Embodiment 1

[0057] Weigh Cu(Ac) 2 Dissolve 0.5g each of tetraethylenepentamine and tetraethylenepentamine in 10mL ethanol, and stir at room temperature for 10min to form a stable orange solution. The reaction solution was transferred to the reactor, and reacted at 180°C for 8h. After cooling, it was centrifuged, washed with deionized water and ethanol three times each, until the pH value was 7, and vacuum-dried at 60°C for 12 hours to obtain the polyamine metal-organic framework material.

[0058] Weigh 4g FeCl respectively 3 ·6H 2 O and 12g of anhydrous sodium acetate were dissolved in 100mL of ethylene glycol, stirred at room temperature for 10min, and stirred until a stable orange solution was formed. The reaction solution was transferred to a reaction kettle, and reacted at 180°C for 8h. After cooling, it was magnetically separated, washed with deionized water and ethanol three times each, until the pH value was 7, and vacuum-dried at 60°C for 12h to obtain nano-Fe 3 o 4 . Furth...

Abstract

A preparation method and application of a visible light responsive magnetic metal organic framework material, the preparation steps are: firstly prepare the polyamine metal organic framework material and nano-Fe by solvothermal method 3 o 4 , and then through the ultrasonic assisted polymerization method in the nano-Fe 3 o 4 Preparation of Epoxy-functionalized Nano-Fe by Introducing Epoxy Groups on the Surface 3 o 4 , and then self-assembled with carboxylic acid-induced ring-opening to obtain amino / carboxyl-modified magnetic metal-organic frameworks. The product obtained by the method of the invention is powdery, brown in color, uniform in particle size distribution and stable in property. Overcoming the shortcomings of magnetic material solution agglomeration, the resulting material has good dispersibility, high magnetic properties, fast response, easy access to raw materials, and high yield; it has both visible light response, magnetism, and precise controllable topological structure, and has a wide range of pH applications. The dual functions of visible light catalysis and magnetism of the material are realized, which is beneficial to the separation and recovery of the catalyst.

Description

technical field [0001] The present invention relates to a preparation method and application technology of a visible light responsive magnetic metal organic framework material, specifically a visible light responsive magnetic metal organic framework material and a preparation method thereof, and using the visible light responsive magnetic metal organic framework material of the present invention as a catalyst to degrade drugs and Personal care products, new environmental pollutants such as perfluorinated compounds, etc., to achieve environmental protection and other purposes. Background technique [0002] New pollutants refer to chemical pollutants that are "newly identified or previously unconfirmed", "not regulated by regulations", and "potentially or substantially threatening to human health and the ecological environment". New pollutants are usually detected recently due to the improvement of analytical detection technology or the discovery of new biological toxicity, an...
