今天給大家分享的是2014年11月份 《Applied Clay Science》上發(fā)表的一篇名為：Acid-treated vermiculites as effective catalysts of high-temperature N₂O decomposition

文章摘要如下：

Vermiculites treated with solutions of HNO₃, HCl and H₂SO₄ were tested in the role of catalysts for high-temperature decomposition of N₂O to N₂ and O₂. Acid treatment of clay mineral resulted in a partial leaching of components of its octahedral sheets, which were partially deposited on the surface of vermiculite. Such modification of the clay samples significantly increased their specific surface area and porosity as well as influenced their surface acidity. Acid treatment of vermiculites activated them in the process of high-temperature N₂O decomposition, however activation effect depended on type of acid used as well as duration of acid modification.
