Abstract

Ablacija iskrom postaje sve popularnija tehnika za sintezu ugljikovih nanostruktura zbog niza prednosti koje pruža, uključujući jednostavnost, ekonomičnost te visoku kontrolu procesa proizvodnje. Ova tehnika, koja se temelji na aerosolnoj ablaciji materijala u prisutnosti inertnog plina, omogućuje dobivanje raznovrsnih ugljikovih nanostruktura kontrolom parametara depozicije. U okviru ovog rada, provedena je sinteza dva uzorka ugljikovih nanostruktura, pri čemu je jedini promjenjivi parametar bio odabir vrste plina prisutnog tijekom procesa ablacije. Prvi uzorak sintetiziran je u atmosferi argona, dok je drugi uzorak sintetiziran u atmosferi dušika. Nakon sinteze, dobiveni uzorci detaljno su karakterizirani primjenom metoda analize površinskih svojstava kao što su AFM (eng. Atomic Force Microscopy), SEM (eng. Scanning Electron Microscopy) i BET (Brunauer-Emmett-Teller) analiza.

Abstract (english)

Spark ablation is becoming an increasingly popular technique for synthesis carbon nanostructures due to a range of advantages it offers, including simplicity, cost-effectiveness, and high control over the production process. This technique, based on aerosol ablation of materials in the presence of an inert gas, enables the production of diverse carbon nanostructures by controlling deposition parameters. In the context of this study, synthesis of two samples of carbon nanostructures was conducted, where the only variable parameter was selection of the gas type during the ablation process. The first sample was synthesized in an argon atmosphere, while the second sample was synthesized in a nitrogen atmosphere. After the synthesis, the obtained samples were thoroughly characterized using surface analysis methods such as AFM (Atomic Force Microscopy), SEM (Scanning Electron Microscopy), and BET (Brunauer-Emmett-Teller) analysis.
