| 1. A method for producing a C1-xNx nanotube with pores having nano-sized diameter comprising:
reacting 10 to 90% of hydrocarbon gas with 10 to 90% of nitrogen gas through a plasma CVD (chemical vapor deposition) in the
presence of a metal catalyst to grow the nanotube, and
controlling the pore diameter by controlling the concentration of nitrogen gas:
wherein x ranges from 0.001 to 0.2.
