摘要：

Hausmannite Mn3O4 polyhedral nanocrystals have been fabricated through a simple solution-based thermolysis process in the manganese acetate-alcohol system. Structural and morphological characterizations of the as-obtained product have been carried out using XRD, FTIR, Raman spectraoscopy, XPS, SEM and TEM. The formation mechanism of polyhedral nanocrystals was proposed. The cyclic voltammetry (CV) result show that the as prepared Mn3O4 electrode exhibits a good pseudo-capacitance behavior. A maximum specic capacitance of 173 F.g(-1) is obtained for the nanocrystals at a sweep rate of 5 mV.s(-1).
