Synthesis of aligned carbon nanotubes from waste chicken fat using thermal chemical vapour deposition method for field emission devices (IR)

This study aimed to synthesise carbon nanotubes (CNTs) from waste chicken fat as a carbon precursor and ferrocene as a catalyst. The method used in this study was thermal chemical vapour deposition. Several parametric studies were conducted to optimise the growth of CNTs from waste chicken fat. A ne...
