The method of synthesizing carbon nanotubes gas detonation iron

The present invention belongs to the technical field synthesis of nanomaterials, there is provided a method of synthesis of iron-containing gaseous detonation of carbon nanotubes. The gaseous detonation tube sealed after evacuation, the organic iron source is added thereto, gaseous detonation tube heated to 100 ~ 180 ℃, the organic iron source is evaporated into gaseous; After the organic iron source is sufficiently evaporated into gas, the gas blast H-filled tube into the hydrocarbon fuel gas; the hydrocarbon fuel gas is acetylene or methane; gaseous detonation tube again charged oxygen until the pressure is 0.05 ~ 0.2MPa; heating was stopped, the gas detonation; detonation to be completed after cooling gaseous detonation tube, the exhaust gas, the product was collected, namely iron-containing carbon nanotubes; method of the present invention is simple, efficient, inexpensive, clean and large output.
