Lithium storage performance in ordered mesoporous MoS2 electrode material

Highly ordered 2-D mesostructured MoS2 was prepared by a nanocasting approach using mesoporous silica SBA-15 as a hard template and phosphomolybdic acid (H3PMo12O40) as a precursor. The resulting material constructed by interconnected aligned and regularly packed nanowires shows a rod-shaped morphology (0.4–0.7 μm in diameter and 0.8–1.2 μm in length). This mesoporous MoS2 exhibits reversible lithium storage capacity as high as 630 mAh g−1 with excellent cycling performance when used as an electrode material for lithium ion batteries.
