Embodiment 1

[0024] First weigh 0.2 mmol of copper nitrate, 0.2 mmol of 1,3-di(4-pyridine) propane, 0.2 mmol of 5-tert-butylisophthalic acid and 0.4 mmol of sodium hydroxide solid in a beaker, and add 10 ml to it to remove Ionized water, stir for 10 minutes to disperse evenly. Transfer the above mixed solution to a polytetrafluoroethylene reactor and add an iron shell, tighten it and put it into a 120 oC React in the oven for 72 hours, then slowly cool down to 30°C over 12 hours o C promptly obtains the blue massive crystal product. After ultrasonic cleaning with deionized water at 60 o Dry at C to obtain [Cu 2 (bpp) 2 (tbip) 2 (H 2 O)]·2H 2 O photocatalyst.

Embodiment 2

[0026] First weigh 0.2 mmol of copper nitrate, 0.2 mmol of 1,3-bis(4-pyridine) propane, 0.2 mmol of 5-tert-butylisophthalic acid and 0.3 mmol of sodium hydroxide solid in a beaker, and add 10 ml to it to remove Ionized water, stir for 10 minutes to disperse evenly. Transfer the above mixed solution to a polytetrafluoroethylene reactor and add an iron shell, tighten it and put it into a 130 oC React in the oven for 72 hours, then slowly cool down to 30°C over 12 hours o C promptly obtains the blue massive crystal product. After ultrasonic cleaning with deionized water at 60 o Dry at C to obtain [Cu 2 (bpp) 2 (tbip) 2 (H 2 O)]·2H 2 O photocatalyst.

Embodiment 3

[0028] First weigh 0.2 mmol of copper nitrate, 0.2 mmol of 1,3-di(4-pyridine) propane, 0.2 mmol of 5-tert-butylisophthalic acid and 0.35 mmol of sodium hydroxide solid in a beaker, and add 10 ml to it to remove Ionized water, stir for 10 minutes to disperse evenly. Transfer the above mixed solution to a polytetrafluoroethylene reactor and add an iron shell, tighten it and put it in a 150 oC React in the oven for 72 hours, then slowly cool down to 30°C over 12 hours o C promptly obtains the blue massive crystal product. After ultrasonic cleaning with deionized water at 60 o Dry at C to obtain [Cu 2 (bpp) 2 (tbip) 2 (H 2 O)]·2H 2 O photocatalyst.

Abstract

The invention relates to a copper metal organic framework material with photocatalytic performance and a preparation method thereof, belonging to the field of preparation of environment-friendly photocatalytic materials. The material synthesis method used in the present invention is a hydrothermal method. The specific steps are as follows: first, uniformly disperse copper nitrate, 1,3-bis(4-pyridine) propane (bpp), 5-tert-butylisophthalic acid (H2tbip) and sodium hydroxide into deionized water, and then The mixed turbid liquid was transferred to a polytetrafluoroethylene reactor for hydrothermal reaction. The obtained product is washed and dried to obtain a blue blocky crystal, which is the photocatalytic material. The preparation process of the invention is simple, the obtained photocatalyst has high stability, has good degradation ability to organic dyes such as methyl orange, and has good application prospects in the fields of sewage treatment and the like.

Description

technical field [0001] The invention relates to a copper metal organic framework material with photocatalytic performance and a preparation method thereof, belonging to the field of preparation of environment-friendly photocatalytic materials. Background technique [0002] Metal-Organic Frameworks (MOFs) materials have a variety of topological structures, and have excellent performance and potential application value in the fields of fluorescence, sensing, gas storage and separation, so they have been widely used in the past two decades. It has attracted extensive attention from chemists and materials scientists. MOFs materials are composed of metal ions or metal ion clusters connected by organic ligands to form a structure that expands infinitely in three-dimensional space, so it has the advantages of both inorganic and organic materials. Inspired by the research on the photocatalytic properties of semiconductor materials such as TiO2, there have been more and more attempt...
