We synthesize the surface modified mesoporous TiO2/G microspheres, which possess high surface area with 258 m2 g−1 and narrow pore size at about 7.8 nm.
The surface reaction mechanism of the UV-assisted synthesis mesoporous TiO2/G microspheres has been explored.
The as-made TiO2/G microspheres exhibit excellent electrochemical performances and deliver a capacity of 141 mAh g−1 upon 100 cycles even at 1 C.
