Abstract:
Namen diplomske naloge je sintetizirati nanodelce maghemita iz piridinskega kompleksa Fe(C5H5N)4Cl2. Sinteza poteka v dveh stopnjah in sicer priprava piridinskega kompleksa, nato pa hidroliza in oksidacija te rumene soli do γ-železovega oksida ter naknadna dehidracija do maghemita. Uporabljene so različne tehnike hidrolize, oksidacije in dehidracije, ob spreminjanju fizikalnih pogojev. Postopno in sistematično želimo ugotoviti od katerih parametrov (katerih vmesnih stopenj) je odvisna uspešnost sinteze – kakšni so optimalni pogoji za nastanek nanodelcev maghemita in rast njegovih kristalov.

Title:
Maghemite (γ-Fe2O3) synthesis of pyridine complex Fe(C5H5N)4Cl2
Abstract:
The purpose of the thesis is to synthesize nanoparticles of maghemite from pyridine complex Fe (C5H5N) 4Cl2. The synthesis takes place in two stages, namely preparation of a pyridine complex, and then hydrolysis and oxidation of the yellow salt of γ-iron oxide, and subsequent dehydration to maghemite. We used a variety of techniques hydrolysis, oxidation and dehydration, when changing physical conditions. Gradually and systematically is to determine which of the parameters (which intermediate stages) depends on the success of synthesis - what are the optimal conditions for the formation of maghemite nanoparticles and the growth of its crystals.
