  • Carbonnitride nanotubes with nano-sized pores on their stems, their preparation method and control method of size and quantity of pore thereof
    Publication number: 20100015031
    Abstract: Disclosed are carbon nitride (C1-xNx) nanotubes with nano-sized pores on their stems, their preparation method and control method of size and quantity of pores thereof. The present invention further has an object of providing the C1-xNx nanotube with pores having the size of not more than 1 nm over structure of the nanotube and a method for preparing the same. Another object of the present invention is to provide the control method of the size and quantity of pores with size of not more than 1 nm in the preparation of the C1-xNx nanotube with the pores over structure of the nanotube. The present invention can produce the C1-xNx nanotube with nano-sized pores by reacting hydrocarbon gas and nitrogen gas through plasma CVD in the presence of metal catalyst particles, wherein x ranges from 0.001 to 0.2.
