Ultrasensitive and Wide-Range Electrochemical Sensor for Acetaminophen Based on a “Three-In-One” Engineered MOF (Fe)@Fe3S4/CNF Platform
This study presents a novel ternary heterostructured electrochemical sensor (MOF (Fe)@Fe3S4/CNF) by integrating Fe-MOFs, Fe3S4, and carbon nanofibers (CNF) for ultrasensitive acetaminophen (APAP) detection. Fe3S4 was anchored in situ on Fe-MOFs via ultrasound-assisted hydrothermal vulcanization, coupled with 3D CNF networks. Characterization (XRD, FT-IR, SEM, XPS, and BET) confirmed Fe3S4 enhances the MOF electronic configuration via interfacial charge redistribution, while CNF prevents aggregation and boosts conductivity. The optimized sensor shows a wide linear range (0.02–350 μM, R2 = 0.9993), ultralow LOD (9.583 nM), > 94% interference resistance (UA, DA), and high recovery (97.33%–104.4%). A triaxial synergy mechanism is proposed: (1) MOF mesopores enable size-selective APAP diffusion, (2) Fe2+/Fe3+ redox pairs drive catalytic activation via Jahn-Teller effects, and (3) CNF ensures efficient charge transfer. This “pore-activity-conductivity” strategy advances MOF-based sensors through structural precision and interfacial nanoscale engineering for next-gen electrochemical platforms.
期刊介绍：
All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
