Abstract
Istraživanja u području nanotehnologije u zadnjih nekoliko desetljeća su sve intenzivnija. Istražuje se sve od sinteze do primjene nanostruktura u raznim područjima ljudskog djelovanja. Cilj ovog rada je sintetizirati Ag/SiO2 nanokompozit primjenjujući dva različita reducirajuća agensa - natrijev borhidrid (NaBH4) i dopamin hidroklorid (DOPA). Karakterizacija dobivenog nanokompozita provedena je primjenjujući instrumentalne tehnike analize, kao što je dinamičko raspršenje svjetlosti (eng. Dynamic Light Scattering, DLS), UV-VIS spektrofotometrija (eng. UltraViolet-VISible) i FTIR spektroskopija (Infracrvena spektroskopija s Fourierovom transformacijom). Veličina dobivenih čestica nanokompozita s oba reducirajuća agensa je bila približno uniformna u rasponu od 2 do 10 nm, a nakon ispiranja i centrifugiranja taj se raspon drastično mijenja te dolazi do njihove aglomeracije, tj. do povećanja njihovih dimenzija.
Abstract (english)
Research in the field of nanotechnology has intensified in the last few decades. Everything from synthesis to the application of nanostructures in various fields of human activity is being explored. The aim of this work is to synthesize Ag/SiO2 nanocomposites. It was synthesized using two different reducing agents, sodium borohydride (NaBH4) and dopamine hydrochloride (DOPA). The characterization of the obtained nanocomposite was performed using instrumental analytical techniques, such as Dynamic Light Scattering (DLS), UV-VIS spectrophotometry (UltraViolet-VISible) and Fourier transform infrared spectroscopy (FTIR). The particle size of the nanocomposites with both reducing agents was approximately uniform in the range of 2 to 10 nm. After washing and centrifugation this range changes drastically and their agglomeration of the particles occurs, and their size dimensions increases.
