Carbon, well-known from the primordial time, is known as the king of elements, owing to its usefulness and multiplicity in fields such as advanced materials and energy harvesting applications, which is indisputable. Coal is a breakable, ignitable, solid hydrocarbon fuel molded by the decay and modification of flora under high temperature, pressure, and compaction. Due to its origin, coal is a composite and assorted mineral having both organic and inorganic components. Chemical leaching of coal with aid of mineral acid, organic acid, or alkaline solutions helps to lower ash making minerals to a great level. Generally, C-NMR spectroscopy is applied for the identification of carbon atoms in different chemical environments. The transmission electron microscope image of the nanocarbon obtained from coal reveals the formation of graphene structure with hexagonal, spherical, and corn shaped carbon nanotubes. Coal by nature is an abundantly available solid fuel, and delivers most of the power requirements for the living and fiscal advancement of a country.
