Controlling the morphology and size of alpha-MoO3 is crucial to obtain superior electrochemical properties for electrochemical energy storage and conversion devices. Herein, one, two and three-dimensional alpha-MoO3 have been controllably synthesized on a large scale with templates via a facile hydrothermal method, and the growth mechanism was investigated and discussed. These three alpha-MoO3 exhibit excellent pseudo-capacitive energy storage capability and long cycle life. The alpha-MoO3 nanorod not only has the best pseudocapacitance among as-prepared alpha-MoO3, but also demonstrates much higher capacitance than those of reported alpha-MoO3 nanostructures by 2-4 times. Our findings provide an effective solution for the controlled synthesis of different structures of alpha-MoO3, which can pave the way to further improve the energy storage and energy conversion efficiency of MoO3-based devices. This facile route could be potentially applied to rationally design other high performance oriented oxides.
