چکیده انگلیسی
Anatase TiO2 nanostructure coated and composited with N-doped carbon was simply fabricated by using acrylonitrile as carbon source. The carbon-coated composite with the TiO2 nanoparticles dispersed uniformly in the carbon matrix exhibits a high reversible capacity of 223.7 mAh gâ1 after cycling 100 times at 100 mA gâ1, excellent cycling stability and superior high rate performance (243.5, 219.0, 198.5, 175.8, 153.4 and 130.9 mAh gâ1 at 100, 200, 400, 800, 1600 and 3200 mA gâ1, respectively) when the carbonization temperature is around 550 °C. The synergistic effect of the combined coating and compositing the N-doped carbon is responsible for the outstanding electrochemical performance.
