The present invention relates to the use of solids consisting of a metal-organic framework (MOF) and having the units of the following formula (I): MmOkXILp as a nitrogen-oxide catalyst. The present invention also relates to devices for enabling the implementation of said use. The nitrogen oxides in question are nitrogen monoxide and nitrogen dioxide, collectively referred to as NOx. The MOF solids of the present invention are advantageously capable of removing nitrogen oxides from a liquid or gaseous effluent, for example from water, from the exhaust gases of a vehicle, factory, workshop, laboratory, stored products, urban air vents, etc., without any reducing agent and at a low temperature. The DeNOx catalysis is a major issue for our societies. The invention can be used for reducing or even avoiding the consequences for public health of the toxic NOx gases resulting from human activity.
本发明涉及将由金属有机骨架(MOF)组成且具有以下式(I)的单元的固体用作氮氧化物催化剂。本发明还涉及用于实现所述用途的设备。所涉氮氧化物是一氧化氮和二氧化氮,统称为NOx。本发明的MOF固体有利地能够从液体或气态流出物中去除氮氧化物,例如从水中、从车辆、工厂、车间、实验室、储存产品、城市排气口等的废气中,无需还原剂且在低温下。脱氮催化是我们社会的一个重要问题。本发明可用于减少甚至避免由人类活动产生的有毒NOx气体对公共健康的影响。
