Abstract

Recently, three-dimensional graphene foams produced by CVD method have drawn significant attention due to their unique properties in many applications. In particular, their regularly interconnected structures provide a suitable platform for accommodating metal oxides, polymers etc. Therefore, these materials emerge as promising candidates for electrochemical applications. In this study, hydrothermal method of doping iron oxide nanoparticles on three-dimensional graphene foam was demonstrated for the first time. After doping the saturation magnetization value (Ms) of graphene foam was measured as 49,8 emu/g while the interconnected network structure of graphene foam was preserved. These results show that it is possible to use these materials for electrochemical applications.

Özet

Kimyasal buhar biriktirme yöntemi ile üretilen üç boyutlu grafen köpükler, eşsiz özelliklerinden dolayı, son yıllarda pek çok alanda giderek dikkat çekmeye başlamışlardır. Özellikle; metal oksit, polimer gibi malzemelerle kaplanmaya uygun olan düzenli ağ yapılarıyla elektrokimyasal uygulamalar için de aday malzemeler haline gelmişlerdir. Bu çalışmada, kimyasal buhar biriktirme yöntemi ile üretilen üç boyutlu grafen köpüklere ilk kez hidrotermal yöntem kullanılarak γ-Fe2O3 nanoparçacıkları katkılanmıştır. Katkılama işlemi sonucunda köpüklere ait doyum manyetizasyon değeri (Ms) 49,8 emu/g olarak ölçülmüş, grafen köpüğün ağ yapısının katkılama işlemi sonucunda da korunduğu görülmüştür. Elde edilen bu sonuçlar γ-Fe2O3 katkılı grafen köpüklerin elektrokimyasal uygulamalar için kullanılabileceği sonucunu ortaya çıkarmıştır.
