example 1

[0019] 1.822 g of cetyltrimethylammonium bromide was dissolved in 20 ml of deionized water, and stirred until completely dissolved to obtain an aqueous solution of cetyltrimethylammonium bromide. Add 1.128 g of stannous chloride dihydrate into the prepared cetyltrimethylammonium bromide aqueous solution, and stir for 5 minutes to completely dissolve it. Under stirring conditions, 20 ml of sodium hydroxide solution having a molar concentration of 0.75 mol / L was added dropwise to the above solution, and stirring was continued for 10 minutes after the addition was completed to obtain a reaction solution. The molar concentration of stannous chloride dihydrate in the reaction solution is 0.125mol / L, and the molar concentration of sodium hydroxide is 0.375mol / L; In the autoclave, after sealing, heat at 130°C for 15 hours. After the reaction, the reactor was cooled to room temperature with the furnace. After the resulting mixed solution containing the product was centrifuged at a s...

Abstract

The invention discloses a method for preparing a comby stannous oxide nanometer material. The method comprises the following steps of: putting stannous chloride dehydrate in a hexadecyl trimethyl ammonium bromide aqueous solution under the condition of stirring by adopting a hydro-thermal synthesis method to obtain a mixed solution; then, dropwise adding a sodium hydroxide aqueous solution to the mixed solution; stirring to obtain a final mixed solution, wherein in the final mixed solution, the molar concentration of the stannous chloride dehydrate is controlled to be between 0.10mol / L and 0.15mol / L, and the molar ratio of the stannous chloride dehydrate to hexadecyl trimethyl ammonium bromide to sodium hydroxide is 1:1:(2-4); putting the final mixed solution in a reaction kettle, wherein the degree of filling is 80-90 percent, and performing a hydrothermal reaction for 12-15h at the temperature of 120-160 DEG C; and performing centrifugation, washing and drying on the obtained product to prepare the comby stannous oxide nanometer material. The prepared comby stannous oxide nanometer material has an even porous structure and can be applied in the aspects of lithium ion battery anode materials, chemical synthesis catalysts and the like. The method disclosed by the invention has the characteristics that the operation is simple, the cost is low, the pollution is low and industrial large-scale production can be easily realized.
