AB  - In this paper, ultrathin (about 2.5 nm) manganite (MnOOH) nanowires were 
      synthesized by a simple wet chemical method at ambient temperature. 
      Temperature-dependent phase transition patterns of the prepared nanowires under 
      different atmospheres were systematically studied with thermogravimetric and 
      differential thermal analysis (TG/DTA). Based on the critical temperatures 
      demonstrated by the phase transition pattern, manganese oxides, such as Mn2O3 and 
      Mn3O4, have been obtained conveniently through calcination. Scanning electron 
      microscope (SEM), transmission electron microscope (TEM) and x-ray diffraction 
      results confirm that the annealed nanowires can both retain their original 1D 
      morphology and show good crystallinity. The electrocatalytic performance of the 
      as-prepared manganese oxides was also explored, which showed good response to the 
      reduction of H2O2 in alkaline media. Among the three manganese oxides, the MnOOH 
      nanowires exhibited the most prominent electrocatalytic efficiency and stability, 
      which provides a good candidate for modern industrial catalysis applications.
