Abstract

Abstrak

Sintesis nanopartikel Zinc Oxide (ZnO) dengan metode hidrothermal sangat dipengaruhi oleh beberapa parameter, salah satu diantaranya adalah perbandingan prekursor dan katalis dalam pelarut. Dalam penelitian ini telah berhasil disintesis nanopartikel zinc oxide dengan metode hidrothermal. Prekursor yang digunakan adalah zinc acetat dan katalis NaOH dalam pelarut ethanol. Perbandingan molaritas prekursor dan katalis adalah 0,008:0,5 dan 0,3:0,9. Karakteristik optik, morfologi dan struktur kristal nanopartikel ZnO masing-masing dilakukan dengan pengukuran UV-Vis, TEM dan XRD. Nanopartikel yang dihasilkan memiliki memiliki struktur kristal hexagonal wurtzite. Nanopartikel zinc oxide dengan perbandingan 0,3:0,9 memiliki karakteristik yang paling baik dibandingkan dengan nanopartikel dengan perbandingan 0,008:0,5. Reaksi dalam hidrothermal kaitannya dengan perubahan tekanan akibat peningkatan volume akan dikaji lebih jauh.

Abstract

Synthesis of Zinc Oxide (ZnO) nanoparticles by hydrothermal method is influenced by several parameters one of them is the ratio of the precursor and catalyst in a solvent. In this study, we have successfully synthesized of zinc oxide nanoparticles by hydrothermal method. The raw material of precursor is zinc acetate, NaOH as catalyst and ethanol as a solvent. The molarity ratio of precursor and catalyst are 0.008: 0.5 and 0.3: 0.9. The optical characteristics, morphology and crystal structure of ZnO nanoparticles were characterised by the UV-Vis, TEM and XRD, respectively. From XRD measurement, it was observed that samples have hexagonal wurtzite structure and all peaks are well fitted with JCPDS:36-1451 data. The growth condition in the ratio of 0.3: 0.9 showed the best sample with high quality crystal structure and rod form. The effect of molar ratio to the characteristics of nanoparticle will be studied further in relation with the change of volume, and pressure inside of the reactor.
