Demand for $MnO_{2}$ has been increased with interest for its various applications in the fields of battery, catalyst, and capacitor. In this study, $MnO_{2}$ hollow microspheres were synthesized by sacrificial core method. $MnO_{2}$ nano particles were produced by the hydrolysis and condensation of manganese acetate. The stable $MnO_{2}$ hollow microspheres can very well be synthesized with mixing 0.2% of water, 0.65 mM of manganese acetate, and 0.02 mM catalyst at a room temperature.
