Abstract: The present invention relates to an aerosol spray for cleaning a drain with an excellent foam cleaning effect by spraying a drain cleaning composition to a drain hole and a drain of a sink, and the foamed cleaner can remain for a long time by spraying the drain cleaning composition in an aerosol or foam form to a sink filter, a drain hole and a drain, to maximize the cleaning effect. In addition, the present invention discloses a method for cleaning a drain of a sink comprising; (a) preparing a cleaner container comprising a first receiving part and a second receiving part in which a first agent and a second agent are received respectively; (b) mixing the first agent and the second agent each other; and (c) arranging the cleaner container in a drain inlet of a sink to inject a mixed foam cleansing agent released through an outlet of the cleaner container.

Abstract: The present invention relates to a nickel-based catalyst for oxidizing carbon monoxide, which is prepared by forming nickel oxide on the surface of a mesoporous support by one or more cycles of atomic layer deposition, and a use thereof. The nickel-based catalyst for oxidizing carbon monoxide according to the present invention is stable at high temperatures because the size of the nickel oxide particles can be restricted to nanometer scales even at high-temperature conditions. In addition, the nickel-based catalyst exhibits catalytic reactivity for oxidation of carbon monoxide even at room temperatures. Additionally, the catalytic activity, which has been deactivated after conducting the catalytic reaction, can be regenerated through annealing and increased gradually through repeated annealing.
