| 英文摘要 | tio2/nitrogen-doped graphene nanocomposite was synthesized by a facile gas/liquid interface reaction. the structure and morphology of the sample were analyzed by x-ray diffraction analysis, x-ray photoelectron spectroscopy, scanning electron microscopy and transmission electron microscopy. the results indicate that nitrogen atoms were successfully doped into graphene sheets. the tio2 nanoparticles (8-13 nm in size) were homogenously anchored on the nitrogen-doped graphene sheets through gas/liquid interface reaction. the as-prepared tio2/nitrogen-doped graphene nanocomposite shows a better electrochemical performance than the tio2/graphene nanocomposite and the bare tio2 nanoparticles. tio2/nitrogen-doped graphene nanocomposite exhibits excellent cycling stability and shows high capacity of 136 mah g(-1) (at a current density of 1000 ma g(-1)) after 80 cycles. more importantly, a high reversible capacity of 109 mah g(-1) can still be obtained even at a super high current density of 5000 ma g(-1). the superior electrochemical performance is attributed to the good electronic conductivity introduced by the nitrogen-doped graphene sheets and the positive synergistic effect between nitrogen-doped graphene sheets and tio2 nanoparticles.
