Titania nanotube arrays (TNAs) were grown by anodic oxidation method, and molybdenum disulfide (MoS2) grafted TNAs have been synthesized via one-step hydrothermal process. The MoS2 grafted TNAs (MoS2/TNAs) when employed as an anode material in lithium ion battery, exhibited excellent areal specific capacity (similar to 430 mu Ah cm(-2)) at current density of 50 mu A cm(-2), which is 33% higher as compared to the pure anatase TNAs and 55% higher as compared to MoS2. Moreover, the capacity loss per cycle of MoS2/TNAs (similar to 0.21%) was significantly lower than anatase TNAs (similar to 1.47%), suggesting an increase of capacity retention.
