A facile and energy-saving preparation of a-ZnMoO4 nanorods for enhanced Li-ion intercalation application

In this paper, one-dimensional alpha-ZnMoO4 nanorods with diameter of 30-50 nm have been prepared by a facile chemical precipitate reaction. This route is facile, energy-saving, no required special equipment and suitable for scalable synthesis. Transmission electron microscopy and fast Fourier transform pattern illustrate that the nanorods grow along the [011] crystal plane. When used as anode of lithium-half cell, the as-synthesized alpha-ZnMoO4 nanorods deliver a high capacity of about 417.6 mAh g(-1) after 800 cycles at the current density of 0.2 A g-1, an excellent rate (140 mAh g(-1) even at 2.0 A g(-1)) and fast lithium-ion diffusion coefficient (2.29 x 10(-17) cm(2) s(-1)), which is superior to that of the bulk counter and the previously reported. Such remarkable electrochemical performance is probably attributed to the favorable nanorods characteristic.
