[0015] Example 1

[0016] 1.35 g (0.005mol) FeCl 3 ·6H 2 O and 3.60 g (0.0265mol) CH 3 COONa·3H 2 O is placed in a 1000mL three-necked bottle, 400mL of ethylene glycol is added, and the three-necked bottle is placed in 50 o Electric stirring in the C water bath for 2 hours to obtain a transparent yellow solution; transfer the above yellow solution to a 500mL Teflon stainless steel reactor, seal it, and place it at 200 o In oven C, the yellow solution in the reactor was reacted under autogenous pressure for 8 hours. After the reaction, the reactor was cooled with tap water to room temperature; the green precipitate obtained by centrifugal separation was washed three times with absolute ethanol, and then heated at 60 o Dry in oven C for 12 hours and store in a desiccator. The product is a three-dimensional pattern and hierarchical structure diethylene glycol ferrous alkoxide.

Abstract

The invention relates to a diethylene glycol ferrous alkoxide with a three-dimensional pattern multi-stage structure and a preparation method thereof, and belongs to the technical field of self-assembly of micro-nano multi-stage structure materials. The chemical formula of the diethylene glycol ferrous alkoxide with the three-dimensional pattern multi-stage structure is FeC4H8O3. The diethylene glycol ferrous alkoxide is of 7-8 mu m microspheres with the three-dimensional pattern multi-stage structure, formed by mutual center-to-center connection and self-assembly of petal-like nano-sheets which are 1.8-2.0 mu m wide and 80-100nm thick. The diethylene glycol ferrous alkoxide has the advantages that ferric chloride hexahydrate and sodium acetate trihydrate, which are cheap and easy to obtain are taken as raw materials, ethylene glycol is taken as a solvent, the low-concentration and mild dissolution conditions of two inorganic matters in the ethylene glycol mixed solution are controlled, no surfactant is added, and a solvent thermal method is adopted for getting the diethylene glycol ferrous alkoxide with the three-dimensional pattern multi-stage structure. The synthetic method has the characteristics of simplicity, convenience, economical efficiency, environmental friendliness and the like.

Description

technical field [0001] The invention belongs to the technical field of self-assembly of micro-nano multi-level structure materials, and in particular provides a three-dimensional pattern multi-level structure diethylene glycol ferrous alkoxide and a preparation method thereof. Background technique [0002] In recent years, the synthesis of three-dimensionally patterned iron alkoxides via self-assembly process has attracted increasing attention, mainly because the three-dimensional patterned iron oxides obtained by the pyrolysis of alkoxides have shown excellent properties in the fields of water treatment, drug delivery, and electrochemistry. and potential application prospects. Zhong et al reported a FeCl-based 3 ·6H 2 O, urea and surfactant tetrabutylammonium bromide are used as raw materials, and ethylene glycol (EG) is used as a solvent to synthesize a three-dimensional patterned iron alkoxide, which is used as a precursor to obtain a three-dimensional patterned iron ox...
