本发明公开了种四氧化三锰/DWCNT纳米复合材料的制备方法及其应用，将高锰酸钾用水合肼还原为MnO纳米颗粒，以浓硝酸消化后的多壁纳米碳管（DWCNT）为载体，合成了MnO/DWCNT纳米颗粒，该纳米复合材料经电极转化后具有优异的超级电容性能。该纳米复合材料制作简单，成本低，比电容高，循环寿命长，具有极高的应用前景。 The invention discloses a preparation method and application of a Mn3O4/double walled carbon nanotube (DWCNT) nano-composite material. Mn3O4/DWCNT nanoparticle is synthesized by reducing potassium permanganate to Mn3O4 nanoparticles with hydrazine hydrate and taking a multi-wall carbon nanotube nitrified by concentrated nitric acid as a carrier, and the nano-composite material has excellent supercapacitor performance after being subjected to electrode conversion. The nano-composite material has the advantages of low cost, high specific capacitance, long cycle lifetime and extremely high application prospect, and is simple to prepare.
