Hydrothermal Route

Uniform hematite (α-Fe2O3) hexagonal nanodisks with dominant (001) facets have been synthesized via hydrothermal route assisted with ethylene glycol (EG). XRD, SEM, TEM, HRTEM and SAED were employed to characterize the synthesized samples. The results show that the moderate addition of EG in the hydrothermal system creates an equilibrium condition for the crystal nucleation and growth, resulting in the uniform α-Fe2O3hexagonal nanodisks with dominant (001) facets. Due to the exposition of the special facets of (001) and (110), the α-Fe2O3nanodisks express superior catalytic activity for the decomposition of ammonium perchlorate (AP).

Structure And Microstructure

Cu2MnSnS4 (CMTS) is acknowledged as an alternative to traditional semiconductors. The structure and microstructure of synthetic CMTS depend on, among other things, the types of sulfur sources used. Traditionally obtained CMTS mostly has a tetragonal structure. In this study, the effect of using thiourea (Tu) or Na2S as a sulfur source on the product structure was compared using hydrothermal synthesis at 190 °C for 7 days (ethylene glycol with water in the presence of poly(vinylpyrollidone) was used as a solvent). When Tu was used, CMTS precipitated in the form of concentric microspheres, 1–1.5 µm in size, consisting of hexagonal (in the cores) and tetragonal (the rims) forms. Most probably, the rapidly formed hexagonal nucleus was later surrounded by a slower-forming rim with a tetragonal structure. In contrast, when Na2S was used as a precursor, microspheres were not formed and a fine crystalline material with a homogeneous tetragonal structure was obtained. This allowed for the choice of micromorphology and product structure during synthesis.

Regularities of formation of LaCoO3 oxide with a perovskite-type structure from precursors obtained by the citrate method and the original deposition method under conditions of mild hydrothermal synthesis using organic templates: ethylene glycol, D-glucose, D-galactose and D-fructose are considered. The proposed method of synthesis provides the necessary homogenization of cations in the resulting precursor compound and the homogeneous nature of the oxide compound. The absence at the final stage of the synthesis of reducing conditions makes it possible to further modify the formed perovskite with noble metals
