Abstract

Mesoporous rutile TiO2 nanoneedles have been successfully synthesized using a reverse microemulsionmediated sol–gel method at room temperature. The materials were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and the Bruauner–Emmet–Teller (BET) adsorption method, and their electrochemical properties were investigated by galvanostatic charge and discharge tests. XRD observations revealed the formation of a pure rutile TiO2 phase. Furthermore, TEM observation revealed the presence of a highly porous needle-like morphology. The electrochemical measurements show that the nanoneedles deliver an initial capacity of 305 mA h g-1 as anode material for Li-ion batteries and sustain a capacity value of 128 mA h g-1 beyond 15 cycles. The reported synthesis is simple, mild, energy efficient, and without postcalcination
