Synthesis and characterization of carbon fibrils formed by stacking graphite sheets of nanometer thickness
Abstract.
Carbon fibrils with length of 2–3 lm formed by stacking graphite sheets of 10–40 nm in thickness along the h001i direction were prepared by pyrolysis of tetrahydrofuran at 600 C in the existence of metallic nickel. The spacing of adjacent sheets concentrated on 3.8 nm and 50 nm. Metallic nickel played a catalytic role in the formation of carbon fibrils, and a possible formation process was proposed.
