Embodiment 1
[0035] A kind of nickel nitrate, tin protochloride, polyvinylpyrrolidone (PVP) and glycerol are raw materials to prepare Ni 3 sn 4 The steps of the base nanosphere structure composite material are as follows:
[0036] (1) Weigh 0.45 mmol of nickel nitrate, 0.45 mmol of stannous chloride, and 1 g of polyvinylpyrrolidone (PVP) respectively.
[0037] (2) Add the weighed reaction materials into a small beaker, add 8 mL of glycerin and 40 mL of isopropanol, and ultrasonicate for 60 min to disperse and dissolve each material in the mixed solvent to form a light green reaction clear liquid.
[0038] (3) Transfer the light green reaction liquid into a stainless steel reactor with Teflon lining, and react in a high-temperature oven at 180° C. for 6 h.
[0039] (4) After the reaction, the reactor was naturally cooled to room temperature, and the obtained light green powder was washed several times with absolute ethanol, and then dried overnight at 70°C.
[0040] (5) Under an argon at...
