Description

technical field [0001] The invention relates to a high-magnification honeycomb porous MnO2 composite nanofiber, which belongs to the technical field of chemical materials. Background technique [0002] Nanofibers refer to fibers with a diameter in the range of nanoscale (1-100nm), which can be divided into polymer nanofibers, inorganic nanofibers and organic / inorganic composite nanofibers according to their composition. Nanofibers have the characteristics of high porosity, large specific surface area, large aspect ratio, high surface energy and activity, and high fiber fineness and uniformity. At the same time, nanofibers also have some special properties of nanomaterials, such as quantum size effects and macroscopic properties. The special electrical, magnetic and optical properties brought about by the quantum tunneling effect. Nanofibers are mainly used in separation and filtration, biological and medical treatment, battery materials, polymer reinforcement, electronic an...
