Abstract: Disclosed is a method for manufacturing a photocatalytic filter for air purification. The present manufacturing method comprises the steps of: oxidizing a titanium metal to obtain a nanostructured titanium dioxide (TiO2); adding the nanostructured titanium dioxide to an acidic fluorine-containing solution to allow a reaction to occur therebetween for a predetermined period of time; and, after treatment in the acidic fluorine-containing solution, performing heat treatment on the nanostructured titanium dioxide.

Abstract: An air conditioning device is disclosed. The present air conditioning device comprises: a photocatalytic filter including a space through which air can pass and having a transition metal oxide formed in a nanotube form on the surface thereof, the transition metal oxide removing gases included in the air and including at least one of TiO2, ZnO, NiO, and WO3; and a light source for emitting light to the photocatalytic filter.
