Abstract One-dimensional uniform zinc antimonide (ZnSb) nanorods were successfully synthesized via a facile solvothermal method using ethylenediamine (en) as a “shape modifier” for the controlled synthesis of nanorods. These ZnSb nanorods show hexagonal phase and good crystallinity in nature. Also, they exhibited the average size of lengths and diameters for 1.4 µm × 170 nm. Based on the crystal structures and morphologies evolution of ZnSb nanorods, the formation mechanism of ZnSb nanorods has been proposed to be that the nanosized clusters nucleated first and then to the orientation growth depending on en molecular template, namely, a solvent coordinating molecular template mechanism. The electrochemical properties of the ZnSb nanorods are investigated as anodes for lithium-ion battery, which exhibit high reversible lithium storage capacity (478.5 mAh g−1 after 200 cycles) and superior electronic conductivity.

1 Introduction The research goal of nanomaterials is to synthesize nanosized materials with unique shapes and explore their practical applications in nanoelectronic devices, catalysis, biotechnology and others [1–3]. In recent years, much progress has been made in the preparation of one-dimensional (1D) nanomaterials such as wires, rods, and tubes, due to their size-dependent optical, nonlinear optical or optoelectronic functionalities [4–8]. Thus, it is a main challenge to develop a controlled-synthesis method to prepare 1D nanostructures for achieving specific morphologies and novel physicochemical properties. Zinc based or transition metal oxides nanomaterials are used as an electrode material for lithiumion battery, interdisciplinary products, to existence of wide bandgaps in photonic crystals has different applications such as optical switches, optical filters, wave guides and reflector. This behavior has opened important possibilities * Xinwei Wang [email protected] * Jilong Tang [email protected] 1

for the design of novel optical and optoelectronics [9–11]. Zinc antimonide (ZnSb) nanomaterials with narrow bandgap have been attracting more attention due to their nontoxic, low thermal conductivity, high electrical conductivity, and excellent thermal stability, which has been potentially applied to thermoelectric materials [12], electrodes for Liion batteries [13], phase change memory cells [14]. Specially, 1D nanostructure of ZnSb is worth to be studied due to their particular transport properties [
