“…Several specific issues need to be addressed in future research aimed at expanding the applications and optimizing the performance of magadiites in the industrial context. A notable example is the development of a crystalline model for magadiite through a systematic study of the evolution of the crystallographic phase during and after the synthesis process. − This could facilitate achieving precise control of the morphology and surface chemistry of these materials, including both inorganic–inorganic and inorganic–organic hybrid magadiites, which is a complex task, since the properties are dependent on the structure. A priority in this field is to obtain modified magadiites with desirable surface morphology and functionalization.…”

The attractive properties of magadiite, a lamellar and crystalline material, could give rise to new industrial processes due to its unique and modulating intrinsic properties. In this context, the high degree of expansion of its lamellae, a key factor for its potential use in several areas of scientific research, has attracted the attention of several researchers. The aim of this review is to provide a historical overview of the hypothetical models developed to explain the magadiite crystalline structure. Furthermore, different synthesis strategies for the preparation of magadiites as sodic, protonic, and hybrid (inorganic−inorganic and inorganic−organic) materials are discussed along with several routes for obtaining modified magadiites. Also, the use of magadiite in catalytic reactions, notably in ethanol dehydration and fructose conversion reactions, is a growing area of research. Other potential applications include the adsorption and absorption of environmental pollutants (e.g., phenol and methylene blue in wastewater), use as a photocatalyst in the oxidation of toluene, and use in medicine (e.g., as a drug delivery or antibacterial/antifungal agent). This highlights the many opportunities for the development of new synthesis methods to obtain multifunctional materials in the search for new applications.

Synthesis, X-Ray Rietveld Analysis, Infrared and Moessbauer Spectroscopy of R 2FeSbO7 (R 3+ : Y, Dy, Gd, Bi) Pyrochlore Solid Solution. -Ln2FeSbO7 (Ln: Y, Dy, Gd) and Bi 2FeSbO7 are prepared by calcination of stoichiometric mixtures of Ln2O3 (Bi2O3), Fe2O3, and Sb2O3 in air (alumina crucible, 1100-1150 C, 24 h), the Bi variant by staged heating from 700 to 1000 C. The polycrystalline powders show particle sizes of 30-40 nm. Rietveld refinement of powder XRD data show that the compounds crystallize in the cubic space group Fd3m. The bands at 642 and 490 cm -1 observed in the FT-IR spectra of Y2FeSbO7 are ascribed to the stretching vibrations of the smallest inter-atomic bond M(Fe/Sb)-O in MO 6 octahedra and the Y-O' bond, respectively. Moessbauer spectra are discussed. -(JANA*, Y. M.; HALDER, P.; BISWAS, A. A.; ROYCHOWDHURY, A.; DAS, D.; DEY, S.; KUMAR, S.; J. Alloys Compd. 656 (2016) 226-236, http://dx.
