Abstract
Organsko-anorganski hibridi su spojevi dobiveni kombinacijom anorganskih i organskih komponenti. Kako se sastoje od anorganskih i organskih dijelova mogu imati svojstva karakteristična za anorganske i organske spojeve. Sol-gel metoda je najrasprostranjenija metoda dobivanja takvih hibrida, no u ovom završnom radu istražit će se mehanokemijska metoda dobivanja organsko-anorganskih hibrida pomoću planetarnog kugličnog mlina. Cilj je bio sintetizirati 2D hibridni perovskit \( MA_{2}CuBr_{4}\) (MA = \( CH_{3}{NH_{3}}^{+}\)) koji je dopiran s \( Ni^{2+}\) u različitim masenim udjelima: a) 20% \( MA_{2}Cu_{0.8}Ni_{0.2}Br_{4}\), b) 30% \( MA_{2}Cu_{0.7}Ni_{0.3}Br_{4}\), c) 40% \( MA_{2}Cu_{0.6}Ni_{0.4}Br_{4}\) i d) 50% \( MA_{2}Cu_{0.5}Ni_{0.5}Br_{4}\). Za dobivanje hibrida korišteni su metil-amonijev bromid, niklov(II) bromid i bakrov(II) bromid. Sinteze su provedene na 900 rpm pri različitim vremenskim intervalima od 10, 20 i 30 minuta kako bi se istražili optimalni uvjeti za nastanak ciljanih spojeva. Dobiveni hibridi su analizirani pomoću infracrvene spektroskopije s Fourierovom transformacijom (FTIR) te termogravimetrijske analize (TGA).
Abstract (english)
Organic-inorganic hybrids are family of compounds made from the combination of inorganic and organic components. Since they are made from organic and inorganic parts, they possess properties from both sides. Sol-gel method is the most widespread method for synthesis of these hybrids, however, in this thesis a different method is used, called the mechanochemical method using a planetary ball mill. The goal was to synthesize 2D hybrid perovskite \( MA_{2}CuBr_{4}\) (MA = \( CH_{3}{NH_{3}}^{+}\)) doped with \( Ni^{2+}\) in different mass fractions: a) 20% \( MA_{2}Cu_{0.8}Ni_{0.2}Br_{4}\), b) 30% \( MA_{2}Cu_{0.7}Ni_{0.3}Br_{4}\), c) 40% \( MA_{2}Cu_{0.6}Ni_{0.4}Br_{4}\) and d) 50% \( MA_{2}Cu_{0.5}Ni_{0.5}Br_{4}\). Methylammonium bromide, nickel (II) bromide and copper (II) bromide were used in this synthesis. All the combinations were tried out at 900 rpm in three different time intervals of 10, 20 and 30 minutes to investigate optimal conditions for the formation of targeted compounds. These compounds were analyzed with Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA).
