Abstract

In this study, flower-like NiO structures were synthesized by hydrothermal method. Then, Fe3O4 was doped onNiO that NiO structures gain magnetic properties. TEM (Transmission Electron Microscopy) and SEM(Scanning Electron Microscopy) were used to assess the morphology of the NiO structures. XRD (X-rayDiffraction) was used to evaluate the crystal structures of the NiO structures. Magnetic properties of the NiOstructures were investigated using VSM (Vibrating Sample Magnetometry). Catalysis properties of the producedstructures were assessed use of products as catalyst in the reduction of 4-nitrophenol (4-NP) was examined.Especially NiO and Fe3O4 were found to exhibit excellent catalytic performance for nitrophenol reduction, whileNiO@Fe3O4 magnetic microflowers were found to exhibit very low catalytic activity.

Özet

Bu çalışmada, çiçek benzeri NiO hidrotermal yöntemle sentezlendi. Daha sonra NiO üzerine, Fe3O4 katkılanarak manyetik özellik kazandırıldı. Elde edilen ürünlerin kristal yapıları XRD (X-ışını kırınımı) metodu ile incelenmiştir. Üretilen yapıların morfolojik özellikleri SEM (Taramalı Elektron Mikroskopisi), ve TEM (Geçirimli Elektron Mikroskobisi ) ile karakterize edildi. Ayrıca manyetik ölçümleri için VSM (Manyetik Histeresis Ölçümü) analizi yapıldı. Daha sonra ürünlerin, 4-nitrofenolün (4-NP) indirgenmesinde katalizör olarak kullanımı incelendi. Özellikle NiO ve Fe3O4’ün nitrofenolün azaltılması için mükemmel katalitik performans sergilediğini görülürken NiO@Fe3O4 manyetik mikro yapıdaki çiçeklerin çok düşük katalitik aktivite sergilediğini belirlendi.
