The precursors included polyvinyl alcohol or glycine. The intensity of charge generation was lower for precursors containing a larger amount of the organic component. Magnetic characteristics of the samples (magnetization, coercive field) were measured. An external magnetic field applied during the hexaferrite synthesis significantly affected the coercive field of the samples, which could be increased via the formation of extended ensembles of nanoparticles. The effect was more pronounced for samples with a moderate level of charge generation. The relationship between the factors influencing the formation of extended aggregates was analyzed. The maximum coercive field was found for Sr0.8La0.2Fe11.8Co0.2O19. One way to increase the coercive field is a two-stage magnetic heat treatment including a low-temperature stage. The formation of branched extended structures at the macro- and micro-levels was found during the combustion of glycine-containing precursors.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"27 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141551849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these materials have fast electron–hole relaxation times, which reduces their activity in photoreactions. Hybrid ferrite-based nanostructures, for example, composites with zinc oxides, can help to overcome the problem. The catalytic activity of such a structure depends highly on the method by which it was prepared. In this work, we used the alkali coprecipitation of Fe2+ and Ni2+ ions, whose hydroxides have similar values of solubility products (SPs), to prepare the most stoichiometric and structurally and compositionally homogeneous nickel ferrite precursor. The influence of the reaction parameters on the purity and particle size of the nickel ferrite phase was studied using experiment and data processing design. Spherical nanoparticles of 15.9 ± 1.1 nm in diameter were produced under the identified optimal conditions. The prepared material was used to manufacture various NiFe2O4/ZnO magnetic composites. The photocatalytic activity of the hybrid structures was shown in photodegradation of the Crystal Violet dye.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"6 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141551847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
