Abstract: Disclosed is a catalyst filter, which includes a catalyst support and a nano metallic catalyst sprayed to a surface of the catalyst support. The catalyst filter uses catalyst slurry prepared by using a particulate catalyst, in which a small amount of nano metallic catalyst exhibiting a catalyst performance is sprayed to a surface of the catalyst support, different from an existing patent technique in which catalyst particles are formed and prepared as a support to consume a large amount of catalyst. Therefore, the specific surface area of the catalyst filter is not smaller than the specific surface area of the nano catalyst particles, and thus the catalyst filter may effectively remove and decompose ultra-low concentration gas-state contaminants in an indoor air.

Abstract: Disclosed is an apparatus for decomposing low-concentration volatile organic compounds, which includes: an adsorption unit configured to adsorb a volatile organic compound; a heated air supply unit configured to supply a heated air to the adsorption unit; an oxidation decomposing catalyst unit configured to decompose a volatile organic compound detached from the adsorption unit; and an ozone supply unit configured to supply an ozone to the oxidation decomposing catalyst unit. The apparatus may maximize an exchange cycle semi-permanently by adsorbing low-concentration VOC under a high-flow condition and then detaching VOC within a short time and also by recycling an adsorption filter. In addition, the apparatus may effectively decompose VOC substances detached by a low flow into carbon dioxide and water under a condition with most excellent oxidation decomposition efficiency by using an oxidation decomposing catalyst filter.
