Abstract

The polyol method has gained significant attention for synthesizing Silver nanowires (AgNWs), offering a straightforward, cost-effective, and versatile approach to producing high-quality nanowires. In polyol method, the choice of metal salts performs a crucial function in determining the properties of the final AgNW product. This research specifically explores the influence of different metal salts on the length and diameter of AgNWs synthesized through the polyol method. Each synthesis involved the use of two distinct types of salts, with NaCl being a constant component. Trace amounts of Iron(III) Nitrate (Fe(NO3)3), Copper(II) Chloride (CuCl2), and Potassium Bromide (KBr) were introduced in conjunction with NaCl. The morphology and dimensional distribution of the nanowires were analyzed using Field Emission Scanning Electron Microscopy, while X-ray Diffraction was applied to study the crystal structure of the nanoparticles. Notably, the utilization of KBr in the synthesis led to the production of AgNWs with the highest aspect ratio, resulting in nanowires measuring 6.2 ± 2.5 µm in length. Additionally, the synthesis assisted by CuCl2 revealed a substantial presence of other silver nanostructures, such as nanocubes and nanotriangles, alongside nanowires.

Poliol Sentezinde Metal Tuzlarının Gümüş Nanotel Morfolojisi Üzerindeki Etkisi

Abstract

Poliol yöntemi, yüksek kaliteli gümüş nanotellerin (AgNWs) sentezi için basit, ekonomik ve çok yönlü bir yaklaşım sunmasıyla dikkat çekmektedir. Bu yöntemde, kullanılan metal tuzları, elde edilen AgNWs ürününün özelliklerini belirlemede önemli bir rol oynar. Bu araştırma, poliol yöntemiyle sentezlenen AgNWs uzunluğu ve çapı üzerinde farklı metal tuzlarının etkisini incelenmiştir. Her sentezde Sodyum Klorür (NaCl) sabit bir bileşen olarak kullanılmış ve buna ek olarak iki farklı tuz türü eklenmiştir. NaCl ile birlikte eser miktarda Demir (III) Nitrat (Fe(NO3)3), Bakır(II) Klorür (CuCl2) ve Potasyum Bromür (KBr) kullanılmıştır. Nanotellerin şekli ve boyut dağılımı Alan Emisyonlu Taramalı Elektron Mikroskobu ile analiz edilmiş, nanopartiküllerin kristal yapısı ise X-ışını Kırınımı ile incelenmiştir. KBr tuzu kullanılarak yapılan sentezlerde en yüksek boy/en oranına sahip AgNWs üretildiği görülmüş ve bu nanotellerin uzunluğu 6,2 ± 2,5 µm olarak ölçülmüştür. Ayrıca, CuCl2 tuzu kullanılarak yapılan sentezde, nanotellerin yanı sıra nanoküpler ve nanoüçgenler gibi diğer gümüş nanoyapılarının da önemli ölçüde oluştuğu gözlemlenmiştir.
