Description
Technical Field
The invention relates to the technical field of photoelectric catalytic materials, in particular to a palm SnS 2 which is self-assembled on flexible substrate carbon paper and exposes a high-activity surface and a preparation method thereof.
Background
With the accelerated development of economy and industry, global warming, energy shortage and environmental pollution problems continue to occur, and the tremendous consumption of traditional fossil fuels, such as coal and oil, has led to a dramatic increase in the concentration of carbon dioxide (CO 2) in the atmosphere and water pollution. In this situation, it is extremely important and urgent to develop various methods for converting carbon dioxide into carbonaceous fuels and for removing harmful pollutants. In contrast to biological and chemical methods, photocatalytic nanomaterials are sustainable green technologies that convert solar energy into environmental purification and produce renewable energy sources. Photocatalytic decomposition of CO 2 is of great interest as a means of converting CO 2 to hydrocarbons.
Tin oxide has great interest due to its wide application prospect in the fields of gas sensitivity, photoelectricity and the like. The mixed-valence tri-tin oxide has smaller energy band width and is expected to realize high photoelectric response under visible light. The applicant researches a preparation method of self-assembled stannous oxide nano-sheets on a flexible substrate in the earlier work, and the preparation method is simple, has good photoelectric response performance under visible light and has stable performance. However, the stannous oxide has almost no photo-thermal effect, and the photo-thermal catalysis is based on the synergistic effect between photochemical and thermochemical reaction paths, so that the catalytic activity can be obviously improved, and the catalytic reaction paths and the selectivity can be modulated. The development of a photo-thermal catalyst with wide absorption range, excellent photo-thermal conversion and high catalytic activity is important for solar energy utilization and catalytic reaction. Tin disulfide (SnS 2) has proper band gap (2.2 eV) and band edge position, and is a potential visible light photocatalyst. However, the SnS 2 still has the defects of no dominant morphology, low photoexcitation carrier separation efficiency, small specific surface area, poor catalytic dynamics and the like in the hydrothermal synthesis.

1) Taking SnCl 2·2H2 O powder and Na 3C6H5O7·2H2 O powder as raw materials, and carrying out hydrothermal reaction on the hydrophilically treated carbon paper to obtain the stannous oxide;
2) Drying the stannous oxide, vertically placing the dried stannous oxide into a reaction kettle containing thioacetamide solution, and performing hydrothermal vulcanization for 3-12 h at 160 ℃;
3) Cooling to room temperature, taking out the sample, washing the sample with deionized water, and then placing the sample in a 60 ℃ oven for drying, thus obtaining the product.
Preferably, the hydrophilically treated carbon paper is carbon paper treated by ultrasonic treatment with acetone, alcohol and deionized water, respectively.
Preferably, the hydrothermal reaction condition of the step 1) is that the reaction is carried out for 12 hours at 180 ℃.
Preferably, the thioacetamide solution has a concentration of 0.22mol/L.
The invention provides palm-shaped SnS 2 which is prepared by the preparation method and is self-assembled on flexible substrate carbon paper.
The beneficial effects of the invention are as follows: compared with the common hydrothermally synthesized tin disulfide, the prepared sample has a larger specific surface area and a large number of active centers, and forms a special palm tree-shaped alternative morphology of the nano-sheet structure; the palm tree-shaped SnS 2 has high-efficiency photo-thermal conversion efficiency, and compared with Sn 3O4, the palm tree-shaped SnS 2 has the advantages that the near infrared ray absorption is obviously improved, and the palm tree-shaped SnS 2 has better photo-catalytic performance.

Detailed Description
The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Example 1:
1) The synthesis of the stannous oxide is carried out according to the earlier work of the applicant, and comprises the following specific steps:
Cleaning a beaker and a measuring cylinder used in the experiment by using an ultrasonic cleaner; respectively ultrasonically cleaning the carbon paper by using acetone, alcohol and deionized water;
Weighing 1.073g of SnCl 2·2H2 O powder and 2.94g of Na 3C6H5O7·2H2 O powder, placing the raw materials into a mixed solution of 20mL of deionized water and 20mL of absolute ethyl alcohol, and placing the mixed solution on a magnetic stirrer to be stirred until the mixed solution is completely dissolved;
transferring the uniformly stirred reaction solution into a 50mL polytetrafluoroethylene reaction kettle, vertically placing the hydrophilized carbon paper into the reaction kettle, performing high-temperature reaction, performing high-temperature high-pressure reaction in an oven, and performing hydrothermal growth at 180 ℃ for 12 hours; cooling the reaction kettle to room temperature and taking out the sample;
Washing with deionized water, and drying in a drying oven at 60 ℃; obtaining the product.
2) Synthesis of tin disulfide
Weigh 0.667g Thioacetamide (TAA) into 40ml deionized water, sonicate:
Transferring the TAA solution into a 50mL polytetrafluoroethylene reaction kettle, vertically placing the dried sample into the reaction kettle, and carrying out hydrothermal vulcanization for 3 hours at 160 ℃; cooling the reaction kettle to room temperature and taking out the sample; washing with deionized water, and drying in a drying oven at 60 ℃; obtaining the product.
Example 2:
The procedure is as in example 1, except that the reaction conditions in step 2) are set to 160℃for 12h.
Example 3:
The procedure is as in example 1, except that the reaction conditions in step 2) are set to 150℃for 12h.
Figures 1 and 2 show XRD patterns of examples 1-3, from which it can be seen that at a temperature of 150 ℃ the material produced is a mixture of Sn 3O4 and SnS 2, and that pure SnS 2 is obtained at an elevated temperature of 160 ℃.
FIGS. 3 to 4 are XPS total diagram and tin valence diagram of the SnS 2 material prepared in examples 1 to 2, respectively. XPS of FIG. 3 shows complete disappearance of the peak position of O1S after vulcanization, appearance of S2 p and S2S indicates complete vulcanization of Sn 3O4, and FIG. 4 shows that the peak of Sn 3d after vulcanization changes from divalent and tetravalent coexistence to tetravalent tin alone also indicates complete vulcanization of Sn 3O4. I.e. example 1 and example 2 both produced pure SnS 2 material.
Fig. 5 is an SEM image of Sn 3O4, from which it can be seen that the nano-sheet structure having a large specific surface area is further increased after 3 hours of vulcanization as shown in fig. 6; continuing to vulcanize for 12 hours, it can be seen from fig. 7 that the double-layered nano-sheets with alternate sizes are formed, like a palm tree structure, which is more beneficial to enhancing light absorption and light thermal properties. Fig. 8 is a thermal imaging comparison chart of example 1 and example 2 irradiated for 180 seconds under visible light and near infrared light respectively, which shows that the tin disulfide prepared in the scheme has a photo-thermal effect, and the photo-thermal performance of the double-layer palm-shaped SnS 2 is better than that of the single-layer SnS 2.
Fig. 9 shows that the light absorption of the three-tin oxide and the single-layer and double-layer tin disulfide is significantly improved compared with that of the Sn 3O4 double-layer palm-like SnS 2.
Although embodiments of the present invention have been disclosed above, it is not limited to the details and embodiments shown and described, it is well suited to various fields of use for which the invention would be readily apparent to those skilled in the art, and accordingly, the invention is not limited to the specific details and illustrations shown and described herein, without departing from the general concepts defined in the claims and their equivalents.
