Carbon nanofibres (CNFs) and carbon spheres (CSs) are successfully synthesised using coal particles (<44 micron) in solid phase. Coal and ferrocene as catalyst were fed to the reactor in the solid form. The reaction is carried out in a tubular reactor. The as‐synthesised samples have been characterised through Raman spectroscopy, X‐ray diffraction, scanning and transmission electron microscopy. The results show CNFs formed in 25–40 nm and mono dispersed CSs in 200–300 nm are amorphous. A feasible mechanism of CNFs and CSs formation from coal described here with the help of coal structure.
