利用银纳米材料的反应活性,通过模板反应可以制备形貌和结构可控的多种金属纳米结构,然而,在模板反应过程中,银纳米模板剂通常被氧化成银离子作为副产物被遗弃.考虑到金属纳米结构具有的广泛应用前景,以银为模板剂大规模制备各种金属纳米结构过程中的成本和环境问题必须予以关注.为了解决这个问题,我们对此类模板反应过程中所产生的废弃副产物氯化银进行了回收,并以此为原料成功的制备出高质量的银纳米线.以模板反应制备金/铂纳米结构为例,银的平均回收率可达到69.8%~84.6%.此外,利用废弃副产物重新合成的银纳米线具有均一的尺寸分布,在模板反应和制备透明导电电极方面表现出优异的化学和物理性能.
With the reactivity of silver nanomaterials, a variety of metal nanostructures with controlled topography and structure can be prepared by the template reaction. However, during the template reaction, the silver nanometalate is usually oxidized to silver ions as byproducts. In view of the wide range of application prospects of metal nanostructures, the cost and environmental issues in the large-scale preparation of various metal nanostructures using silver as a template must be addressed.In order to solve this problem, Of waste byproduct of silver chloride was recovered, and as a raw material for the successful preparation of high-quality silver nanowires to template reaction preparation of gold / platinum nanostructures, the average recovery of silver can reach 69.8% ~ 84.6 %. In addition, silver nanowires synthesized by using waste by-products have uniform size distribution and exhibit excellent chemical and physical properties in template reaction and preparation of transparent conductive electrodes.
