It has been found that, in addition to the ferrospinel phase (a = 8.329 ± 0.001 Å), the product contains 9.6 wt % of α-Fe2O3. The presence of this impurity does not hinder the effective magnetic separation of the material from the reaction medium. The influence of sacrificial agents (Sodium citrate, carbonate, bicarbonate, and hydrogen peroxide) on the photocatalytic degradation of indigo carmine in the presence of NiFe2O4 under UVA irradiation (λ = 340 nm) has been systematically investigated for the first time. It has been demonstrated that only addition of hydrogen peroxide at concentration of 0.01 mol/L leads to a significant enhancement of the process (up to 70% degradation within 60 min). Scavenging experiments with reactive oxygen species (ROS) revealed that singlet oxygen plays a major role in the oxidation of Indigo Carmine. These findings extend the current understanding of photocatalytic mechanism on ferrospinels and confirm the potential of NiFe2O4 for application in wastewater treatment.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"71 7","pages":"1019 - 1028"},"PeriodicalIF":1.5,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148859871","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}

It was determined, that in these systems, silver(I) ions form complexes of the composition AgLo and ({text{AgL}}_{2}^{ - }) with the aliphatic amino acids used. Based on the calculated numerical values of the protonation constants of individual aliphatic amino acids, as well as the stability constants of the complexes formed from them, patterns in the influence of the electron effects of amino acid side chains on the stability of complex particles in aqueous media were established.

The optimal dopant concentrations that provided the highest afterglow intensity and duration were 1.0 at % Eu2+ and 2.0 at % Dy3+. The K+ and Na+ (1.0 at % each) charge-compensator ions increased the afterglow time up to 10 min due to their efficient incorporation into the strontium sublattice. The substitution of boron for aluminum (8–30 at %) did not change the phase composition, but significantly increased the afterglow duration: for a 15 at % boron sample, the afterglow time amounted to 60 min, which exceeds the documented values for similar compositions. The phase composition of the samples was a mixture of luminescent phases (Sr4Al14O25, SrAl2O4, and SrAl12O19) and nonluminescent compounds; a single-phase product was not a prerequisite for long-lasting afterglow to be achieved. The photoluminescence spectra featured a broad band in the range 450–600 nm with a peak at about 520 nm, corresponding to 4f 65d1 → 4f 7 (8S7/2) transitions in Eu2+ ions in various crystal environments. The luminescence was excited by 365-nm UV radiation.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"71 7","pages":"892 - 904"},"PeriodicalIF":1.5,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148859819","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}
