摘要：

Mesoporous TiO2 was prepared via a sol-gel method from an ethylene glycol-based titanium-precursor in the presence of a non-ionic surfactant at pH2. Only the anatase structure was detected after annealing, while the BET specific surface area was measured as being 90 m(2)g(-1) with a rather monomodal pore diameter close to 5 nm. Electrochemical performances were investigated by cyclic voltarnmetry and galvanostatic techniques. Mesoporous TiO2 exhibits excellent rate capability (184 mAh g(-1) at C/5, 158 mAh g(-1) at 2C, 127 mAh g(-1) at 6C, and 95 mAh g(-1) at 30C) and good cycling stability. (C) 2007 Elsevier B.V.
