Abstract

This report describes a facile preparation and electrochemical properties of Mn2O3 sub-micron powder via thermal decomposition of an isonicotinic acid manganese complex. An isonicotinic acid manganese complex of [Mn(INA)(2)(H2O)(4)](n), (INA=isonicotinic acid) was synthesized by liquid diffusion method using an aqueous solution of manganese acetate and isonicotinic acid as the raw material. Mn2O3 sub-micron powder was then prepared by solid-state thermolysis of the as-synthesized INA-Mn complex at higher temperature under atmospheric pressure. The obtained products were characterized by FTIR, TG-DTA, XRD, TEM and FESEM. As an electrode material for supercapacitors, the prepared Mn2O3 electrode shows a strong cycle stability in 0.5 mol.g(-1) Na2SO4 electrolyte and a specific capacitance of 88 F.g(-1) at a current density of 0.5 A.g(-1) vs. the saturated calomel electrode (SCE).
