The invention relates to a preparation method for a magnesium oxide nanosheet. The method includes the steps of: putting magnesium powder into distilled water to conduct ultrasonic treatment so as to obtain a mixture; then putting the mixture into a reaction kettle to undergo reaction for 24-36h at 110-130DEG C; performing natural cooling under room temperature, and carrying out after-treatment to obtain the magnesium oxide nanosheet. The after-treatment steps include: centrifugal separation, washing by distilled water and drying at 60-80DEG C. The magnesium hydroxide formed by magnesium metal and water decomposes under high temperature and high pressure to generate the magnesium oxide nanosheet, which does not contain additive or surfactant, etc., and is easy to synthesize.
