设计并制备了掺杂氮和硫的锐钛矿型TiO 2纳米晶，其中N和S原子分别位于晶体的体相和表层，取代晶格O。由于显著降低的电子电阻，N/S掺杂的TiO 2显示出比参比TiO 2纳米晶体优越的上级高速率锂存储能力，尽管前者具有较大的颗粒尺寸。
Anatase TiO2 nanocrystals doped with nitrogen and sulfur, where substitutional N and S atoms for lattice O, respectively, locate in the bulk and the surface layer of the crystals, were designed and prepared. As a result of remarkably lowered electronic resistance, the N/S doped TiO2 shows a superior high rate lithium storage capability to that of reference TiO2 nanocrystals, though the former has a larger particle size.
