Impregnasi dan Karakterisasi Struktur Padatan Co3O4 pada Pendukung CaF2

Abstract

Pada penelitian ini dilakukan sintesis padatan berpendukung Co₃O₄/CaF₂ melalui metode impregnasi dengan variasi loading Co pada CaF₂ adalah 2,5; 5; 7,5; 10 dan 15% w/w. Padatan hasil sintesis dikarakterisasi strukturnya menggunakan difraktometer sinar-X (XRD). Struktur padatan CaF₂ adalah sistem kubik. Struktur kobalt oksida yang muncul pada difraktogram padatan berpendukung sesuai dengan PDF 01-1152 yaitu Co₃O₄ heksagonal. Seiring dengan meningkatnya loading Co₃O₄ pada CaF₂ maka intensitas puncak-puncak khas Co₃O₄ semakin tinggi misalnya pada 2q 36,87°, hal ini merupakan kebalikan dari intensitas CaF₂ yang semakin menurun seperti yang terlihat pada 2q 46,97°.
