Mixed perovskites as multifunctional materials in pigment study
Provider: Grantová agentura ČR
Programme: Standardní projekty
Implementation period: 01.01.22 - 31.12.24
Workplace:
Fakulta chemicko-technologická - Katedra anorganické technologie
Investigator: Šulcová Petra
Description:
The project is devoted to preparation of multifunctional oxide perovskites with optimized composition and physical parameters tuned through advanced synthesis processes with purpose to improve their functional characteristics in the pigment field of studies that includes application as NIR-reflective ?cool? pigments and organic dye adsorbents. For the both applications, the most urgent issue concerns development of economically affordable and ecological compositions. To this purpose, new compounds on basis of ABO3 (A = Ca, Sr and B = Ti, Sn) will be developed. Modification with Mg, Al, Mn, Fe, Co and Ni will aim the formation of stoichiometric and non-stoichiometric perovskites with purpose to improve their optical and adsorptive activity. The next objective will be to relate the effect of experimental parameters and the synthesis approach to the physical properties of the powders and their performance in the focus application areas. Practical implications of the project may help to solve current problems of global dye pollution and slow down the extension of urban heat islands.
