This study focused on the development of a ferric oxide/titanium silicalite (Fe₂O₃/TS-1) to activate PMS to degrade tetracycline hydrochloride (TC). The optimized 14% Fe₂O₃/TS-1 achieves the TC removal efficiency of 99.2% within 1 h. It mainly results from the adsorption-degradation synergy of Fe₂O₃/TS-1, where TS-1 has a strong adsorption ability for TC and Fe₂O₃ provides an abundance of active sites for the generation of free radicals by activating PMS. These techniques indicate the involvement of both radical species (SO₄^⋅−, ⋅OH and O₂^⋅−) and non-radical species (¹O₂) in the process. Notably, O₂^⋅− emerged as a pivotal player in the degradation of TC. The effect of coexisting anions (Cl⁻, NO₃⁻, SO₄²⁻ and HCO₃⁻) confirms that Fe₂O₃/TS-1 is still effective in complex water. Three degradation pathways are confirmed by liquid chromatography-mass spectrometry (LC–MS). Recycling experiments and toxicity evaluation experiments show that the Fe₂O₃/TS-1 composite catalyst is stable and efficient, and the leaching concentration of iron is much lower than that in the normal range. This study shows the application prospect of the Fe₂O₃/TS-1 + PMS system in the degradation of refractory organic pollutants.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"155 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865412","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}

One possible method for removing organic and inorganic contaminants from wastewater is heterogeneous photocatalysis. Hence, in this work, we have successfully synthesized CuSe, ZnO, and their heterostructure nanocomposite by utilizing a simple and cost-effective hydrothermal method. A range of characterization techniques, including XRD, XPS, FT-IR, SEM/EDS and UV-Vis spectroscopy analysis were employed to further understand the structure, morphology, composition and optical characteristics of the synthesized samples. The band gap energy for CuSe, ZnO, and CuSe/ZnO samples were obtained to be 2.14, 2.85, and 2.36 eV, respectively. The synthesized nanocomposite was used to test the photocatalytic degradation of two model dye pollutants Crystal violet and Rose bengal as a function of optimized operational parameters viz., dye concentration (15 mg/L for crystal violet and 10 mg/L for rose bengal), catalyst dose (50 mg), illumination time (125 min) and pH (9 for crystal violet and 6 for rose bengal). The findings of this study demonstrated that CuSe/ZnO heterostructure nanocomposite has shown excellent photocatalytic dye degradation performance. At optimized parameters, the degradation efficiency for crystal violet and rose bengal dyes was achieved to be 94.13% and 90.86%, respectively.

A Y-Hβ catalyst with dual-acid functionality and hierarchical pore structure was successfully constructed by precisely introducing yttrium ions (Y³⁺) into the Hβ zeolite framework through an equal-volume impregnation method. Structural characterization confirms that Y³⁺ is anchored in the framework as [YO₄] tetrahedra, establishing strong Lewis acid sites while maintaining the structural integrity of Hβ zeolite. Mechanistic studies reveal that Y³⁺ promotes C = O bond cleavage in anhydride molecules through adsorption polarization to generate C⁺ intermediates, while simultaneously enhancing the proton acidity of adjacent Brønsted acid sites via electronic induction effects. Under Lewis acid regulation, neighboring Si-OH-Al sites precisely donate protons to the α-position of anthraquinone, forming C₁₀H₇⁺ intermediates. The synergistic cooperation between dual acids reduces the acylation reaction energy barrier to 32.8 kcal/mol (a 24.1 kcal/mol reduction compared to Hβ zeolite), significantly accelerating reaction kinetics. Under optimized conditions (250 °C, 5 h), the reaction achieves 82.6% conversion and 80.6% selectivity, demonstrating 50.6% improvement in catalytic efficiency over Hβ zeolite. Regeneration tests verify that the Y-Hβ catalyst maintains over 90% initial activity after 5 cycles, attributed to the high stability of Y-O-Si bonds and exceptional anti-coking performance, highlighting its promising industrial application potential.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"155 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143856663","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}
