采用一种新的直接法制备了碳修饰的纳米TiO2。所制备的复合材料表现出互连的10 nm的TiO2纳米晶的形态与均匀的碳覆盖。作为锂离子电池负极，其具有184 mAh g− 1的高可逆容量和87.4%的初始库仑效率，优异的倍率性能和稳定的循环寿命，这归因于超细颗粒尺寸，均匀的碳涂层和高制备温度。
A novel direct preparation method was developed to prepare interconnected carbon-decorated TiO2nanocrystals. The as-prepared composite exhibited a morphology of interconnected 10 nm TiO2nanocrystals with uniform carbon coverage. As anode in lithium ion batteries, high reversible capacity of 184 mAh g− 1with 87.4% initial coulomb efficiency, outstanding rate performance and stable cycle life were observed, which was attributed to ultrafine particle size, uniform carbon coating and high preparation temperature.
