Microwave-Assisted Synthesis And Characterizatıon of Novel RuxM1-xAl2O3 Nanoparticles

Abstract

In this study, three metal composed of nanostructures of Ru_xM_1-xAl₂O₃ have been successfully synthesized by a simple and rapid microwave-assisted method using thiourea as the fuel and ethylene glycol (EG) as the reducing agent. In comparison with conventional heating, microwave-assisted method shortens the reaction time. The morphology, particle size and microstructure were analyzed using SEM and XRD. Microwave irradiation has yielded nanosized spherical phase particles. The mean grain size of the nanoparticles less than 100 nm. The FT-IR studies confirms the presence of metal–oxygen and metal-oxygen-metal bond. XRD and SEM of the synthesized nanoparticles show that the prepared nano compounds have low crystallinity and sphere and flower-like shape. Flower shape Ru_0.63Co_0.37Al₂O₃, Ru_0.93Ni_0.07Al₂O₃ and Ru_0.54Cu_0.46Al₂O₃ particles were obtained. Generally, the crystallite sizes were found in the range of 41-94 nm. The synthesized Ru_xM_1-xAl₂O₃ architectures (M: Fe, Co, Ni, Cu) were found to be polycrystalline and spherical in shape. The EDX analysis indicated that the elements of Ru, Fe, Co, Ni, Cu and Al existed in the products. The surface treatment of spray gold for elimination of charged effects were responsible for the signals of gold in the EDX analysis of the products. In other words, no impurities like N, S, P, Cl, etc. were detected except for Ru, Fe, Co, Ni, Cu and Al elements, indicating the nanoparticles were pure.

Öz

Bu çalışmada, yapısında üç metal bulunan nanoyapılar basit ve hızlı mikrodalga-yardımlı metod ile sentezlenmiştir. Bu sentezlerde tiyoüre yakıt olarak kullanılırken, etilen glikol (EG) yüzey gerilimini düşürücü ve indirgen olarak kullanılmıştır. Bilinen eski yöntemlerle kıyaslandığında bu yöntem reaksiyon süresini kısaltmıştır. Oksitlerin morfolojisi, parça büyüklüğü ve mikroyapısı SEM ve XRD ile analiz edilmiştir. Mikrodalga radyasyonu nanobüyüklükte küresel fazlı parçacıklar üretmiştir. Nanoparçacıkların ortalama tanecik boyutu 100 nm’den küçüktür. FT-IR çalışmaları metal-oksijen ve metal-oksijen-metal bağlarının varlığını doğrulamaktadır. Sentezlenen nanopartiküllerin XRD ve SEM sonuçları nano bileşiklerin düşük kristaliniteye sahip olduğunu, küresel ve çiçekbenzer şekillerde olduğunu göstermektedir. Çiçek tipi Ru0.63Co0.37Al2O3, Ru0.93Ni0.07Al2O3 ve Ru0.54Cu0.46Al2O3parçacıkları elde edilmiştir. Genelde, kristal büyüklükleri 41-94 nm aralığındadır. EDX analizleri sentezlenen bileşiklerin yapısında Ru, Fe, Co, Ni, Cu ve Al elementlerinin varlığını doğrulamaktadır. Bileşiklerin EDX analizlerinde gözlemlenen Altın elementine ait pik, yük etkisini yok etmek amacıyla yüzeye püskürtülen Altın’a aittir. Ek olarak, yapılarda N, S, P ve Cl gibi safsızlıkların olmayışı ve yalnız Ru, Fe, Co, Ni, Cu ve Al elementlerin gözlemlenmesi, nanoparçacıkların saf olduğunu göstermektedir
