Hence, a novel efficient ZCS/Cu3P/AgCl adsorption-photocatalyst is synthesized and characterized by various testing methods. The efficient removal of dye Rh B is achieved through a synergistic effect between adsorption and photocatalytic degradation. Photocatalytic experiments showed that all the ZCS/Cu3P/AgCl composites with different AgCl content exhibit superior photocatalytic activity for Rh B degradation, and when the content of AgCl is 31%, the photocatalytic activity is the best. After 30 min of dark adsorption, 30% of Rh B was removed by adsorption, and 98.76% of Rh B was removed after continuous visible light irradiation for 20 min. The kinetic constant of 31%-ZCS/Cu3P/AgCl composite was 0.346 min–1, which is about 24.7 and 3.8 times that Cu3P (0.014 min–1) and AgCl (0.091 min–1), respectively. Moreover, photo-luminescence and photoelectrochemical experiment confirmed that the surface of ZCS/Cu3P/AgCl is exposed to more active sites, the charge separation process is enhanced and the photogenerated electron–hole recombination efficiency is reduced compared with Cu3P and AgCl. Finally, h+ and ·O(_{2}^{ - }) are identified the main active species in the photocatalytic reaction system, and a possible photocatalytic mechanism was put forward. ZCS/Cu3P/AgCl composites have excellent photocatalytic performance and recyclability, and are expected to be an important material to solve dye pollutants in water.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"35 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141551815","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}

The dissociation constants of the ligand PAR are calculated together with the stability constants of its complexes with the above metal ions. The experimental conditions are controlled to achieve all measurements required in the solution (ethyl alcohol (10%) and water (90%)) at (25 ± 0.1)°C and an ionic background of 0.1 mol dm–3 NaCl. The ligand acts as a tri-dentate, coordinating through the pyridine nitrogen, one of the azo group nitrogen and the ortho-hydroxy of the resorcinol moiety. Four dissociation constants were identified experimentally with values 2.40, 3.34, 5.63, and 10.84. It has been observed that several metal complexes originated in the solution, under the mentioned experimental conditions for each metal ion used. The values of the overall stability constants log ßn for all species and the dissociation constants of the PAR ligand are determined using the HYPERQUAD-2008 computer program. All species present in the solution are displayed with the use of speciation diagrams.","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"25 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141551848","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}

The uranium-containing structural units are complexes [UO2(C2O4)F3]3– (for I and II), [UO2(C2O4)2F]3– (III), and [UO2(C2O4)F]– (IV) with crystal chemical formulas А(В01)M(_{3}^{1}), А(В01)2M1, and А(Q02)M1 (A = ({text{UO}}_{{text{2}}}^{{{text{2 + }}}}); B01 or Q02 = ({{{text{C}}}_{{text{2}}}}{text{O}}_{{text{4}}}^{{2 - }}); M1 = F–), respectively.

The results obtained suggest that the sharp increase in the solubility of uranyl oxalate trihydrate in aqueous solutions with the addition of fluorides is due to the effect of structural depolymerization of coordination polymers in the presence of fluoride ions.

The elastic constants, bulk modulus, shear modulus; Young’s modulus, Pugh’s ratio, and Poisson’s ratio have also been computed. The studied compounds are thermodynamically stable, and their stability decreased with the increase of atomic radius. Pugh’s and Poisson’s ratios that were calculated show that Li2TiBr6 and Na2TiBr6 are ductile compounds.
