Synthesis and electrochemical properties of α-MnO2 microspheres
چکیده انگلیسی

We report the synthesis of α-MnO2 microspheres by a low-temperature hydrothermal method involving no templates or catalysts. The products were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy-dispersive X-ray spectrum (EDX), transmission electron microscopy (TEM), Fourier transform infrared spectrum (FT-IR), and Brunauer–Emmett–Teller (BET). The results show that the as-synthesized products are mainly composed of large quantities of α-MnO2 microspheres having a sea-urchin shape and a few microspheres constructed of small nanorods. Electrochemical characterization indicates that the resulting α-MnO2 microspheres display promising discharge properties than the commercial electrolytic manganese dioxides (EMD) when used as cathodes in alkaline Zn-MnO2 batteries.
