The electrolytic MnO2 particles with α∙γ-MnO2 is successfully prepared using one-step acid constant current electrodeposition method. Scanning electron microscope, N2 adsorption/desorption method and X-ray diffraction are employed for the material characterization. Scanning electron microscope result shows that the diameter of MnO2 particle is about 350–500 nm. A lot of mesoporous exist in the as-prepared...
