采用可控静电纺丝和烧结的方法制备了平均直径为60、100和150 nm的锐钛矿型TiO2纳米纤维。烧结纤维是多晶的，由大小约为12 nm的密集堆积的TiO2颗粒组成。在高温下，金红石相在致密锐钛矿型TiO2纳米纤维的颗粒界面处成核
The anatase TiO2 nanofibers of average diameters 60, 100, and 150 nm were fabricated by controlled electrospinning of a polymeric solution and subsequent sintering of the as-spun fibers. The sintered fibers were polycrystalline and composed of densely packed TiO2 grains of size similar to 12 nm. The rutile phase nucleated at the particle interface of the dense anatase TiO2 nanofibers at a temperature of
