Problems solved by technology

However, the three-dimensional patterned iron alkoxides in the above reports are only used to prepare iron oxides with maintained morphology, and less attention has been paid to their structural nature and physicochemical properties; and the surfactants or organic materials used in their synthesis methods will It leads to high synthesis cost and environmental pollution during the treatment of reaction products, which is not conducive to large-scale production and application
However, using cheap and easy-to-obtain inorganic substances as raw materials and EG as a solvent, the preparation of three-dimensional patterned multi-level diethylene glycol ferrous alkoxide with antiferromagnetism has not been reported so far by a simple surfactant-free solvothermal method.

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...
