Abstract
Disclosed are a layered double oxide, a preparation method and use thereof. The preparation method of the layered double oxide includes: mixing magnesium oxide and a hydrate of a magnesium salt, and subjecting a resulting mixture to ball-milling to obtain a ball-milled material; mixing the ball-milled material and a hydrate of a manganese salt, and subjecting an obtained mixture to wet-milling to obtain a layered double oxide precursor; and subjecting the layered double oxide precursor to calcining to obtain the layered double oxide, where a molar ratio of magnesium in the magnesium oxide to magnesium in the magnesium salt is in a range of 1:1 to 6:1.
