Problems solved by technology

[0003] Among them, black phosphorus quantum dots, as a new type of quantum dot material that has just emerged in the past two years, are attracting more and more people's interest. Phosphorus quantum dots are very sensitive to air and water, and often require inert gas isolation protection, and the preparation process is relatively harsh, and only a single black phosphorus quantum dot in an organic solvent solution state can be obtained, which greatly limits the development of black phosphorus quantum dots. Functional application prospects

Embodiment 1

[0015] Disperse 0.35g of black phosphorus powder, 1.0g of attapulgite and 0.2g of NaOH in 100ml of n-methyl-2-pyrrolidone, and vigorously stir at 120°C for 10 hours under the protection of nitrogen. Take the upper suspension and dry it in vacuum to obtain the black phosphorus quantum dot / attapulgite nanocomposite material. The obtained product is observed with a scanning electron microscope and a transmission electron microscope. The SEM and TEM images are as follows: figure 1 with figure 2 Shown: the attapulgite rods present a nanorod-like structure, and the black phosphorus quantum dots are uniform in size and are evenly loaded on the attapulgite rods.

[0016] The black phosphorus quantum dot / attapulgite nanocomposite material in Example 1 is used for photocatalytic denitrification immediately after the preparation is completed. The gas ratio is: 0.1% (volume percentage relative to the total gas flow, the same below) NH 3 , 0.1% NO and 3% O 2 , N 2 As the balance gas, ...

Embodiment 2

[0030] Disperse 0.32g of black phosphorus powder, 0.8g of attapulgite and 0.3g of NaOH in 100ml of n-methyl-2-pyrrolidone and stir vigorously at 140°C for 8 hours under the protection of argon. After the reaction, centrifuge at 7000rpm for 2h , take the upper suspension and dry it in vacuum to obtain the black phosphorus quantum dot / attapulgite nanocomposite material, and the subsequent detection is as in Example 1.

Embodiment 3

[0032] Disperse 0.28g of black phosphorus powder, 1.0g of attapulgite and 0.3g of NaOH in 100ml of n-methyl-2-pyrrolidone, and vigorously stir at 160°C for 6 hours under nitrogen protection. After the reaction, centrifuge at 7000rpm for 2h, Take the upper suspension and dry it in vacuum to obtain the black phosphorus quantum dot / attapulgite nanocomposite material, and the subsequent detection is as in Example 1.

Abstract

The invention belongs to the field of new chemical materials, and particularly relates to a black phosphorus quantum dot / attapulgite nano composite material and a preparation method and application thereof. The preparation method includes: dispersing black phosphorus powder, attapulgite and NaOH in an organic solvent; enabling the solvent to be in thermal stirring reaction under inert gas protection; after the reaction is finished, taking upper-layer suspension liquid through high-speed centrifuging, and drying to obtain the black phosphorus quantum dot / attapulgite nano composite material. By using the nano composite material for denitrification, compared with conventional SCR denitrification, NO conversion efficiency at low temperature is improved obviously, so that energy consumption can be lowered greatly.

Description

technical field [0001] The invention belongs to the field of new chemical materials, in particular to a black phosphorus quantum dot / attapulgite nanocomposite material and its preparation method and application. Background technique [0002] As an important member of the family of nanomaterials, nano-quantum dot materials have attracted great attention due to their quantum tunneling effect, abundant active sites, up-conversion fluorescence, and excellent electron transport. and other fields have shown great application prospects. [0003] Among them, black phosphorus quantum dots, as a new type of quantum dot material that has just emerged in the past two years, are attracting more and more people's interest. Phosphorus quantum dots are very sensitive to air and water, and often require inert gas isolation protection, and the preparation process is relatively harsh, and only a single black phosphorus quantum dot in an organic solvent solution state can be obtained, which gr...
