preparation example Construction

[0030] The preparation method of the uniform composite tin sulfide-nickel sulfide heterogeneous nanosheet array structure supported on the surface of the conductive substrate proposed by the present invention comprises the following steps and contents:

[0031] (1) In a beaker, first add tin tetrachloride, nickel chloride and thioacetamide, then add alcohol solvent, stir well to make it evenly mixed. Then add deionized water and continue to stir until it becomes a clear light green solution.

[0032] (2) Transfer the above solution to the reaction kettle, insert the pre-washed conductive substrate vertically, seal it and put it into the electric furnace, then heat it from room temperature to 140-180°C at a rate of 5-20°C / min, and keep it warm 4-12 hours. After naturally cooling to room temperature, open the reactor, take out the substrate, alternately rinse with deionized water and alcohol for 3-5 times, and dry at 50-80°C for 8-12 hours to obtain the , Uniform composite tin...

Embodiment 1

[0039] Example 1: In a 100mL beaker, add 0.631g of tin tetrachloride pentahydrate, 0.285g of nickel chloride hexahydrate and 0.451g of thioacetamide; then add 59mL of alcohol, stir well to make it evenly mixed; then add 1mL to Ionized water, continue to stir for 20 minutes until it becomes a clear light green solution.

[0040] Then the above solution was transferred to the reaction kettle, and a pre-washed carbon cloth (3.7×5cm 2 ) piece, sealed and placed in an electric furnace, then heated from room temperature to 160°C at a rate of 15°C / min, and kept for 8 hours. After naturally cooling to room temperature, open the reaction kettle, take out the carbon cloth, rinse it with deionized water and alcohol alternately for 5 times, and dry it at 60°C for 12 hours to obtain the carbon cloth-supported tin sulfide-nickel sulfide heterogeneous nanosheets array structure.

[0041] X-ray diffraction analysis shows that the black product is SnS loaded on the surface of carbon cloth 2...

Abstract

The invention relates to a uniformly-compounded tin sulfide-nickel sulfide heterogeneous nanosheet array structure loaded on the surface of a conductive substrate, and a preparation method thereof, and belongs to the technical field of new energy material preparation. The main body part of the product is a uniformly-compounded tin sulfide-nickel sulfide nanosheet, and vertically and closely growson the surface of a conductive substrate to form an array structure. The one-step solvothermal preparation method adopts nickel chloride, stannic chloride and thioacetamide as a nickel source, a tin source and a sulfur source respectively, a mixed solution of alcohol and water as a solvent and the conductive substrate as a skeleton, and effectively controls the growth rate of nickel sulfide by controlling the addition amount of water in order to achieve the synthesis of the product. The product obtained by the method has the advantages of high yield, high purity, controllable morphology and nopost-treatment; and the method has the advantages of simple devices and processes, strict and controllable synthesis growth conditions, high product yield, low cost, and clean and environmentally-friendly production process. Additionally, the product has an excellent electrochemical energy storage performance.

Description

technical field [0001] The invention relates to a uniform composite tin sulfide-nickel sulfide heterogeneous nanosheet array structure loaded on the surface of a conductive substrate and a preparation method thereof, belonging to the technical field of new energy material preparation. Background technique [0002] Tin sulfide (Sn x S y ) nanomaterials, as a member of layered two-dimensional transition metal semiconductor materials, have been widely studied in the fields of optics, electronics, photoelectrocatalysis, and gas sensing due to their abundant reserves and unique graphene-like structure. In recent years, tin sulfide has been used as electrode material for supercapacitors, lithium-ion (Li + ) and sodium ions (Na + ) There are more and more researches on batteries. Because tin sulfide nanomaterials have a unique two-dimensional layered structure, the interlayers are combined by weaker van der Waals forces, so they have a wider interlayer spacing (about 0.6nm), wh...
