Carbon nanofibers with various morphologies were synthesized by the catalytic pyrolysis of acetylene using nickel catalyst nanoparticles at different reaction temperatures. Experimental results demonstrate that temperature is a critical parameter for controlling the size and morphology of carbon fibers. Twin coiled fibers and linearly bifurcating fibers emanating from nickel particles were formed at 400 °C; whereas, only linear carbon nanofibers were obtained at reaction temperatures of 450 °C, 500 °C, and 550 °C. At low temperatures, nickel nanoparticles remain in the middle of two fibers, while nickel particles are positioned at one end of the linear fibers at high temperatures.
