The invention discloses a method for preparing manganese oxide nano materials including: two valent manganese salt and alkaline salt as raw material, two manganese salts and alkaline salts were dissolved in ethylene glycol solvent, then the solution of the two kinds of dark red brown solution is mixed to form a uniform; the addition of water in the red brown solution and brown precipitate; mixing, separation, drying the precipitate water manganese stone ultrafine nanowire; water manganese stone prepared nanowires in air or nitrogen conditions, at 400 DEG -1050 DEG to obtain calcined manganese oxide nano material and manganese oxide nanoparticles. Because the water manganese stone obtained by this way for ultrafine nanowire structure, less than 10nm in diameter, about 1 mu m by manganese oxide nanowires obtained by calcination or particulate materials with uniform size, high specific surface area; the preparation method is simple, mild conditions, to reduce production costs, and convenient operation, high yield, low energy consumption. ?
