Abstract

Pengaruh konsentrasi larutan prekursor terhadap morfologi dan ukuran nanopartikel seng oksida (ZnO) yang disintesis menggunakan metode hidrotermal telah diteliti. Larutan ZnO dengan konsentrasi 15 mM, 20 mM, 25 mM, 30 mM dan 35 mM disiapkan menggunakan prekursor zinc nitrate tetrahydrate dan hexamethylenetetramine dengan pelarut aquades. Morfologi nanopartikel ZnO yang terbentuk dikarakterisasi menggunakan Scanning Electron Microscope (SEM) dan ukuran kristal dikarakterisasi menggunakan XRD. Hasil karakterisasi menggunakan SEM menujukkan bahwa sampel yang tebentuk mengalami aglomerasi. Hasil karakterisasi XRD menunjukkan bahwa sampel adalah ZnO dengan struktur heksagonal Ukuran kristal dihitung menggunakan persamaan Debye-Scherrer dan diperoleh bahwa ukuran kristal berada pada rentang 25,4 – 27,5 nm. Dari penelitian diperoleh bahwa variasi konsentrasi larutan prekursor menyebabkan adanya perubahan ukuran kristal tapi tidak terlalu signifikan.
