Growth of oriented vapor grown carbon fibers on pyrolytic carbon films without catalyst

Vapor-grown carbon fibers (VGCFs) have been of great interest to scientific and industrial communities for many years due to their unique crystalline structure as well as excellent physical and chemical properties [1, 2, 3]. They have potential applications as fillers in composites, super-high hydrogen storage materials, and good electrode materials [4, 5, 6, 7, 8]. VGCFs are usually prepared by the decomposition of hydrocarbons, such as benzene and methane, using ultra-fine transition metal particles or their alloys as a catalyst at a growth temperature of 600–1300 °C [9, 10, 11]. However, these methods sustain the disadvantage of introducing catalyst particles, which can make the synthesis process more complex, and the existence of catalyst must influence the properties of the products. Moreover, the mesoporous template or the d.c. bias was generally needed to enhance the growth of the oriented carbon nanotubes and carbon nanofibers [12, 13]. Recently, Lin et al.  prepared...
