“…At the same time, many orthoferrites have a set of functional properties that are important for application. These compounds include, in particular, bismuth orthoferrite [15][16][17][18][19]. There are publications [20][21][22][23] devoted to the study of solid solutions based on the Bi-doped YFeO 3 , but all these articles describe only the samples with an orthorhombic structure.…”

Nanopowders of Y 1−x Bi x FeO 3 (x = 0, 0.05, 0.10, 0.15) solid solutions were obtained by coprecipitation of hydroxides with simultaneous sonication and subsequent thermal treatment of the precipitate in air at 800 • C for 1 min. in the annealing-quenching mode. The results of X-ray phase analysis showed the formation of nanocrystalline solid solutions with a structure of hexagonal yttrium orthoferrite. The average crystallite size increases from 4 to 10 nm with the increasing bismuth content in the solid solution. The influence of Y 3+ substitution for Bi 3+ in yttrium orthoferrite on the photocatalytic activity of Y 1−x Bi x FeO 3 nanopowders during the Fenton-like degradation of methyl violet under the visible light irradiation has been studied. The maximum reaction rate constant of 0.0197 min −1 was shown by the YFeO 3 nanopowder, which has the smallest crystallite size of ∼4 nm.

“…One of the promising methods of synthesis of complex oxides is the method of glycine-nitrate combustion [50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65]. At the same time, this method not always guarantees the possibility of one-stage synthesis of complex oxide phases [22,28,32,33,46,58].…”

Nanocrystalline particles on the basis of La 2 (Ni,Mn,Fe) 2 O 6 variable composition phases of a double perovskite structure have been produced by glycine-nitrate combustion. The size of crystallites grows from 5 to 45 nm with an increase in iron content of synthesized particles. It is demonstrated that iron unevenly builds into octahedral sites of nickel and manganese ions substituting mainly manganese ions. At the same time, the dependence of double perovskite unit cell volume on the iron ions concentration is well described by Retgers' law. KEYWORDS double perovskite, nanocrystals, solution combustion, photovoltaics. ACKNOWLEDGEMENTS The authors express their gratitude to V. V. Gusarov for the attention he paid to the work. X-ray diffraction and SEM was performed using the equipment of the Engineering Center of Saint Petersburg State Institute of Technology. This study was financially supported by the Russian Science Foundation (project no. 20-63-47016). FOR CITATION Averkiev D.D., Larina L.L., Shevaleevskiy O.I., Almjasheva O.V.

“…A solution combustion method is advantageous for production of nanocrystalline ferrites with various compositions, including Bi 2 Fe 4 O 9 , at rather high temperature, since a fast combustion reaction process does not contribute to recrystallization particle growth [11][12][13][14][15][16][17][18][19][20][21][22].…”

“…Mössbauer measurements of the iron ion states in complex oxides, including nanocrystalline ones, provide useful information about formation mechanisms and magnetic behavior of complex oxides [1,7,12,13,[15][16][17][24][25][26][27]. Such experiments described in [1,7,17,27] have shown that the properties of Bi 2 Fe 4 O 9 -based nanomaterials may differ greatly from the bulk substance properties.…”
