Examples
Embodiment 1
[0020] Embodiment 1: Preparation of LiNH by liquid reaction method 2 BH 3
[0021] At room temperature 25°C, in an inert atmosphere, 0.308 g of BH 3 NH 3 Dissolve in 5 mL THF, add to 0.2295 g LiNH 2 , stirred vigorously at room temperature for 3 hours, and vacuum-dried the resulting mixed solution at 40° C. for 12 hours to obtain the final product. figure 1 is the XRD spectrum of the resulting product.
Embodiment 2
[0022] Embodiment 2: Preparation of LiNH by solid state reaction method 2 BH 3
[0023] At room temperature 25°C, 0.308 g of BH 3 NH 3 with 0.2295 g of LiNH 2 Mix and stir under an inert atmosphere, react for 1 minute, and vacuumize the product for 3 hours to remove impurity gas to obtain the product. figure 2 is the XRD spectrum of the resulting product.
Embodiment 3
[0024] Embodiment 3: Preparation of LiNH by liquid reaction method 2 BH 3
[0025] In an inert atmosphere at 10 °C, 0.308 g of BH 3 NH 3 Dissolve in 10 mL THF, add to 0.2295 g LiNH 2 , stirred vigorously at room temperature for 5 hours, and vacuum-dried the resulting mixed solution at 10° C. for 24 hours to obtain the final product.
