• To explore the potential applications of these N-CBs as catalysts and in nano-electronics.

Main Methods:

• Chemical vapor deposition under unstable conditions was employed for synthesis.
• Co/Cu films were used as substrates for growing wrinkled carbon fibers.
• Characterization involved investigating chemical functional groups, N-doping, and carbon hybridization.

Main Results:

• Nitrogen-doped carbon belt (N-CB) structures, 0.2-3.0 microns wide and 350 nm thick, were successfully assembled from wrinkled carbon fibers.
• The structures exhibit a tubular morphology with holed and wrinkled graphite layers.
• Sulphur and copper atoms were found to significantly alter the catalytic activity of cobalt, influencing carbon growth.

Conclusions:
