A convenient hydrothermal processing followed by a postheat treatment route is proposed to synthesize well-dispersed,branched 
-MnO2 multipods from a branched 
-MnOOH precursor. The key steps in our approach are as follows: (1) by controlling thereactant concentration and reaction time, the monoclinic phase of MnOOH with novel branched multipod nanostructures is synthesized viathe hydrothermal reaction of MnSO4·H2O and NaClO3 at 160 
C for 200 min; (2) the prepared branched -MnOOH multipods are heatedunder an air atmosphere at 400 C for 2 h, and the branched -MnO2 nanostructures can be successfully obtained without changing theprecursor morphologies. The new structures presented here enrich the nanoscale community with new basic materials and offer a newapproach for increasing structural complexity and enabling greater potential applications. Furthermore, brief discussions about their formationmechanisms provide insight into the formation processing of other transition-metal oxide multipods.
