20.500.12556/RUL-150262 Katalizatorji na osnovi materialov z visoko entropijo Catalysts based on high-entropy materials Materiali z visoko entropijo so nova vrsta materialov, ki so v zadnjem času postali zelo popularni in so se začeli aktivno raziskovati. Pri stabilizaciji faze ima velik doprinos entropija, ki je merilo razpršenosti energije in nereda. To diplomsko delo vsebuje klasifikacijo materialov z visoko entropijo in pregled nekaterih sinteznih metod omenjenih materialov. Delo se osredotoča predvsem na uporabo materialov z visoko entropijo kot katalizatorjev v različnih aplikacijah. Katalizatorji so danes nepogrešljivi v mnogih industrijskih procesih, saj znižujejo potrebno energijo, izpuste ter stroške obratovanja in povečujejo izkoristek procesov. Njihova težava je visoka cena, saj večinoma vsebujejo redke kovine. Glavni cilj odkritja novih katalizatorjev na osnovi materialov z visoko entropijo je znižanje cene z legiranjem s cenejšimi kovinami ali odkrivanje novih alternativ, ter izboljšava katalitske aktivnosti. High-entropy materials are a new type of material which recently gained in popularity and have started being actively researched. A major role in phase stabilisation is played by entropy which is a metric for the dispersion of energy and disorder. This work contains a classification of high-entropy materials and an overview of some synthesis methods of said materials. The work mainly focuses on the use of high-entropy materials as catalysts in different applications. Catalysts are nowadays vital in many industrial processes since they lower the required energy, emissions and costs of operation whilst increasing yield. Their problem is high price since they are mainly very rare metals. The main goal of discovering novel catalysts based on high-entropy materials is lowering the price either through alloying with cheaper metals or discovering entirely new alternatives while potentially improving catalytic activity. zlitine z visoko entropijo keramika z visoko entropijo katalizatorji high-entropy alloys high-entropy ceramics catalysts true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2023-09-15 10:30:00 2023-09-15 10:30:02 2023-11-16 10:18:49 0000-00-00 00:00:00 2023 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 22787 172382211 Suligoj_Brin_-_Katalizatorji_na_osnovi_materialov_z_visoko_entropijo.pdf Suligoj_Brin_-_Katalizatorji_na_osnovi_materialov_z_visoko_entropijo.pdf 1 5DE72E486E9A8AE592C55986B7B86126 93dd5efd2759277002a4b928827cb7207fb94630797fb1e382a5b5f4bb8e2a21 13b07604-53a2-11ee-9ef6-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=174828 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
