A hydrogen-assisted strategy was introduced to address this issue. Pd was employed as a catalytic site to activate molecular H₂, a green and sustainable reductant, thereby accelerating Fe^III reduction and minimizing sludge formation. UiO-66(Zr), a highly porous metal–organic framework, was utilized as the support to anchor Pd via two distinct configurations: Pd@UiO-66(Zr), where Pd is confined within internal pores, and Pd/UiO-66(Zr), where Pd is deposited on the external surface. The effect of the active center location on the reaction performance was systematically investigated. Mechanistic investigations revealed that singlet oxygen (¹O₂) dominated in the confined Pd@UiO-66(Zr) system, whereas hydroxyl radicals (·OH) were prevalent in Pd/UiO-66(Zr). Under optimal conditions (2 g·L⁻¹ catalyst, 25 μM Fe^II, 20 mM H₂O₂, 30 mL·min⁻¹ H₂, 20 mg·L⁻¹ CBZ), the Pd@UiO-66(Zr) system achieved complete CBZ removal within 30 s, while the Pd/UiO-66(Zr) system required approximately 60 min. After six consecutive cycling tests, no obvious decline in removal efficiency was observed for Pd@UiO-66(Zr), and Pd leaching was nearly undetectable. In contrast, a gradual decrease in removal efficiency was observed for Pd/UiO-66(Zr), accompanied by noticeable Pd leaching. The superior performance of the Pd@UiO-66(Zr) system was attributed to enhanced hydrogen activation, more efficient Fe^II regeneration, and a distinct ROS pathway driven by spatial confinement.</p>\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"40 7","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148174084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A newly synthesized ferrocene-based chemosensor offers highly sensitive Cu²⁺ recognition and biological functionality, enabling simultaneous chemical sensing and cellular imaging. Structural elucidation was achieved using FTIR, HRMS, ¹H NMR, and ¹³C NMR techniques. FSBCS displayed a rapid color transition from brown to orange-red and pronounced spectral changes selectively in the presence of Cu²⁺ ions. The analysis of the Job's plot, coupled with compelling evidence from mass spectrometry and FTIR spectroscopy, unequivocally confirmed a 1:1 binding stoichiometry between FSBCS and Cu²⁺ ions. The complex formation between FSBCS and Cu²⁺ was supported by DFT calculations with Gaussian 16, using the B3PW91 functional and the 6-311+G(d,p) basis set for geometry optimization. The binding constant for the FSBCS–Cu²⁺ complex was determined to be 3.49 × 10⁴. The chemosensor exhibited a detection limit of 4.59 × 10⁻⁸ M and a quantification limit of 15.30 × 10⁻⁸ M.
