中文摘要:
由 TiO2 nanofibers 组成的膜成功地通过 tetra-n-butyl titanate 的简单 solvothermal water/n-hexane 接口反应被制作, NaOH 由酸的洗和锻烧的柱子处理列在后面。Tetra-n-butyl titanate 在接口与 NaOH 反应在 200 nm 和纵的尺寸下面与侧面的尺寸形成高质量的 nanofibers 几十测微计。膜被互相贯通形成并且灵活 nanofibers 重叠并且由有尺寸从的洞分布式几到几百纳米的十纳米。因为多孔的结构,这 nanofiber 膜在水里在染料的 photodecomposition 展出了高效率。
英文摘要:
A membrane consisting of TiO2 nanofibers was successfully fabricated through a simple solvothermal water/n-hexane interface reaction of tetra-n-butyl titanate with NaOH followed by post treatments of acid washing and calcination. Tetra-n-butyl titanate reacts with NaOH at the interface to form high-quality nanofibers with lateral dimensions below 200 nm and longitudinal dimensions of several tens of micrometers. The membrane is formed by the interpenetration and overlapping of the flexible nanofibers and distributed by holes with sizes ranging from several tens of nanometers to several hundreds of nanometers. Because of the porous structure, this nanofiber membrane exhibited a high efficiency in the photodecomposition of dyes in water.
