Abstract

Kobalt oksida (Co₃O₄) nanopartikel merupakan bentuk oksida kobalt yang dapat digunakan sebagai sensor gas, anoda ion litium dari baterai, dan semikonduktor dalam degradasi zat warna. Tujuan dalam percobaan ini yaitu melakukan sintesis dan karakterisasi Co₃O₄ nanopartikel. Sintesis dilakukan menggunakan prekursor [Co(NO₃)₄.6H₂O] dan KOH sebagai pengendap dengan menggunakan perbandingan molar 1 : 1 melalui metode presipitasi. Dilakukan pula kalsinasi pada suhu 500^oC dan diperoleh padatan berwarna hitam akibat dekomposisi, yaitu terjadi perubahan dari Co(OH)₂menjadi Co₃O₄. Hasil sintesis Co₃O₄ dikarakterisasi menggunakan X-Ray Diffractometer (XRD). Dari hasil sintesis yang dilakukan, diperoleh Co₃O₄ nanopartikel berupa padatan hitam sebanyak 0,095 gram dengan rendemen sebesar 5,46%.
