Ferey, Chem-eur J, 2004, 10, 1373-1382. ) Aluminum nitrate (2.50g) and terephthalic acid (1.66g) were added to 65mL of N,N-dimethylformamide solvent, magnetically stirred at room temperature to completely dissolve, then the mixed solution was transferred to 100mL with The stainless steel reaction kettle lined with polytetrafluoroethylene is sealed and placed in an oven at 220 ° C. Under the action of self-generated pressure, it is heated and crystallized for three days. The oven was closed to obtain a white slurry product. The product was vacuum filtered, washed with N,N-dimethylformamide, and then vacuum-dried at 50° C. for 18 hours to obtain a white block product. The resulting product is ground and calcined. The calcination temperature is 280°C.

Abstract

The invention relates to a nanometer porous metal-organic framework compound composite material, in particular to a ferrocene-porous metal-organic framework compound composite material, and a preparation method and an application thereof. The mass ratio of ferrocene and porous metal-organic framework compound is 50-200 percent. The ferrocene-porous metal-organic framework compound composite material is prepared by the following steps: firstly, preparing the nanometer porous metal-organic framework compound; and secondly, loading the ferrocene on the porous material through a gaseous diffusion method. The invention adopts the nanometer porous metal-organic framework compound to fix the ferrocene of electronic media with electrochemical activity to be used as the electrode modification material so as to realize the detection of peroxide without enzyme. Because the nanometer material has large specific surface area, the invention improves the detection sensitivity and can be used for other electrochemical biological sensors based on the detection of peroxide.

Description

technical field [0001] The invention relates to a nanoporous metal organic framework compound material, in particular to a ferrocene-porous gold metal organic framework compound composite material which can be used as a sensitive material for hydrogen peroxide sensing and its preparation. Background technique [0002] Porous metal-organic framework compounds refer to crystalline polycrystalline materials with regular channel or hole structures that are jointly constructed by inorganic metal centers and organic functional groups connected to each other through covalent bonds or ionic bonds. As a new type of material, it shows attractive application prospects in the fields of gas adsorption, separation, catalysis, optics, electricity, magnetism, and chiral separation. However, there are few international reports on the application of porous metal-organic framework compounds or their composites in chemical sensors, and all of them are limited to discuss the potential of materia...
