Nanometer manganese dioxide microspheres were prepared from sodium pyrosulfite acid and potassium permanganate via using W/O emulsions as template. SEM, TEM, XRD and FT-IR were used to characterize the MnO2 micropheres. The SEM and TEM images showed that the average diameter of the MnO2 micropheres was about 150nm. The XRD analysis indicated that the MnO2 micropheres was of non-crystalline and active. According to the experimental facts and characteristic of the products, the formation mechanism of the microsphere was discussed.
