中文摘要	In this paper, Zn2TiO4 and TiN nanoﬁbers were prepared by a facile combination of electrospinning followed by thermolysis under different atmospheres. An N,N-dimethyl formamide (DMF)–ethanol solution of poly(vinylpyrrolidone) (PVP), Ti(IV)–isopropoxide (Ti(OC4H9)4) and zinc acetate (ZnAc) was used as the electrospinning precursor and the electrospun nanoﬁbers were calcined at 600 C in air to generate Zn2TiO4 nanoﬁbers. Subsequently, a conversion from Zn2TiO4 nanoﬁbers to TiN nanoﬁbers was realized through a heat treatment at 1000 C under an ammonia atmosphere. Investigations using ﬁeld-emission scanning electron and transmission electron microscopes (FESEM and TEM) revealed the nano-scale ﬁbrous morphology of the obtained products. Energy-dispersive spectroscopy (EDS) and X-ray diffraction (XRD) studies conﬁrmed the chemical composition and crystalline structure of the Zn2TiO4 and TiN nanoﬁbers, respectively. The electrochemical properties of the as-prepared TiN nanoﬁbers indicated that the capacitance characteristic of the TiN phase was the electric double-layer capacitance. The value of the speciﬁc capacitance gradually decreased with the increase of discharge current density.
