摘要

在保护气氛下，以铁粉和乙酸为原料，采用水离子交换法制备了铁交换沸石催化剂。这种原位生产铁（II）的简化策略被发现即使在小孔沸石的沸石框架内也能产生高度分散的铁，这对各种催化应用具有吸引力。将所得样品应用于NH3选择性催化还原NOx。

Novel and more facile synthesis of highly dispersed iron in small-pore zeolites by ion exchange for catalytic applications

Iron exchanged zeolite catalysts have been synthesized by an aqueous ion-exchange with iron powder and acetic acid under a protective atmosphere. This simplified strategy for producing Fe(II) in situ was found to lead to highly dispersed iron even within the zeolite framework for small-pore zeolites, which is attractive for various catalytic applications. The obtained samples were applied in the selective catalytic reduction of NO_x with NH₃.
