“…Although REE cations are included in the structure of LDHs mostly only partially and co-existed with another triply charged cation, several articles demonstrated the successful synthesis of binary RE-LDHs-Mg/Tb (Wang et al, 2017), Zn/Eu (Chen et al, 2018), Ca/Sc (Szabados et al, 2020), and Ni/La (Ensafi et al, 2016;Jiang et al, 2019). Our group is one of the first to synthesize Sc-containing LDHs (including the first binary Mg/Sc LDHs) (Vorontsova et al, 2007). Part of our studies is also dedicated to the synthesis and applications of Ce-containing LDHs (Golovin et al, 2020).…”

In this mini-review, we describe the currently available literature concerning synthesis and applications of layered double hydroxides (LDHs) containing rare earth cations (RE-LDHs), focusing on the catalytic activity of those compounds. The lack of studies of some rare earth elements (REE) and the insufficient knowledge of their catalytic activity in the structure of LDHs indicate the need for further research.

Magnesium-aluminum-iron layered hydroxides with hydrotalcite-like structure have been synthesized, and their chemical composition and crystal lattice parameters have been elucidated. Thermal decomposition of the iron-containing layered hydroxides has been studied by X-ray diffraction, thermogravimetry, and IR spectroscopy; the decomposition starts with loss of interlayer water, followed by dehydroxylation of metal hydroxide layers and decomposition of anions at higher temperature. Onset of the both decomposition stages has been shifted to lower temperature with increasing iron fraction in the sample. Magnesium-aluminum-iron hydroxides restore their structure after annealing and subsequent rehydration.
