Embodiment Construction

[0033] The technical solutions of the present invention will be further described below in conjunction with the drawings and embodiments.

[0034] In the present invention, MOF-808 refers to the metal-organic framework material MOF-808-F synthesized under certain temperature and solvent conditions with zirconium oxygen cluster as the secondary structural unit and trimesic acid as the ligand, and its molecular formula is Zr 6 o 4 (OH) 4 (F) 6 (btc) 2 , where F represents formic acid (formate). Fc@MOF-808-F means MOF-808-F is Zr 6 o 4 (OH) 4 (F) 6 (btc) 2 Composite material obtained by supporting ferrocene (Fc).

Abstract

The invention discloses a metal organic framework (MOF)-808 supported ferrocene composite material as well as a preparation method and application thereof. The composite material is prepared by loading ferrocene with Zr6O4(OH)4(F)6(btc)2, wherein F in the Zr6O4(OH)4(F)6(btc)2 is formic acid; in the composite material, a mass ratio of the Zr6O4(OH)4(F)6(btc)2 to the ferrocene is (20:1) to (5:1); and the composite material is used for adsorption of oxygen. According to the method provided by the invention, the ferrocene is introduced as a suitable oxygen adsorbing body, so that crystal collapsecaused by an oxide can be avoided while the adsorption performance of the oxygen is guaranteed.

Description

technical field [0001] The invention relates to a metal organic framework material, in particular to a composite material of MOF-808 loaded with ferrocene. Background technique [0002] As one of the most used chemical products in the world today, oxygen is widely used in energy conversion processes and other chemical production processes, with an annual output of more than 100 million tons. Pure oxygen has a wide range of uses: for example, portable breathing devices used in medical care and aerospace, as well as various energy-saving and emission-reduction technologies such as oxygen-enriched fuels that can reduce carbon dioxide emissions, natural gas conversion processes, and biomass gasification processes. On the other hand, the chemical nature of oxygen is very active, and its existence will lead to oxidation and corruption of food and medicinal materials, catalyst oxygen poisoning, and safety hazards in the production and transportation of certain flammable and explosi...
