摘要
如何实现对具有优异性能的高质量纳米结构单元及其组装体的可控宏量制备技术,一直是实现其在能源转换应用的瓶颈。在众多品种的纳米材料中,碲是一种重要的纳米能源材料。本报告将报道我们近年来发展的液相法宏量制备高质量碲纳米线的技术,讨论其稳定性及其优异的活性和反应性。以可大量制备的碲纳米线为反应物,运用化学转化法制备了一系列具有重要功能的无机纳米线及异质纳米线,而运用多重模板法又可进一步制备多种复合纳米线(管)和纳米电缆等。此外,我们还可实现多种纳米线组装体的宏量制备,包括有序纳米线薄膜、三维纳米线气凝胶和水凝胶。这些纳米线组装体可应用于光电转换器件、透明导电电极、智能变色、弹性导体、电催化等领域。
How to synthesize high quality nanoscale building blocks in macroscopic-scale and assemble them into macroscopic assemblies with diverse functions has been a bottleneck for their applications in energy conversion. In this talk, we report the scale-up synthesis of high quality tellurium(Te) nanowires, which is a kind of important materials for energy conversion and storage, then we discuss the stability of freshly prepared ultrathin Te nanowires, their enhanced reactivity and templating effects for scale up synthesis of a family of other functional one-dimensional(1D) nanomaterials including semiconductor, noble metal, carbon, polymer, and other composite nanowires by a multiplex templating process. In addition, a series of macroscopic assemblies of nanowires, including free-standing membranes, films, hydrogels, and aerogels can be fabricated, which exhibit enormous potential for attractive applications, such as electronic devices, transparent electrodes, elastomeric conductors, and electrocatalysis.
