostructures formed.
4.5 Molten Salt Preparation of Interconnected
Graphene—Carbon Nanoscrolls
Cathodic erosion of graphite cathodes can be employed as a facile and scalable
approach to produce high-quality carbon nanostructures consisting of interconnected
networks of graphene nanosheets and nanoscrolls with a hierarchical morphology
