Abstract: The CNx nanotubes films were fabricated by pyrolyzing ethylenediamine on Ni substrates at 860℃. The growth of CNx nanotubes on Ni substrates pretreated in different conditions was investigated. It is found that the Ni substrates pretreated in different conditions have different catalytic effects on the growth of CNx nanotubes, and the CNx nanotubes with "bamboo-like" structure grow preferentially on the Ni substrate dipped in HF for 10 min and followed by ultrasonically cleaned in ethanol.

Key words: Ni substrates, CNx nanotubes, thermal decomposition, Raman spectra
