“…Particularly, it should be mentioned that plenty of solution combustion methods have wide and promising prospects for industrial scale-up and allow varying multiple synthesis parameters, which simplify the process of obtaining nanopowders with controlled morphology and structure [47,48]. The authors of the current study have developed a two-stage method of thermal treatment of X-ray amorphous combustion products based on the synthesis of a completely X-ray amorphous powder under conditions of glycine-nitrate combustion with a significant lack of organic fuel (glycine) and its subsequent heat treatment at temperatures of 500-800 • C. This specific method has been successfully applied to the synthesis of several systems of rare earth orthoferrites [49,50] and multicomponent spinel-type ferrites [51,52]. In addition, the solution combustion method is low-cost, offers a high performance, and is affordable even for small-scale production.…”

The active development of water purification functional materials based on multicomponent spinel ferrites makes it necessary to search for new efficient methods of obtaining initial nanostructured powders. In this study, a two-stage method for the synthesis of perspective pollutant absorption agents based on NixZn1−xFe2O4 (x = 0, 0.3, 0.7, 1.0) spinel ferrites are proposed and implemented. The approach is based on the synthesis of the initial powder using the solution combustion method and its subsequent thermal treatment in the air. It was found that synthesized samples are single-phase Ni-Zn ferrites with an average crystallite size of 41.4 to 35.7 nm and a degree of crystallinity of ~95–96%. The analysis of antimicrobial activity against four diverse test-cultures: Escherichia coli ATCC 11229 (non-spore-forming gram-negative), Bacillus cereus ATCC 10702 (spore-forming gram-positive), Staphylococcus citreus NCTC 9379 (non-spore-forming gram-positive), and Candida tropicalis ATCC 750 (yeast) showed that almost all of the synthesized powders exhibit an advanced ability to inhibit the growth of the microorganisms mentioned above. The compositions obtained can be a perspective basis for both natural and wastewater purificators with magnetic separation ability and can find biotechnological and biomedical applications as promising antimicrobial materials.

“…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.

“…Often, within the framework of the classical single-phase method of solution combustion, even due to the selection of various types of organic fuels, it is difficult to obtain particles with a size less than 15-20 nm and a specific surface area of more than 40-50 m 2 /g. To solve this problem, the authors of this work proposed a two-stage synthesis technique based on thermal treatment of X-ray amorphous combustion products, which consists in the synthesis of the initial powder with a significant lack of fuel and further mild heat treatment at 500-700 • C. This technique has been repeatedly and successfully used to synthesize many systems of REE orthoferrites and spinel ferrites and has shown its high efficiency, including for the production of thermocatalytic and photocatalytic materials [32][33][34].…”

Nickel ferrite nanopowders were obtained under conditions of solution combustion with the addition of various types of organic fuels (glycine, ascorbic acid, oxalic acid, and malic acid) and studied as photocatalysts in the photodegradation of methylene blue. Photocatalytic measurements were carried out under the action of visible light in model dye solutions. The highest photocatalytic activity was found in the case of a sample synthesized using malic acid as a fuel and in which the largest specific surface area (128.1 m 2 /g) and the smallest particle size (18 nm) were observed. The obtained dependences of the photocatalytic activity of the synthesized samples demonstrate its strong dependence on morphological and structural parameters. Thus, with an increase in the particle size and a decrease in the specific surface area, a decrease in the efficiency of a photocatalyst based on nickel ferrite is observed. In addition, the use of various types of fuels made it possible to obtain aggregates of various shapes and sizes up to several tens of micrometers. The resulting rate constants were established to vary from 0.00756 to 0.00867 min −1 .
