文摘

Ultrathin TiO2 NSs-G is prepared by a hydrothermal and calcination treatment. TiO2 NSs-G 3D network provides more active sites due to larger surface area. The structural integrity facilitates electron transfer during cycling. The surface-to-surface intimate contact aid enhanced electrochemical performance.
