All the compounds crystallised in the orthorhombic crystal system with Pnma space group. Single crystal study indicated that Co substitute at the Pb-site in Pb1−xCoxSnS3 in a disordered manner. The structure of Pb1−xCoxSnS3 compounds contains edge shared bi-octahedral chains of SnS6 and zig-zag chains of (Pb/Co)S running along b-direction. XPS study indicates that cobalt exists as Co2+ while tin and sulphur remain as Sn4+ and S2− respectively. Magnetic susceptibility studies on Pb1−xCoxSnS3 (x = 0.1, 0.2 and 0.40) suggest ferromagnetic ordering below 125 K. The Pb/Co-S-Pb/Co bond angle (88.6°) in the Pb/Co-S chains is very close to 90° suggesting ferromagnetic ordering in these compounds, which corroborate the magnetic susceptibility results. As the amount of Co substitution increases, the magnetic susceptibility values gradually increases as evident from the M-T curves, which is attributed to substitution of more Co2+ at the non-magnetic Pb2+ site in Pb1−xCoxSnS3. The M − H isotherms reveal saturation magnetic moment that is smaller than the expected value, possibly due to disorder of the magnetic ions in these compounds. However, neutron diffraction study is required to completely understand the detailed magnetic properties in these compounds.</div></div>","PeriodicalId":432,"journal":{"name":"Solid State Sciences","volume":"160 ","pages":"Article 107818"},"PeriodicalIF":3.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143149343","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}

In this regard, CoxZn1-xSe (x = 0.00, 0.03, and 0.06 wt %) QDs were synthesized using a typical hydrothermal method to provide an easier, workable, affordable way to remove antibiotic pollutants from wastewater. Doping of magnetic impurities (Co2+ ions) in ZnSe QDs transformed the systems into diluted magnetic semiconductors and a signature of weak ferromagnetic behavior was registered at ambient temperature. Therefore, the genesis of weak ferromagnetism in doped systems has also been studied using DFT calculations to flourish their potential use for spintronic devices. Incorporation of cobalt ions introduced weak ferromagnetic signature at 300 K in doped ZnSe QDs, which is ascribed to the p-d hybridization as given by the DFT calculations. Photocatalytic degradation of ciprofloxacin (CIP) antibiotic agent was studied thoroughly by varying pH, temperature and the dosages of doped ZnSe nanocatalysts. It was found that 6 % cobalt-doped ZnSe QDs showed relatively better efficiency and rate constant in degrading CIP. With the increase in temperature (up to 70 °C), a significant increment in both the reaction rate and efficacy was observed for the highest Co-content ZnSe nanocatalysts.

Detailed characterization demonstrated that PCS has a substantial specific surface area (301.6 m2 g−1) and C-P-O groups (not in pristine biochar). Adsorption experiments were better described by pseudo-second-order and Langmuir model, which indicated that the adsorption followed the physicochemical diffusive monolayer adsorption mechanism.
