采用温和、快速的室温溶液合成法合成了由粗糙表面的纳米平板组成的均匀的层次化BiOI纳米花。讨论了反应参数对形成三维花状纳米结构的影响。通过简单地改变体系中的反应参数，实现了纳米结构的形貌变化。研究了所制得的样品在可见光照射下对RhB染料的光催化性能，结果表明，花状BiOI分级纳米结构比球形BiOI纳米结构具有更大的比表面积、更高的光吸收和更好的光诱导电荷分离能力，因此具有更高的光催化活性。(C)2015爱思唯尔B.V.保留所有权利。
Uniform hierarchical BiOI nanoflowers composed of nanoplates with rough surfaces have been synthesized by a mild and rapid room-temperature solution synthesis approach. The effects of reaction parameters on the formation of 3D flower-like nanostructure were discussed. The morphology variations of the nanostructures were achieved by simply varying the reaction parameters in the system. The photocatalytic properties of the obtained samples for photodegradation of RhB dye under visible light irradiation were investigated, indicating that the flowerlike BiOI hierarchical nanostructure exhibits much higher photocatalytic activity than the sphere-like BiOI nanostructures owing to the larger surface areas, higher light absorption, and better photo-induced charge separation.
