    摘要: Disclosed are an apparatus and a method for manufacturing composite nanoparticles. The apparatus comprises: a first precursor supply unit vaporizing a first precursor and supplying it to a reaction unit; a second precursor supply unit vaporizing a second precursor and supplying it to the reaction unit; the reaction unit producing composite nanoparticles by reacting the vaporized first precursor with the vaporized second precursor; an oxygen supply line supplying an oxygen source to the reaction unit; and a collection unit collecting the composite nanoparticles produced by the reaction unit. Since gas phase synthesis occurs in different stages using the U-shaped reaction chamber, aggregation is prevented and composite nanoparticles of uniform size and high specific surface area can be produced easily.

    摘要: Provided is a method for preparing a vanadia-titania catalyst, comprising: vaporizing a titanium precursor; conveying the vaporized titanium precursor to a reaction unit together with an oxygen supplying source; reacting the vaporized titanium precursor conveyed to the reaction unit with the oxygen supplying source to produce titania particles; condensing the titania particles, collecting and recovering them; mixing the recovered titania particles with a vanadium precursor solution; drying the mixture of the titania particles with the vanadium precursor solution; and calcining the dried mixture under oxygen atmosphere or air. Provided also is a vanadia-titania catalyst obtained by the method. In the vanadia-titania catalyst, titania particles (carriers) are prepared by chemical vapor condensation, and then vanadia is supported on the titania particles (carriers) through impregnation and calcining. Therefore, the vanadia-titania catalyst has a large specific surface area, uniform and fine nano-scaled size, and high dispersibility, thereby providing excellent nitrogen oxide removal efficiency, particularly in a low temperature range of 200° C.-250° C.
