preparation example Construction

[0027] A method for preparing nickel phosphate hollow nanospheres comprises the steps of contacting soluble dihydrogen phosphate and nickel salt in a solution system, reacting under hydrothermal reaction conditions, cooling, washing and drying to obtain nickel phosphate hollow nanospheres.

[0028] The inventor has determined through in-depth research that the best effect can be obtained when the molar ratio of soluble dihydrogen phosphate to nickel salt is in the range of 1:0.5~1:1.5. Although the final product nickel phosphate hollow nanospheres can be produced below or above this range, and the nickel phosphate nanospheres have a unique hollow structure and relatively large specific surface area. However, the molar ratio of soluble dihydrogen phosphate to nickel salt in the range of 1:0.5~1:1.5 is significantly better than the effect outside the above range, which is manifested in the larger area of ​​nanosheets and the more uniform structure of hollow nanospheres. . The m...

Embodiment 1

[0043] Mix 20 ml of 0.04 mol / L ammonium dihydrogen phosphate aqueous solution and 20 ml of 0.04 mol / L nickel acetate respectively, transfer to a 50 ml polytetrafluoro container and fix it in a stainless steel reaction kettle (polytetrafluoroethylene Containers, to avoid the use of metal ions in metal containers to participate in the reaction to cause pollution), and then directly heated in an oven at 180°C for 12 hours, and when the temperature of the reaction kettle was naturally lowered to room temperature, the obtained reactants were washed with water and ethanol in sequence for 3 The washed samples were dried in an oven at 60° C. for 10 hours to obtain nickel phosphate hollow nanospheres. figure 1 Transmission electron micrograph of the nickel phosphate hollow nanospheres prepared in Example 1. Depend on figure 1 It can be seen that the diameter of the hollow nanosphere is 200-400 nanometers. figure 2 It is the X-ray powder diffraction pattern of nickel phosphate hollow...

Embodiment 2

[0045] 20ml of 0.04 mol / L ammonium dihydrogen phosphate aqueous solution and 20ml of 0.02mol / L nickel acetate were mixed together, transferred to a 50 ml polytetrafluoro container and fixed in a stainless steel reaction kettle (polytetrafluoroethylene Containers, to avoid the use of metal ions in metal containers to participate in the reaction to cause pollution), and then directly heated in an oven at 180°C for 12 hours, and when the temperature of the reaction kettle was naturally lowered to room temperature, the obtained reactants were washed with water and ethanol in sequence for 3 Dry the washed sample in an oven at 60°C for 10 hours to obtain nickel phosphate hollow nanospheres with a diameter of 200-400 nm and a specific surface of 284 m 2 / g. The transmission electron micrograph and X-ray powder diffraction pattern of the nickel phosphate hollow nanospheres prepared in this example are similar to those in Example 1.

Description

technical field [0001] The invention relates to the technical field of inorganic functional nanometer materials, in particular to a nickel phosphate hollow nanosphere and a preparation method thereof. Background technique [0002] Phosphate has broad application prospects in the fields of light, electricity, magnetism and catalysis because of its rich framework elements, so the synthesis of phosphate has attracted much attention. In addition to the above properties, nickel phosphate can also be used as a pigment and electroplating material. However, compared with iron phosphate, the research and reports on nickel phosphate are relatively less. Hollow nanostructures have great advantages in electrode materials, pigments, adsorption and other application methods due to their large specific surface area. The current research on the hollow nanosphere material of nickel phosphate has not been reported yet. Contents of the invention [0003] The invention provides a method fo...
