The formation of electric charges during the synthesis of complex oxide materials based on strontium hexaferrite SrFe12O19, including doped with lanthanum and cobalt ions, via the combustion of nitrate-organic precursors has been established. Precursors included polyvinyl alcohol or glycine as organic component. The intensity of charge generation was lower for precursors containing a larger amount of organic component. Data on the magnetic characteristics of the samples were obtained: magnetization, coercive force. The influence of an external magnetic field during the synthesis of hexaferrites significantly affected the coercive force of the samples and allowed to increase its values due to the formation of extended ensembles of nanoparticles. At the same time, such an effect on samples with a relatively low level of charge generation during precursor combustion was more effective. The relationship between the factors influencing the formation of extended aggregates is analyzed. The Sr0.8La0.2Fe11.8Co0.2O19 samples had the maximum coercive force. One of the techniques for increasing the coercive force is a two-stage thermomagnetic 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.
在通过燃烧硝酸盐有机前驱体合成基于六价铁锶 SrFe12O19 的复合氧化物材料(包括掺杂镧和钴离子)的过程中,电荷的形成已经得到证实。前驱体包括作为有机成分的聚乙烯醇或甘氨酸。有机成分含量较高的前驱体产生电荷的强度较低。获得了样品的磁性特征数据:磁化率、矫顽力。在合成六铁氧体的过程中,外部磁场的影响对样品的矫顽力有显著影响,由于纳米颗粒形成了扩展的集合体,矫顽力值得以提高。同时,这种影响对在前驱体燃烧过程中电荷生成水平相对较低的样品更为有效。分析了影响扩展集合体形成的因素之间的关系。Sr0.8La0.2Fe11.8Co0.2O19 样品的矫顽力最大。增加矫顽力的技术之一是两阶段热磁处理,包括低温阶段。在含甘氨酸前驱体的燃烧过程中,发现在宏观和微观层面形成了支化扩展结构。

Crystal structure Na3[UO2(C2O4)F3] · 4H2O (I), K3[UO2(C2O4)F3] (II), K3[UO2(C2O4)2F] · 3H2O (III) and Cs[UO2(C2O4)F] · H2O (IV) first studied by X-ray diffraction. Uranium–containing structural units are complexes [UO2(C2O4)F3]3ˉ (for I and II), [UO2(C2O4)2F]3- (III) and [UO2(C2O4)F]- (IV), accordingly with crystal chemical formulas А(В01)M13, А(В01)2M1 and А(Q02)M1, where A = UO22+, B01 or Q02 = C2O42-, and M1 = F- . In all compounds U(VI) atoms implement pentagonal-bipyramidal coordination, at that in I—III uranyl complexes have single–core structure, and in IV crystals–chain structure which is similar for the well — known for [UO2(C2O4)(H2O)] · 2H2O. The obtained results suggest that a sharp increase in the solubility of uranyl oxalate trihydrate in aqueous solutions with the addition of fluorides is due to the well-known effect of structural depolymerization of coordination polymers of d- or f-metals in the presence of fluoride ions. Semi-empirical calculation and comparison of calculated and experimental oscillation frequencies in IR spectra II and IV are carried out.

Copper (II) oxide nanoparticles are promising materials for applications in catalysis, biomedicine and photovoltaics. It is also possible to use them for the preparation of nanocomposites and hybrid nanoparticles. This work presents a new method for the synthesis of CuO nanoparticles, which allows their one-step preparation without washing and heating. The proposed anion-exchange deposition method is simple, fast and easily reproducible under normal laboratory conditions. It is shown that anion-exchange precipitation of copper in the presence of the polysaccharide dextran-40 from copper chloride and sulphate solutions produces well crystallised hydroxychloride Cu2Cl(OH)3 and hydroxysulphate Cu4(SO4)(OH)6, respectively, and from copper nitrate a weakly crystallised Cu(OH)2 phase. In the absence of polysaccharide, copper oxide nanoparticles are formed irrespective of the nature of the anion of the parent salt. The obtained materials were used to obtain hydrosols with high aggregation and sedimentation stability over a wide pH range (from 5 to 11). These sols are stable for more than 3 months at a concentration of 2 g/l (the average hydrodynamic diameter of the particles is 245 nm; the average ζ-potential is -31.1 mV). Based on the study of the optical and electronic properties of the obtained hydrosols, it was found that they could be of interest for photocatalysis and application in optoelectronic devices.
纳米氧化铜(II)粒子是一种在催化、生物医学和光伏领域应用前景广阔的材料。它们还可以用于制备纳米复合材料和混合纳米粒子。本研究提出了一种合成氧化铜纳米粒子的新方法,该方法无需清洗和加热,可一步制备。所提出的阴离子交换沉积法简单、快速,而且在正常实验室条件下易于重复。研究表明,在多糖 dextran-40 的存在下,阴离子交换沉淀法从氯化铜和硫酸铜溶液中沉淀铜,可分别生成结晶良好的羟基盐酸盐 Cu2Cl(OH)3 和羟基硫酸盐 Cu4(SO4)(OH)6,而从硝酸铜中沉淀铜,则可生成结晶较弱的 Cu(OH)2 相。在没有多糖的情况下,无论母盐阴离子的性质如何,都会形成纳米氧化铜颗粒。所获得的材料可用于获得在较宽 pH 值范围(从 5 到 11)内具有较高聚集和沉淀稳定性的水溶胶。这些溶胶在 2 克/升的浓度下可稳定 3 个月以上(颗粒的平均流体力学直径为 245 nm;平均ζ电位为 -31.1 mV)。根据对所获水溶液的光学和电子特性的研究,发现它们可用于光催化和光电设备。

Ferrites of non-ferrous metals are promising magnetic catalysts that can be easily separated from the reaction mixture after use by applying a magnetic field. However, these materials have a fast electron-hole relaxation time, which reduces their activity in photoreactions. This problem is overcome by creating hybrid nanostructures based on ferrites, for example with zinc oxides. The catalytic activity of such structures depends highly on the method of their synthesis. In this work, the alkaline co-precipitation of Fe2+ and Ni2+ ions, which have similar values for hydroxides, was used to obtain stoichiometric and homogeneous nickel ferrite precursors. The influence of the reaction parameters on the purity of the nickel ferrite phase and the size of the particles was studied using the experimental design technique. Spherical nanoparticles 15.9 ± 1.1 nm in diameter were produced under the optimal conditions identified. Based on the obtained material, NiFe2O4/ZnO magnetic composites of different quantitative compositions were prepared. The photocatalytic activity of the hybrid structures was demonstrated by photodegradation of crystal violet dye.
有色金属铁氧体是一种很有前途的磁性催化剂,使用后只需施加磁场,就能很容易地从反应混合物中分离出来。然而,这些材料的电子-空穴弛豫时间较快,从而降低了它们在光反应中的活性。克服这一问题的方法是创建基于铁氧体(例如与氧化锌)的混合纳米结构。这种结构的催化活性在很大程度上取决于其合成方法。在这项工作中,利用氢氧化物具有相似值的 Fe2+ 和 Ni2+ 离子的碱性共沉淀,获得了化学计量且均匀的镍铁氧体前驱体。利用实验设计技术研究了反应参数对镍铁氧体相纯度和颗粒尺寸的影响。在确定的最佳条件下,生成了直径为 15.9 ± 1.1 nm 的球形纳米颗粒。根据所获得的材料,制备了不同定量成分的 NiFe2O4/ZnO 磁性复合材料。混合结构的光催化活性通过对水晶紫染料的光降解得到了证明。

Zn(II) complexes of the composition [ZnLn2X2] and [ZnLn3(NO3)2] were synthesized, where n = 1, 2; X=Cl, Br, I; L1=2-aminothiadiazole-1,3,4, L2=2-amino-5-methylthiadiazole-1,3,4. The obtained complexes were studied by elemental analysis methods, IR and 1H NMR spectroscopy. The structure of the [ZnL22Br2] complex was determined by the RSA method (CIF file CCDC No. 2251742). The ligand molecules of 2-amino-5-R-thiadiazoles-1,3,4 (R = –H, –CH3) are coordinated monodentately by an endocyclic nitrogen atom located in the α-position to the amino group. The polyhedron of the central atom of halide complexes is a slightly distorted tetrahedron, in the coordination sphere of which two halide atoms and two endocyclic nitrogen atoms are located. During complexation in the spectrum of the solution of the [ZnL22Br2] complex, coordinated L2 ligands undergo amino-imine tautomerization into a heterocyclic amine with a nitrogen atom in a heterocycle. The polyhedron of the central atom for nitrate complexes is a slightly distorted trigonal bipyramide, in the coordination sphere of which three nitrogen atoms of ligands are located in the equatorial plane and two oxygen atoms of two nitrate anions in the axial position.

The polyhedron of the central atom for nitrate complexes is a slightly distorted trigonal bipyramide, in the coordination sphere of which three nitrogen atoms of ligands are located in the equatorial plane and two oxygen atoms of two nitrate anions in the axial position.","PeriodicalId":360124,"journal":{"name":"Журнал неорганической химии","volume":"5 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141797154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zinc sulfide doped with Mn2+ ions was synthesized in a homogeneous dodecane medium by the method of emerging reagents. By methods of chemical and X-ray phase analysis, IR spectroscopy, electron microprobe microscopy, identification of products was carried out, photographs of the surface of powder particles (SEM) were recorded. Based on the totality of the results, a conclusion is made about the formation of nanoscale objects having a polytype structure with a predominance of distorted cubic crystals forming agglomerates up to 10 microns in size in ZnS powder and up to 100 microns in ZnS–Mn powder. The formation of nanoscale ZnS particles is confirmed by spectral data. The effect of manganese ions on the photoluminescence (FL) of the powder is manifested by a change in the type of the descending branch of the ZnS–Mn FL band, it is associated with recombination processes at the levels of defects formed by Mn2+ ions in the ZnS structure at their low concentration.
采用新出现的试剂方法,在均相十二烷介质中合成了掺杂 Mn2+ 离子的硫化锌。通过化学和 X 射线相分析、红外光谱、电子显微镜等方法对产品进行了鉴定,并记录了粉末颗粒表面的照片(SEM)。根据所有结果得出结论,纳米级物体的形成具有多型结构,在 ZnS 粉末中主要是扭曲的立方晶体,形成的团块大小可达 10 微米,在 ZnS-Mn 粉末中可达 100 微米。光谱数据证实了纳米级 ZnS 颗粒的形成。锰离子对粉末光致发光(FL)的影响表现为 ZnS-Mn FL 波段下降分支类型的变化,这与低浓度 Mn2+ 离子在 ZnS 结构中形成的缺陷水平上的重组过程有关。
