Abstract
In this study, the titanium nitride (TiN) @manganese oxide (MnO) core-shell structured fibers were prepared by the coaxial electrospinning using tetrabutyl titanate and manganese acetylacetonate as raw materials, and polyvinylpyrrolidone (PVP) as the template. And then the fibers were annealed in ammonia to finally obtain the coaxial TiN@MnO fibers. XRD, FESEM, TEM, EDX and physical adsorption instrument were used to characterize the phase structure, morphology, composition and specific surface areas and pore sizes of the samples. It was demonstrated that the as-synthesized TiN@MnO fibers possessed coaxial structure with a surface area of 16 m2?g-1. As indicated from the cyclic voltammetry test, the capacitances of these fibers displayed 100 F?g-1（TiN 38F?g-1, MnO 66 F?g-1）at a scan rate of 20 mV?s-1 and 82 F?g-1 at a higher rate of 50 mV?s-1, which were resulted by efficiently combining the large capacitance of MnO with good electronic conductivity of TiN.
