Abstract
Kako je u današnje vrijeme porasla potreba za novim materijalima s velikim izborom svojstava, istraživanje perovskita uvelike je poraslo. Zbog velike mogućnosti dopiranja ovih spojeva, perovskiti su se pokazali kao odlični kandidati za veliki broj novih tehnologija. U ovom diplomskom radu sintetizirani su nanokristalni oksidni perovskiti na bazi prijelaznih metala i lantanoida. Cilj uvođenja novih elemenata u sustav je povećati konfiguracijsku entropiju sustava kako bi se povećala njihova stabilnost te kako bi spojevi dobili nova svojstva. Svi navedeni perovskiti sintetizirani su modificiranom citratnom sol–gel metodom pri istim uvjetima, te su svi spojevi prošli jedan korak kalcinacije pri 600 °C u struji zraka s temperaturom zagrijavanja od 2 °C/min. Dobivani spojevi zatim su okarakterizirani rentgenskom difrakcijom na prahu (PXRD), termogravimetrijskom analizom (TGA/DSC), UV/VIS spektroskopijom i analizom specifične površine i eventualne poroznosti Brunauer–Emmett–Teller (BET) metodom.
Abstract (english)
As the need for new materials with a wide variety of properties has increased nowadays, perovskite research has grown greatly. Due to the high possibility of doping these compounds, perovskites have proven to be excellent candidates for a large number of new technologies. In this thesis, nanocrystalline oxide perovskites based on transition metals and lanthanides were synthesized. The goal of introducing new elements into the system is to increase the configurational entropy of the system in order to increase their stability and to give the compounds new properties. All the mentioned perovskites were synthesized by a modified citrate sol-gel method under the same conditions, and all compounds underwent one step of calcination at 600 °C in an air flow with a heating temperature of 2 °C/min. The obtained compounds were further characterized by the X-ray powder diffraction (PXRD), thermogravimetric analysis (TGA/DSC), UV/VIS spectroscopy, and Brunauer–Emmett–Teller (BET) analysis.
