Abstract

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
