Anode is a graphite rod which projects centrally up through the base of the cell. Cathode is a ring of iron, which surrounds the anode. The anode and cathode are separated from each other by a cylindrical steel gauze diaphragm so that Na and Cl 2 are kept apart. A bell like hood is submerged over the anode.
Graphitic carbon nitride g-C3 N 4 is a conjugated polymer having a graphite-like structure, with fragile van der Waals forces between the layers and with every layer having strong C N bonding. Pristine g-C 3 N 4 shows less effectiveness in visible light owing to the wide bandgap and less specific surface.

This plasma-based process is analogous to the more familiar electroplating process in a liquid medium. The fullerenes and CNTs are formed by plasma arcing of carbonaceous materials, particularly graphite. The fullerenes or carbon nanotubes appear in the soot that is formed, while the CNTs are deposited on the opposing electrode.
