Abstract

The invention relates to a preparation method of an iron molybdenum oxide (II) nanocube, and belongs to the preparation of an iron molybdenum oxide nanometer material with a regular shape. The method comprises the following steps: adding an iron source and a molybdenum source into a sealed pressure resistant reaction container according to the molar ratio of (1.5-3) to 1, using an ethanol and water mixing liquid as a solvent, respectively adding sodium acetate which accounts for 0.3-2.0% of the mass of the ethanol and water mixing liquid and polyvinylpyrrolidone to be used as auxiliary agents, uniformly stirring and mixing, and reacting for 8 to 40 hours at the temperature of 100 to 250 DEG C. The iron molybdenum oxide (II) nanocube is firstly prepared by the one-step liquid phase method; the used raw material is low in price, and easy to obtain; the preparation step is simple, and the operation controllability is high; the single crystal with uniformly distributed particle size and proper particle size is obtained, and the large-scale industrial production is facilitated. As the nanocube has the large specific area and regular surface shape structure, the nanocube is widely applied to the fields of new energy lithium iron cells and catalytic optics. The method is applied to the fields of optics, electrics, energy storage and catalyzing.
