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

The invention relates to a preparation method and application of a visible light response magnetic metal organic framework material; and the preparation method comprises the preparation steps of: firstly, preparing by adopting a solvothermal method to respectively obtain a polyamine metal organic framework material and nano Fe3O4; then introducing an epoxy group on the surface of the nano Fe3O4 byan ultrasonic assisted polymerization method to prepare epoxy functional nano Fe3O4; and then carrying out induction open-loop self-assembling on the epoxy functional nano Fe3O4 and the polyamine metal organic framework material by carboxylic acid to obtain the amino / carboxyl modified magnetic metal organic framework material. The product obtained by the method disclosed by the invention is in apowder form, is medium brown, and is uniform in particle size distribution and stable in property. The defect of solution agglomeration of a material material is overcome, and the prepared material isgood in dispersibility, high in magnetic performance, rapid in response, easy in obtaining of the raw materials and high in yield; and the visible light response magnetic metal organic framework material has visible light response, magnetic and accurate controllable topological structures, has a wide pH application range, achieves visible light catalysis and magnetism dual functions of the material and is beneficial to separation and recovery of a 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...
