Single crystalline TiO2-B nanoribbons with high-density nanocavities were successfully synthesized via a simple hydrothermal route. The as-prepared TiO2-B nanoribbons exhibited a large Brunauer, Emmett, and Teller (BET) surface area of about 305 m(2)/g because of the high-density nanocavities inside the thin nanoribbons. Electrochemical measurements indicated that the TiO2-B nanoribbons with dense nanocavities showed discharge specific capacity higher than those of TiO2-B nanotubes and nanowires. It was found that the dense nanocavities have an important influence on the electrochemical lithium intercalation properties.
通过简单的水热法成功合成了具有高密度纳米腔的单晶TiO₂-B纳米带。由于细纳米带内部的高密度纳米腔,所制备的TiO₂-B纳米带表现出约305 m²/g的大比表面积。电化学测量表明,具有致密纳米腔的TiO₂-B纳米带的放电比容量高于TiO₂-B纳米管和纳米线。发现致密的纳米腔对电化学锂嵌入性能有重要影响。
