A gas purification agent includes an electronegative film-forming agent and a foaming agent. The electronegative film-forming agent accounts for 20-80 wt % of the gas purification agent, while the foaming agent accounts for 20-80 wt % of the gas purification agent. The gas purification agent of such a composition can be used as a haze removing agent to effectively remove fine dust particles such as PM10 and PM2.5 from the air. The gas purification agent includes 2.5-25 wt % of the electronegative film-forming agent, 2.5-25 wt % of the foaming agent, and 50-95 wt % of a desulfurizing agent. The gas purification agent of such a composition can be used as a desulfurizing agent to remove sulfur-containing compounds from industrial exhaust gases. A method for using the gas purification agent is also provided.

Provided is a method for manufacturing a mesoporous inorganic oxide, which includes preparing a mixture of a metal salt selected from the group consisting of at least one kind of alkali metal-containing compound, at least one kind of alkaline earth metal-containing compound, and any combination thereof and an amorphous inorganic oxide; sintering the mixture of a metal salt and an amorphous inorganic oxide; and removing the metal salt contained in the sintered mixture, and a mesoporous inorganic oxide that is manufactured by the above method and is composed of an aggregate of inorganic oxide particles having a size of from 2 nm to 5 nm.
