| titleOfInvention | Synthesis of Nitrogen-doped Titanium Dioxide Powder Using Electromagnetic Plasma Torch |
| abstract | A method for synthesizing a metal oxide nanopowder which is photocatalytically activated in the visible light region from a metal compound vapor. In particular, a method of doping nitrogen (N) simultaneously with the synthesis of titanium dioxide (TiO 2 ) nanopowder from vaporous titanium tetrachloride (TiCl 4 ) is disclosed. Titanium tetrachloride vapor decomposes in an electrically induced electromagnetic plasma and reacts with the oxidizing gas to form titanium dioxide vapor, and at the same time the metal oxide vapor reacts with nitrogen radicals in the plasma region to form nitrogen doped titanium dioxide vapor. The nitrogen-doped titanium dioxide (N-Doped TiO 2 ) nanopowder is synthesized by rapidly cooling out of the plasma region.n n n And the present invention to achieve the above object is a magnetron 10 for oscillating a typical 2.45 GHz electromagnetic wave; A power supply device 20 for supplying power to the magnetron 10; A circulator 30 which completely absorbs the reflected waves reflected by the magnetron 10 to protect the magnetron 10 and outputs electromagnetic waves oscillated from the magnetron 10; A directional coupler 40 for monitoring the magnitudes of incident and reflected waves and outputting electromagnetic waves transmitted through the circulator 30; A 3-stub tuner 50 for matching impedance to electromagnetic waves input from the directional coupler 40; A reactor 80 in which a plasma is generated by the electromagnetic waves transmitted through the 3-stub tuner 50 and the vortex gas injected from the outside, and the titanium dioxide synthesis reaction and the doping of nitrogen occur; In the reactor 80, a winch supply unit 60 for injecting a source gas necessary for the vortex gas and nitrogen-doped titanium dioxide synthesis reaction to stabilize the plasma, and a powder collector 70 for collecting powders synthesized from the reactor 80 Include.n n n n Plasma, electromagnetic wave, titanium dioxide, titanium tetrachloride, nitrogen doping, nano powder |
