Abstract
Istraţivanja u ovom radu usmjerena su na sintezu nanostrukturiranih ĉestica ZnO hidrotermalnom metodom te karakterizaciju istih. Kao izvor Zn 2+ iona korišten je cinkov(II)acetat dihidrat Zn(CH 3 COO) 2 ⋅ 2H 2 O, a kao otapalo apsolutni etanol uz dodatak NaOH. Za kontrolu rasta i oblika kristala korišten je sufraktant trietanolamin (TEA). Sinteze su provedene pri temperaturi T=55 ⁰ C u trajanju do 2 sata. Dobivene mlijeĉno bijele suspenzije su nakon termalne obrade centrifugirane, dekantirane i isprane ultraĉistom vodom, odnosno apsolutnim etanolom te je potom osušeni prah ZnO kalciniran na 400 ⁰ C. Pripravljeni uzorci su karakterizirani difrakcijom rendgenskih zraka na polikristalnim uzrocima (XRD), transmisijskom elektronskom mikroskopijom (TEM), pretraţnom elektronskom mikroskopijom (SEM/EDS), infracrvenom spektroskopijom s Fourierovom transformacijom (FT-IR) te je provedena i analiza distribucije veliĉine ĉestica. Prema rezultatima sintetizirani uzorci nanostrukturiranog ZnO štapićastog su oblika heksagonske vurcitne strukture.
Abstract (english)
Research in this work is focused on synthesis of nanostructured ZnO particles using the hydrothermal method and their characterization. Zinc acetate dihydrate, Zn(CH 3 COO) 2 ·2H 2 O was used as a source of Zn 2+ ions, and absolute ethanol with the addition of NaOH was used as a solvent. The surfactant triethanolamine (TEA) was used to control crystal growth and shape. The syntheses were carried out at a temperature T=55 ⁰ C in duration up to 2 hours. The resulting milky white solutions were centrifuged, decanted, and washed with ultrapure water or absolute ethanol and then obtained powder of ZnO was dried and calcined at 400 ⁰ C. The samples were characterized by using X-ray diffraction on polycrystalline powder (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM/EDS), Fourier transform infrared spectroscopy (FT-IR). In addition, analysis of particle size distribution was performed. According to the results, the synthesized nanostructured ZnO rod-shaped samples have a hexagonal wurtzite structure.
