20.500.12556/DKUM-99961 Hidrotermalna sinteza in karakterizacija kovinsko-organskih poroznih materialov Hydrothermal synthesis and characterization of metal-organic frameworks Namen magistrskega dela je bil raziskati vpliv vrste kovinskega iona, sinteznih pogojev (temperature in časa) ter dodatka globoko evtektičnega topila (DES) na sintezo, strukturo in fizikalno-kemijske lastnosti kovinsko-organskih materialov (MOF). Materiale na osnovi železovih, bakrovih in magnezijevih ionov ter tereftalne kisline smo sintetizirali s hidrotermalno sintezo. V izbranih sintezah smo uporabili tudi DES na osnovi glikolne kisline (DESG) in uree (DESU). Pripravljene materiale smo karakterizirali z različnimi analiznimi metodami ter ovrednotili njihovo poroznost, kristaliničnost, površinske lastnosti in adsorpcijsko sposobnost z adsorpcijo dušika in metilen modrega. Rezultati so pokazali, da so lastnosti MOF pomembno odvisne od vrste kovinskega centra, sinteznih pogojev ter vrste in deleža DES. Najvišjo adsorpcijo dušika smo določili pri železovem vzorcu Fe-DESU50-110-20, in sicer 148,9 m²/g, medtem ko je med magnezijevimi vzorci izstopal Mg-DESU100-150-20 s 116 m²/g. Pri adsorpciji metilen modrega je bil najuspešnejši bakrov vzorec Cu-150-10 brez dodatka DES, ki je po 72 urah dosegel približno 100 % odstranitev barvila. Rezultati potrjujejo, da lahko z ustrezno izbiro kovinskega centra, sinteznih pogojev ter vrste in deleža DES pomembno vplivamo na lastnosti in adsorpcijsko učinkovitost sintetiziranih kovinsko-organskih materialov. The purpose of this master’s thesis was to investigate the influence of the type of metal ion, synthesis conditions (temperature and time), and the addition of a deep eutectic solvent (DES) on the synthesis, structure, and physicochemical properties of metal-organic frameworks (MOFs). We synthesized materials based on iron, copper, and magnesium ions and terephthalic acid using hydrothermal synthesis. In selected syntheses, we also used DES based on glycolic acid (DESG) and urea (DESU). We characterized the prepared materials using various analytical methods and evaluated their porosity, crystallinity, surface properties, and adsorption capacity through the adsorption of nitrogen and methylene blue. The results showed that the properties of MOFs depend significantly on the type of metal center, the synthesis conditions, and the type and proportion of DES. The highest nitrogen adsorption was observed in the iron sample Fe-DESU50-110-20, at 148.9 m²/g, while among the magnesium samples, Mg-DESU100-150-20 stood out with 116 m²/g. For the adsorption of methylene blue, the most successful sample was the copper sample Cu-150-10 without DES addition, which achieved approximately 100% dye removal after 72 hours. The results confirm that by appropriately selecting the metal center, synthesis conditions, and the type and proportion of DES, we can significantly influence the properties and adsorption efficiency of the synthesized metal-organic materials. kovinsko-organski materiali hidrotermalna sinteza globoko evtektično topilo procesni pogoji karakterizacija materialov adsorpcijske lastnosti metal-organic materials hydrothermal synthesis deep eutectic solvent process conditions material characterization adsorption properties true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2026-08-31 20:34:11 2026-09-23 13:34:07 2026-09-24 03:07:30 0000-00-00 00:00:00 2026 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 MAG_Zavrski_Patricija_2026.pdf MAG_Zavrski_Patricija_2026.pdf 1 CA381D6654D3DA6DF242DE5A442E0A19 aa25fa8f699529fb29d0d5417c74da68c51819635b752b11e9c7c33799ddbb72 43314168-b735-11f1-a2e0-00155d0001be https://dk.um.si/Dokument.php?lang=slv&id=213256 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
