The present invention provides a substance decomposing and removing agent that has the ability to effectively and sustainably decompose and remove a wide variety of substances. This substance decomposing and removing agent contains a crosslinked acrylate moisture absorbing/releasing agent and an air catalyst that comprises a metal composition containing iron, aluminum, potassium, and titanium. The proportional content of metals in the metal composition, relative to 100 ppm of iron, is 100-500 ppm of aluminum, 0.5-50 ppm of potassium, and 0.1-50 ppm of titanium. The use of the crosslinked acrylate moisture absorbing/releasing agent causes the concentration of water vapor around the air catalyst to be sustainably high, thus causing a large amount of OH radicals to be generated from the air catalyst and enabling the air catalyst to maximally exhibit said ability to decompose and remove substances. Moreover, the crosslinked acrylate moisture absorbing/releasing agent has the ability to adsorb substances. The substance decomposing and removing agent can be included in fibrous structures and various products in which a deodorizing or antibacterial ability is sought.本發明提供一種物質分解去除劑,其具有有效且持續地將廣大範圍種類的物質加以分解去除之能力。該物質分解去除劑含有:包含鐵、鋁、鉀、及鈦之金屬組成物構成之空氣觸媒、與交聯丙烯酸酯系吸放濕劑,就金屬組成物中的金屬含有比例而言,相對於100ppm的鐵,鋁為100~500ppm,鉀為0.5~50ppm,鈦為0.1~50ppm。藉由使用交聯丙烯酸酯系吸放濕劑,得持續提高在空氣觸媒周圍的水蒸氣濃度,藉此由空氣觸媒會產生大量的OH自由基,而能最大限度地發揮空氣觸媒的物質分解去除能力。更進一步,還賦予其交聯丙烯酸酯系吸放濕劑吸附物質之能力。此物質分解去除劑能被包含於尋求除臭性、抗菌性之纖維結構物與各種製品中。
