脱氧剂Fe-MOF-74的制备及氧气吸附失活规律
Preparation and oxygen adsorption of deoxidation agent Fe-MOF-74 and its deactivation
摘要
Abstract
Open metal site metal organic frameworks (MOFs) Fe-MOF-74 can capture O2 from air or other oxygen-contain environment under low pressure, which can be applied to deoxidation in some special area. In this work, Fe-MOF-74 was successfully synthesized using two kinds of inert gas protection methods: flowing argon protection and no-flowing argon protection. The crystal from the first method was bigger than that from the second one, and the oxygen adsorption volume was higher too. Lower oxygen adsorption volume in no-flowing argon protection indicates few presence of Fe2+. The oxygen adsorption and desorption were tested for five times. No open metal sites exist because the oxygen cannot be removed from Fe-MOF-74 at all, and the material cannot chemisorption O2 anymore. The materials were exposed in the simulated air environments, which will be destroyed seriously in the water vapor atmosphere, it is therefore concluded that Fe-MOF-74 should not contact with water molecules.关键词
