Mangan Dioksit (MnO2) Katkılı Üç Boyutlu Köpüksü Yapıda Grafen Yapılarının Üretilmesi ve Karakterizasyonu

Günümüzde, üç boyutlu köpük benzeri grafen yapıları, benzersiz özellikleri nedeniyle yeni nesil malzemeler olarak büyük ilgi görmektedir. Özellikle bu malzemelerin iyi tanımlanmış birbirine bağlı yapıları nedeniyle bu malzemeler, özel uygulamalar için metal oksit, polimergibi başka malzemelerle kolaylıkla birleştirilebilinmektedir. Bu çalışmada MnO2 katkılı üç boyutlu köpük benzeri grafen yapıları. CVD yöntemi ve hidrotermal yöntem kullanılarak üretilmiştir. Raman ve XRD sonuçları MnO2 / grafen kompozitlerin morfolojisini göstermiştir. Ayrıca, SEM görüntüleri katkılanan MnO2 parçacıklarının iğne benzeri bir yapıya sahip olduğunu ve grafen iskeleti üzerinde kümelenerek ortaya çıktığını göstermiştir. Elde edilen bu sonuçlar, için MnO2 / grafen kompozitlerinin elektrokimyasal uygulamalar için elektrot olarak potansiyel kullanımının olduğunu göstermiştir
