利用扫描和透射电子显微镜研究了在可见光区表现出高性能光催化剂的氧化锌纤维的形貌。ZnO纤维由ZnO微棒组成，每个微棒进一步由ZnO纳米晶体构成，其具有高结晶度、清洁表面和几十纳米的直径。纳米束衍射表明，ZnO纳米晶之间没有明确的取向关系。表面的微观结构被怀疑是强烈相关的可见光催化能力，这种纤维。
We have examined the morphology of zinc oxide (ZnO) fibers exhibiting high-performance of photocatalyst in visible-light region, by means of scanning and transmission electron microscopy. The ZnO fibers consist of ZnO micro-rods, and each of the micro-rods further is constructed from ZnO nano-crystals, which have high crystallinity, clean surfaces and diameters of a few tens of nanometers. From nano-beam diffraction, the ZnO nano-crystals are connected without definite orientation relations. The microstructure of surfaces is suspected to be strongly related to the visible-light photocatalytic ability of this fiber.
