PURPOSE: A manufacturing method of a nano-oxygen catalyst for removing a sick house syndrome is provided to remove volatile organic compounds such as formaldehyde, toluene, xylene, and benzene by simply coating the catalyst on the surface of an interior finishing material, and the catalyst can be used semi-permanently without the activity degradation of the catalyst which does not directly react with the other volatile organic compounds or contaminants. CONSTITUTION: A manufacturing method of a nano-oxygen catalyst for removing a sick house syndrome comprises the following steps: the first step of filling titanium tetrachloride and refined water in a ratio of 1:100 in a stainless tank at room temperature, and stirring after adding 0.20-0.39 mol of ammonia water; the second step of extracting a pure titanium dioxide solution, which is a separated lower layer, and filling the stainless tank with the solution; the third step of stirring the mixture after adding 0.23-0.35 mol of nitric acid, and stirring the mixture for 20-50 minutes after additionally adding 0.12-0.25 mol of silica sol; and the fourth step of stirring the mixture after adding 0.013-0.03 mol of acryl binder with minor portions of dispersant and EDTA. |
