Katijonų ir anijonų pakaitų įtakos Mg-Al sluoksniuotų dvigubų hidroksidų susidarymui ir savybėms tyrimas

Abstract

Layered double hydroxides have found various applications in many areas, such as catalysis, drug delivery, adsorption, separation, energy storage, hydrogen and oxygen evolution reactions, and corrosion protection. Majority of the commercially produced LDHs are made by co-precipitation, by hydrothermal synthesis or via the route that combines both these methods. These synthetic techniques make possible a production of well-crystalized product with good reproducibility; however, they are rather time-consuming. Therefore, the development of new synthetic approaches for LDHs is very important and timely task for materials scientists. The results presented in the current PhD thesis show considerable improvement not only in the synthesis procedure of LDHs, but in microstructural and physical properties of synthesized materials as well. Moreover, the search of novel LDHs chemical compositions by substituting magnesium and aluminium by other cations and introducing different anions offers a novelty and originality for the outgoing scientific investigations. Importantly, the obtained new LDHs showed specific properties, thus making its as suitable materials for different application
