Description
Technical Field
The invention belongs to the technical field of materials, and particularly relates to a ternary layered transition metal boride and a preparation method and application thereof.
Background
With the continuous growth of the global population and the increase of fossil fuel consumption, the development of renewable energy sources such as solar energy and wind energy becomes more and more important. H2The carbon-free fuel is a carbon-free fuel which stores energy in the form of chemical bonds, has the advantages of environmental protection, sustainability, good economy and the like, and has wide development prospect.The key of the hydrogen evolution technology is to improve the electrocatalyst activity of the catalyst and improve the reaction conversion efficiency by minimizing the overpotential required by the Hydrogen Evolution Reaction (HER). The catalysts studied at present mainly comprise transition metal sulfides, selenides, phosphides, carbides, nitrides, borides and the like.
The hydrogen evolution catalytic activity of two-dimensional transition metal borides has attracted a great deal of attention from scholars. Kim et al (chem. commun.,2019,55,9295) proposed that the synthesis of two-dimensional transition metal borides (MBene) can be performed by etching of MAB phase such as MoAlB. However, Alameda et Al found that MBene could not be etched directly from MoAlB due to the MoAlB phase having a jagged double Al layer. So far, despite attempts to etch MoAlB phases with a number of sets of issues, no successful preparation of two-dimensional MoB materials has been reported. Zhang and Bai et al (Acta Materialia,2017,132:69) consider Mo based on theoretical calculations2AlB2Is a precursor that is likely to etch MBene phase. Most current etching methods inevitably involve etching MoAlB (JACS,2019,141:10852) with hydrofluoric acid or in situ generated hydrofluoric acid, removing one layer of the double Al atomic layer with saw-tooth shape, resulting in Mo2AlB2. Hydrofluoric acid has strong corrosivity in the etching process, and the use and the post-treatment of the hydrofluoric acid have greater safety risks.
The invention adopts fluoboric acid to etch MoAlB, combines with tetraalkylammonium hydroxide treatment to prepare Mo2AlB2The material avoids the use of hydrofluoric acid or in-situ hydrofluoric acid in a MILD method in the experimental process, and improves the experimental safety; and Mo etched by fluoroboric acid method2AlB2Has higher electrocatalytic activity.

Detailed Description
The technical solution of the present invention will be described in detail by specific examples.
Example 1
1g of MoAlB powder was slowly added to a 40 wt% solution of the fluoroboric acid in a mass ratio of 60: 1. The mixture was then reacted at 80 ℃ for 48 h. And after the reaction is finished, completely cooling the product, centrifugally washing the precipitate by using deionized water until the pH value of the supernatant is more than 5, filtering, and drying the filter cake in a vacuum oven at 60 ℃ for 12 hours for later use, wherein the label is 80-H-MAB.
The product obtained above was added to a 25 wt% tetramethylammonium hydroxide solution (TMAOH) and reacted at 35 ℃ for 48 hours. Wherein the mass ratio of the tetramethylammonium hydroxide solution to the product is 20:1, magnetic stirring is used in the whole reaction process, and deionized water is used for centrifugal washing after the reaction is finished until the pH value is neutral. The product was dried in a vacuum oven at 60 ℃ for 12h and labeled 80-HT-MAB.
MoAlB and HBF4XRD spectra of intermediate etching product (80-H-MAB) obtained by reaction, TMAOH treated product (80-HT-MAB) and raw material MoAlB are shown in figure 1. The MoAlB raw material characteristic peak of the 80-H-MAB sample disappeared, and shifted from 2 θ of 12.61 ° to 13.61 ° based on the 020 diffraction peak corresponding to the intermediate layer, and the product contained AlF3(25.3 °) impurities, peaks at 13.6 °, 28.6 °, 38.6 °, 41.6 °, and 43.0 ° of 2 θ were assigned to Mo2AlB2The characteristic peak proves that one layer of the sawtooth-shaped double Al layer in the MoAlB is etched, and the MoAlB is successfully converted into Mo2AlB2. Derivatization of impurity fluorides of 80-HT-MAB samples after TMAOH treatmentThe peak was eliminated, demonstrating that the fluoride on the sample surface was successfully removed by treatment with TMAOH.
To investigate the HER electrocatalytic activity of the samples, 80-HT-MAB was tested using linear voltammetry (LSV) with a sample mass loading of 0.5mg cm-2. The test results are shown in FIG. 2, at a current density of 10mA cm-2The overpotential 241mV required by 80-HT-MAB indicates that it has good HER electrocatalytic activity.
Example 2
Same as example 1, but HBF4The aqueous solution treatment temperature was changed to 90 ℃ and the other steps were the same. And after the etching by the fluoboric acid, adding the obtained product into a tetramethylammonium hydroxide solution (TMAOH) with the concentration of 25 wt%, reacting for 48 hours at 35 ℃, magnetically stirring in the whole reaction process, and centrifugally washing with deionized water until the pH is neutral. The product was dried in a vacuum oven at 60 ℃ for 12 h.
As can be seen from an observation of fig. 3, the 020 diffraction peak of the fluoroboric acid etching product 90-H-MAB sample was shifted from 2 θ ═ 12.61 ° to 13.24 °, and the product initially contained MoF3(2 θ ═ 23.2 °) and AlF3(2 θ 25.3 °). After TMAOH treatment, the diffraction peak of impurity fluoride of the 90-HT-MAB sample disappears, and the XRD pattern accords with Mo2AlB2And (5) characterizing.
Comparative example 1
Same as example 1, but HBF4The aqueous solution treatment temperature was changed to 50 ℃ and the other steps were the same. And after the etching by the fluoboric acid, adding the obtained product into a tetramethylammonium hydroxide solution (TMAOH) with the concentration of 25 wt%, reacting for 48 hours at 35 ℃, magnetically stirring in the whole reaction process, and centrifugally washing with deionized water until the pH is neutral. The product was dried in a vacuum oven at 60 ℃ for 12 h.
As can be seen from FIG. 4, the 020 diffraction peaks of the sample 50-HT-MAB prepared by the fluoroboric acid etching product 50-H-MAB and TMAOH intercalation do not obviously shift, the intensity of the characteristic peak of the raw material is still strong, which indicates that Mo is not prepared2AlB2A material.
Comparative example 2
1.5gLiF is added to 30mL of 9mol L-1In the hydrochloric acid solution, after stirring for 10min by a magnetic stirring device, the MoAlB powder is slowly added into the mixed solution of the lithium fluoride and the hydrochloric acid, and then the reaction is carried out for 48h at 35 ℃. And after the reaction is finished, completely cooling the product, centrifugally washing the precipitate by using deionized water until the pH value of the supernatant is neutral, finally drying the product in a vacuum oven at 60 ℃ for 12 hours to obtain the product, and naming the product as 35-M-MAB, wherein M represents the reaction product and is prepared by etching by using a MILD method (HCl/LiF). The XRD pattern from the product (FIG. 5) corresponds to Mo2AlB2The characteristics of (1).
To study the HER electrocatalytic activity of the samples, they were tested using linear voltammetry (LSV) with a sample mass loading of 0.5mg cm-2. The test results are shown in FIG. 6 at a current density of 10mA cm-2The overpotential required for 35-M-MAB was 246mV higher than that for the sample 80-HT-MAB prepared in example 1. The overpotential (241mV) of 80-HT-MAB is 5mV lower than that of 35-M-MAB (246mV), which indicates that the sample prepared by the fluoboric acid etching method has higher HER electrocatalytic activity, and should be because the formed laminated structure is more obvious after the fluoboric acid etching and the TMAOH intercalation, and has larger contact area with the electrolyte.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
