Abstract

In this study, Ni-FeNi3-Fe3O4 metallic nanoalloys were successfully synthesized using the hydrothermal method at 180 °C for 2 hours. The structural and morphological properties of the synthesized metallic nanoalloys were characterized using X-ray diffraction (XRD), Fourier Transform Infrared Spectrophotometer (FTIR) and Scanning Electron Microscopy (SEM). When the diffraction patterns obtained from XRD analysis, it was determined that the high intensity peaks belonged to FeNi3 with cubic crystal structure and metallic Ni. It has been shown that the peaks obtained at lower intensity belong to the Fe3O4 structure. As a result of the FTIR analysis, the peaks obtained at 455.2 and 570.9 cm-1 were shown to be characteristic peaks of Fe-Ni and Fe-O bonds, respectively. SEM-EDS images showed that the synthesized metallic nanoalloys spherical particles with an average radius of 3.51 μm were the metallic Ni phase and the surfaces were covered with some FeNi3. It was determined that irregular shaped nanoparticles with an average radius of 63.33 nm were in FeNi3 structure together with Fe3O4.

Özet

Bu çalışmada, Ni-FeNi3-Fe3O4 metalik nanoalaşımlar hidrotermal yöntem kullanılarak 180 °C’de 2 saatte başarılı bir şekilde sentezlenmiştir. Sentezi gerçekleştirilen metalik nanoalaşımların yapısal ve morfolojik özellikleri X-ışını Kırınımı (XRD), Fourier Dönüşümlü Infrared Spektrofotometresi (FTIR) ve Taramalı Elektron Mikroskobu (SEM) kullanılarak karakterize edilmiştir. X-ışını Kırınım metodu sonucu elde edilen kırınım desenleri incelendiğinde yüksek şiddetli piklerin kübik kristal yapıdaki FeNi3 ve metalik Ni’e ait olduğu belirlenmiştir. Daha düşük şiddette elde edilen piklerin ise Fe3O4 yapısına ait olduğu gösterilmiştir. FTIR analizi sonucu 455,2 ve 570,9 cm-1’de elde edilen piklerin sırasıyla Fe-Ni ve Fe-O bağlarına ait karakteristik pik olduğu gösterilmiştir. SEM-EDS analizlerinden ise sentezlenen metalik nanoalaşımlar ortalama yarıçapı 3,51 μm olan küresel parçacıkların metalik Ni fazı olduğu ve yüzeylerin bir miktar FeNi3 nanoparçacıkları ile kaplandığı görülmüştür. Ortalama yarıçapı 63,33 nm olan düzensiz şekilli nanoparçacıkların ise Fe3O4 ile birlikte FeNi3 yapısında olduğu belirlenmiştir.
