| description | The invention discloses a method for preparing an alpha-MnO2 nanowire by adopting sulfamic acid for reducing potassium permanganate and an application. The method comprises the following steps: (1) adding sulfamic acid into deionized water, magnetically stirring, adding potassium permanganate and then magnetically stirring, thereby forming a purple black solution; and (2) pouring the solution intoa high pressure reactor lined with polytetrafluoroethylene and reacting for 10-20 hours at 160-180 DEG C; respectively washing the product with deionized water and absolute ethyl alcohol for 3 times;and drying for 8 hours at 60 DEG C, thereby acquiring the alpha-MnO2 nanowire. The alpha-MnO2 nanowire prepared according to the invention is in uniform size, is about 1-2 microns long and has a diameter about 25-35nm. The method disclosed by the invention is characterized by mild reaction condition, relatively low compounding temperature, short time, easiness in control and low production cost.The prepared alpha-MnO2 nan |
