Abstract

Perovskit je rumen, rjav ali črn mineral s kemijsko formulo CaTiO3. Splošna formula perovskitne strukture je ABM3. Perovskiti so privlačne spojine za različne aplikacije, ker izkazujejo zanimive fizikalne in kemijske lastnosti, kot so elektronska prevodnost, električno aktivna struktura, gibljivost kisikovih ionov skozi kristalno mrežo, toplotna in kemijska stabilnost ter magnetne, multiferoične in termoelektrične lastnosti. Nekateri perovskitni materiali so zelo obetavni kandidati za izboljšanje učinkovitosti anodnih katalizatorjev, drugi so pokazali odlične absorpcijske lastnosti za fotovoltaične sončne celice, tretji se lahko uporabljajo za elektrokemijsko zaznavanje alkoholov, glukoze, plinov ... V zadnjem času so anorgansko-organski perovskitni materiali pritegnili veliko zanimanja zaradi njihove kemijske variabilnosti, strukturne raznolikosti in izjemnih fizikalnih lastnosti. Poudarek raziskav je zlasti na različnih metodah ugotavljanja lastnosti perovskitov in z njimi povezane uporabe.

Secondary title: Modern inorganic-organic perovskite materials
Secondary abstract: Perovskite is a yellow, brown, or black mineral with the chemical formula CaTiO3. The general perovskite structure formula is ABM3. Perovskites are attractive compounds for a variety of applications because they exhibit interesting physical and chemical properties such as electronic conductivity, electrically active structure, the oxide ions mobility through the crystal lattice, thermal and chemical stability, and magnetic, multiferroic and thermoelectric properties. Some perovskite materials are very promising candidates for improving the efficiency of anode catalysts, some have shown excellent absorption properties for photovoltaic solar cells, and others can be used for electrochemical sensing of alcohols, glucose, gases … Recently, inorganic-organic perovskite materials have attracted substantial interest due to their chemical variability, structural diversity, and outstanding physical properties. Current research is focused on different methods for determining the properties of perovskites and their related applications.
