Abstract
The invention discloses nano magnesium hydride and an in-situ preparation method thereof, including disposing and stirring magnesium chloride and lithium hydride in an organic solvent under a protection of an inert atmosphere, so as to obtain an organic suspension of a mixture; performing an ultrasonic treatment to the organic suspension, so as to promote a chemical reaction of the mixture. After the reaction is completed, the suspension is filtered; the solid reaction product is washed, centrifuged and dried to remove residual organic matter, so as to obtain nano-magnesium hydride.
Claims12
An in-situ preparation method of nano magnesium hydride, comprising steps of:
- step (1) disposing and stirring magnesium dichloride and lithium hydride in a first organic solvent under a protection of an inert atmosphere, so as to obtain an organic suspension of a mixture;
- step (2) performing an ultrasonic treatment to the organic suspension under the protection of the inert atmosphere, so as to promote a chemical reaction of the mixture, after the chemical reaction is completed, the organic suspension is filtered to obtain a solid reaction product;
- and
- step (3) washing, centrifuging and drying the solid reaction product by using a second organic solvent under the protection of the inert atmosphere, so as to remove a residual organic material and obtain nano-magnesium hydride.
