In recent years, photocatalytic O 3 、H 2 O 2 And PMS has been studied extensively in water treatment, as opposed to O 2 Or H 2 The efficiency of O as a free radical generating source in the traditional photocatalysis technology for degrading pollutants in water is obviously improved. Is prepared from O 3 、H 2 O 2 And PMS introduces photocatalysis and oxidation VOCs for treatment, and has the potential of treating high-concentration VOCs. The key problem of the photocatalytic oxidation system is the development of high-performance catalyst.

Molybdenum disulfide (MoS) 2 ) Is a typical layered compound in which a molybdenum atom is sandwiched between two hexagonal close-packed S atoms by weak van der Waals' force, has a narrow band gap (1.9 eV), is good in chemical stability, large in specific surface area, strong in oxidation property, non-toxic, and it can also be used as TiO 2 Good cocatalyst of nano particles. And MoS 2 And TiO 2 2 In contrast, tiO 2 @MoS 2 Is one of the excellent photocatalysts.
However, the traditional catalysts in powder form have disadvantages in industrial applications: for example, they are easily blown away in air, are difficult to recover, and are harmful to the environment.

As one skilled in the art will appreciate, various names may be used to refer to a component. This specification and claims do not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. The description which follows is a preferred embodiment of the disclosure, but is made for the purpose of illustrating the general principles of the disclosure and not for the purpose of limiting the scope of the disclosure. The scope of the present disclosure is to be determined by the terms of the appended claims.
For the purpose of facilitating an understanding of the embodiments of the present disclosure, the following detailed description is to be construed in conjunction with the accompanying drawings, and the various drawings are not intended to limit the embodiments of the present disclosure.
In one embodiment, as shown in fig. 1, the present disclosure provides a method of preparing C-doped MoS 2 @TiO 2 A method of aerogel catalyst comprising the steps of:
s100: dissolving biomass natural polysaccharide or micromolecular polymer in deionized water, and adding MoS 2 Precursor and TiO 2 Stirring the precursor at room temperature to obtain a mixture;
s200: freezing and drying the mixture to obtain light gel;
s300: calcining the light gel to obtain C-doped MoS 2 @TiO 2 An aerogel catalyst.
In the embodiment, natural biomass polysaccharide or micromolecular polymer is selected as the material for preparing C-doped MoS 2 @TiO 2 Raw material of aerogel catalyst, which can be used as carbon source to TiO 2 Modified and can be used as a template for connecting ammonium thiomolybdate to construct a net structure, so that the finally prepared C-doped MoS 2 @TiO 2 The aerogel catalyst has larger specific surface area, and increases the exposable catalytic active sites.
The above process is further illustrated below with reference to specific examples.
Example 1:
1. dissolving 0.05g of carboxymethyl cellulose in 10ml of deionized water, then adding 0.26g of ammonium tetrathiomolybdate, stirring until the carboxymethyl cellulose is dissolved, then adding 0.5ml of isopropyl titanate, and stirring vigorously at room temperature for 24 hours to form a viscous mixture;
2. transferring the sticky mixture into a plastic mold, freezing for 5min by liquid nitrogen, and drying to obtain light gel;
3. placing the light gel in a high-temperature atmosphere furnace, heating to 150 ℃ at a speed of 5 ℃/min under the protection of nitrogen, preserving heat for 2h, heating to 900 ℃ at a speed of 2 ℃/min, preserving heat for 2h, and naturally cooling to room temperature to obtain the C-doped MoS 2 @TiO 2 An aerogel catalyst.
In this step, it should be noted that the light gel obtained by freeze drying is in the form of a lamellar structure aerogel under both macroscopic and microscopic conditions, the light gel is firstly calcined at a low temperature of 150 ℃ so as to be able to more completely retain the overall structure of the aerogel, and then slowly heated to 900 ℃ at a slow rate to carbonize the precursor. Aerogel structures are susceptible to collapse if the temperature is raised directly and rapidly to 900 ℃.
Example 2:
1. dissolving 0.2g of alginate in 10ml of deionized water, then adding 0.26g of ammonium tetrathiomolybdate, stirring until the ammonium tetrathiomolybdate is dissolved, then adding 1ml of tetrabutyl titanate, and violently stirring for 24 hours at room temperature to form a viscous mixture;
2. transferring the sticky mixture into a plastic mold, freezing for 10min by liquid nitrogen, and drying to obtain light gel;
3. putting the light gel in a high-temperature atmosphere furnace, and keeping the temperature in nitrogenUnder protection, firstly heating to 150 ℃ at the speed of 5 ℃/min, preserving heat for 2h, then heating to 900 ℃ at the speed of 2 ℃/min, preserving heat for 2h, and naturally cooling to room temperature to obtain C-doped MoS 2 @TiO 2 An aerogel catalyst.
Example 3:
1. dissolving 0.05g of polyacrylic acid in 10ml of deionized water, then adding a mixture of 0.26g of ammonium molybdate and thiourea, stirring until the mixture is dissolved, then adding 1ml of titanium tetrachloride, and vigorously stirring at room temperature for 24 hours to form a viscous mixture;
2. transferring the sticky mixture into a plastic mold, freezing for 20min by liquid nitrogen, and drying to obtain light gel;
3. placing the light gel in a high-temperature atmosphere furnace, heating to 150 ℃ at the speed of 5 ℃/min under the protection of nitrogen, preserving heat for 2h, heating to 900 ℃ at the speed of 2 ℃/min, preserving heat for 2h, and naturally cooling to room temperature to obtain C-doped MoS 2 @TiO 2 An aerogel catalyst.
Example 4:
1. dissolving 0.2g of polyethyleneimine in 10ml of deionized water, then adding a mixture of 0.26g of sodium molybdate and thioacetamide, stirring until the mixture is dissolved, then adding 1ml of titanium sulfate, and vigorously stirring at room temperature for 24 hours to form a viscous mixture;
2. transferring the sticky mixture into a plastic mold, freezing for 30min by liquid nitrogen, and drying to obtain light gel;
3. placing the light gel in a high-temperature atmosphere furnace, heating to 150 ℃ at the speed of 5 ℃/min under the protection of nitrogen, preserving heat for 2h, heating to 900 ℃ at the speed of 2 ℃/min, preserving heat for 2h, and naturally cooling to room temperature to obtain C-doped MoS 2 @TiO 2 An aerogel catalyst.
In the above examples, the mass of the biomass natural polysaccharide or the small molecule polymer is limited to the range of 0.05-0.2g, and it should be noted that if it is greater than 0.2g or less than 0.05g, the finally prepared catalyst is fragile, easy to collapse, and unable to form a gel structure, thereby increasing the difficulty of recovery.
FIG. 2 shows C-doped MoS 2 @TiO 2 XRD characterization pattern of aerogel catalyst, and its preparation methodComparing with the standard PDF card, it can be seen that, in FIG. 2, the diffraction peak is related to MoS 2 And TiO 2 The crystal structures correspond one to one, and TiO is found 2 The successful preparation of the catalyst was demonstrated for the standard rutile form.
C-doped MoS prepared from examples 1-4 above 2 @TiO 2 The aerogel catalyst, from the macroscopic morphology as shown in fig. 3, exhibits the morphological characteristics of an aerogel, being light and non-brittle. From the microscopic morphology as shown in fig. 4, it shows a stable layered structure connected with each other, and has a large specific surface area, increasing the exposable catalytic active sites, thus being able to overcome the problems of easy accumulation, easy blowing off and difficult recovery of the existing powder catalyst in the process of gas degradation of VOCs.
While the present disclosure has been described in detail with reference to specific embodiments, the above description of the embodiments is only for the purpose of facilitating understanding of the method and the core idea of the present disclosure, and those skilled in the art may change the embodiments and the application scope according to the idea of the present disclosure. Accordingly, the description should not be construed as limiting the disclosure.
