This study emphasizes the removal of cationic dye employing batch experiments utilizing ferric–biochar–bimetallic nanocomposites prepared using a green synthesis approach. The innovation lies in the utilization of biochar extract derived from carrot waste materials as reducing agents to synthesize iron nanoparticles (Zn/nZVI, Ca/nZVI, Cu/nZVI, Ba/nZVI, and native). It was found that the optimum pH for reactive blue dye removal fell within the basic range, specifically at a range of 8, 9, and 10 at 0.05 g catalyst dosage, 90 min contact time, 65 °C temperature, and 150 mg/L initial dye concentration. The maximum adsorption capacities were calculated as follows: Zn (44.92984), Ca (33.9921), Cu (39.13628), Ba (30.86284), and native (42.43492). Langmuir biosorption isotherms provided the best fit for equilibrium biosorption data, while the pseudo-second-order model demonstrated reasonable fit for biosorption kinetic data. Various thermodynamic factors including enthalpy, free energy, and entropy were investigated to assess the suitability and fitness of the biosorption process. Furthermore, the impact of different electrolyte concentrations on the biosorption potential was examined. It was found that the biosorption ability of selected ferric–biochar–bimetallic nanocomposites for anionic dye was significantly reduced in the presence of surfactants/detergents.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 2","pages":"1113 - 1135"},"PeriodicalIF":2.2,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Instead, various composites are proposed where intimate contact between two phases creates heterojunction, that improves photoactivity. Another challenge is morphology development. Heterogeneous photocatalyst must have an increased surface exposed to a reaction mixture to create structural prerequisites for better reagent diffusion, and photoseparated charges migration. Nanostructured materials meet these requirements. Being composed of smaller structures assembled regularly, nanostructures exhibit higher specific surface and well-developed pores, making them appealing substrates for photocatalysts. Problem is they are hard to get with conventional synthetic protocols. Recently emerged poly(triazine imide) as a non-metal based semiconductor proved applicable in photocatalysis, yet showed compromised selectivity. In pursuit of more selective catalysis, it was subjected to coupling with transition metal oxide. As a result, we developed a novel grain-like nanostructure of photoactive composite based on poly(triazine imide) (PTI) and anatase, which was efficient in benzyl alcohol (BA) oxidation and provided targeted benzaldehyde (BAl) with 94% selectivity at 100% conversion.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 2","pages":"1103 - 1112"},"PeriodicalIF":2.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five strains were isolated for degradation studies: PDB-2, PDB-3, PDB-5, PDB-7, and NB-3. The Strain PDB-2 demonstrated the best degradation and was selected for further studies, henceforth referred as VSH PD-02. Further the fungal isolate VSH PD-2 was subjected to molecular identification based on 18S rRNA sequences and homology analysis, which showed the closest homology toward <i>Talaromyces aerugineus.</i> This study was aimed to develop a conceptual model for the biological degradation of plastic by microbes. The results of FTIR showed significant difference in molecular bonding after degradation period of 30 days. This research suggests that the polyethylene plastic material has undergone degradation due to the activity of the enzymes produced by these microorganisms. In conclusion, the study on plastic biodegradation by microorganisms, exemplified by <i>Talaromyces aerugineus</i> VSH PD -02 fungi, offers valuable insights with relevance to bioremediation.
