Embodiment 1

[0026] At room temperature, prepare a 30 mM / L aqueous solution of copper nitrate for use as a stock solution, take 15 mL of copper nitrate aqueous solution and put it into a 100 ml flask, then add 15 mL of ultrapure water, heat to boiling, and place under magnetic stirring Quickly add 30mL 0.2 M / L nicotinic acid to keep boiling, and continue to react for 60 minutes. The color of the solution changes from light blue to blue, accompanied by solid precipitation. Centrifuge the resulting solution at 7000 rpm for 10 minutes , discard the supernatant, remove the unreacted reducing agent nicotinic acid, wash the obtained precipitate with boiling ultrapure water, centrifuge, discard the supernatant, repeat 3 times and dry to obtain octagonal Solid powder of copper nicotinic acid micron material.

Embodiment 2

[0028]At room temperature, prepare a 30 mM / L aqueous solution of copper nitrate for use as a stock solution, take 15 mL of copper nitrate aqueous solution and put it into a 100 ml flask, then add 15 mL of ultrapure water, heat to boiling, and place under magnetic stirring Quickly add 30mL 0.3 M / L nicotinic acid to keep boiling, and continue to react for 60 minutes. The color of the solution changes from light blue to blue, accompanied by solid precipitation. Centrifuge the resulting solution at 6000 rpm for 10 minutes , discard the supernatant, remove the unreacted reducing agent nicotinic acid, wash the obtained precipitate with boiling ultrapure water, centrifuge, discard the supernatant, repeat 3 times and dry to obtain the tetragonal nicotinic acid Solid powder of copper micron material.

Embodiment 3

[0030] Add 0.01 mL of 0.01 M p-nitrophenol solution, 2.5 mL of ultrapure water and 0.1 mL of 0.5 M sodium borohydride ice solution newly prepared into the quartz cuvette, the color of the solution changes from light yellow to bright yellow, According to the ultraviolet spectrum, the characteristic absorption peak of p-nitrophenol is at 400 nm. The mixed solution of copper nicotinic acid micron material with catalyst copper coins was added, and the sample was measured once every 30 s. According to the ultraviolet-visible light absorption spectrum, the absorption peak gradually decreased with the test time until it decreased to a straight line. The degradation rate It can reach more than 99%, and the corresponding solution color becomes colorless, and the characteristic absorption peak of p-aminophenol generated at the same time is at 300 nm.

Abstract

The invention provides a production method of copper-cone-shaped copper nicotinate micron materials. The copper nicotinate which is of a micron structure is produced by a one-step method, different shapes of micron structures can be obtained through control on the use of reactants, a quadrangle, a hexagon, an octagon and the like are formed along with different proportions of a reaction, the middle portion is hollow, the appearance is similar to a copper coin, and the particle parameter is within the range of 3 to 9 microns and the wall thickness is within the range of 1 to 5 micro nanometers through the representation of a scanning transmission electron microscopy. The copper-cone-shaped copper nicotinate micron materials can serve as a novel efficient recyclable catalyst so as to degrade the nitrophenol wastewater. The synthesis method is simple and easy to operate, the yield is high, the catalytic reaction is rapid, and the catalyst can be recycled.

Description

technical field [0001] The invention belongs to the technical field of micron catalysis, and in particular relates to a synthesis method of a functional copper coin-like copper nicotinic acid micron material and an application method thereof as a catalyst. Background technique [0002] In recent years, with the increasing development of modern industry, the discharge of pollutants is increasing rapidly, and the pollution problem is becoming more and more serious, which will cause harm to the health of animals, plants and human beings. Among them, p-nitrophenol, as an intermediate of some pesticides, medicines, dyes and degradation products of herbicides, can enter the human body through food, drinking water and skin and mucous membrane absorption, which directly affects human health. U.S. EPA (1980) included p-nitrophenol in the list of priority pollutants and limited its concentration in natural water bodies to below 10 ng / L [Complete Destruction of p-Nitrophenol in Aqueous...
