This study introduces a bifunctional polyaniline-chitosan (PANI-Ch) nanocomposite, synthesized via in-situ oxidative polymerization, designed for the high-capacity adsorption and quantitative optical detection of the pesticide Sumithion. The PANI-Ch platform exhibited an exceptional adsorption capacity of 124.7 mg/g, following a Langmuir-type monolayer process. Thermodynamic and spectroscopic analyses revealed a physisorption mechanism dominated by π–π stacking and hydrogen bonding, supported by a mean free energy (E) of 0.027 kJ/mol. Beyond remediation, the nanocomposite functions as a robust sensing tool; Sumithion adsorption induces precise, concentration-dependent FTIR spectral shifts in the O–H/N–H and C = C stretching regions. These optical changes allow for trace-level quantification with a Limit of Detection (LOD) of 0.5 ppb. By integrating high efficiency scavenging with built-in analytical signaling, this nanocomposite provides a versatile and advanced platform for integrated water treatment and real-time environmental monitoring.</p>\u0000 </div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"33 3","pages":"941 - 952"},"PeriodicalIF":3.0,"publicationDate":"2026-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10934-026-01918-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148292256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following a two-step anodization process, planar Al substrates developed a porous layer confined to the flat surface. In contrast, Al wire, owing to their curved geometry, experienced an enhanced local electric field, resulting in thicker oxide layers distributed around the circumference. The most pronounced effect was observed in hollow Al tubes, where nanoporous layers formed simultaneously on both the inner and outer surfaces. This dual-surface anodization significantly increased the effective surface area and produced the thickest oxide layers among all substrates studied. Field-emission scanning electron microscopy was employed to characterize the AAO morphology. The results revealed a direct correlation between the applied voltage and AAO pore diameter, with pore sizes increasing from 30.0 to 150.0 nm for planar substrates and from 30.0 to 220.0 nm for non-planar substrates as the voltage increased from 40 V to 100 V. The AAO thickness ranged from 12.7 to 47.0 μm for planar substrates and from 14.0 to 60.0 μm for non-planar substrates. Additionally, the surface geometry of the Al substrates influenced the distribution of AAO pore diameters. The dual-layer AAO on Al tubes exhibited larger pores and greater interpore distances, which are attributed to differences in oxide growth direction and electrochemical field distribution.

To get around this problem, a new hybrid counter electrode made of biocarbon and cerium oxide/cobalt oxide (BC@CeO₂/Co<sub>3</sub>O<sub>4</sub>) was made utilizing a simple hydrothermal technique. This combined arrangement used thin biocarbon nanosheets to cover evenly spaced cubic CeO₂ and Co<sub>3</sub>O₄ nanoparticles, which made a tightly packed and interrelated nanostructured assembly. Using XRD, FTIR, FESEM, and TEM to look into the structure and form showed that CeO₂ and Co<sub>3</sub>O₄ crystalline phases may exist together without any noticeable lattice distortion. XPS spectra showed mixed oxidation states of Ce<sup>3+</sup>/Ce<sup>4+</sup> and Co<sup>3+</sup>/Co<sup>3+</sup>, which has implications for speeding up redox reactions at the electrode-electrolyte junction. The BET surface area analysis showed that the BC@CeO₂/ Co<sub>3</sub>O₄ composite was much better than the CeO₂/ Co<sub>3</sub>O₄ composite, with a value of 112.5 m<sup>2</sup> g<sup>− 1</sup>. Because the material’s average pore diameter was about 3.5 nm, there were many places where ions could move and electrolytes could diffuse. Different electrochemical tests, like CV, Tafel, and EIS, have shown that BC@CeO₂/ Co<sub>3</sub>O₄ has a good charge-transfer efficiency. This is obvious from the low charge-transfer resistance (Rct = 1.95 Ω), low series resistance (Rs = 0.52 Ω), and high double-layer capacitance (Cdl = 36.7 mF cm<sup>− 2</sup>). The readings for the CeO₂/ Co<sub>3</sub>O₄ electrode (Cdl = 12.5 mF cm<sup>− 2</sup>) are much lower. The DSSC with the BC@CeO₂/ Co<sub>3</sub>O₄ counter electrode has a power conversion efficiency (PCE) of 8.5%, which is higher than the CeO₂/Co<sub>3</sub>O₄ (5.6%) and the conventional Pt-based device (6.7%). The BC@CeO₂/ Co<sub>3</sub>O₄ electrode improves redox kinetics, speeds up the flow of electrons, and makes charge transfer more efficient at the interfacial boundary. This leads to excellent photovoltaic efficiency and long-term stability.

XRD analysis suggest that nanocrystalline and tetragonal with anatase phase. The SEM images revealed well-defined nanosheet structures with a relatively uniform distribution. The lateral dimensions of the TiO₂ nanosheets ranged from approximately 80 to 150 nm, with an average diameter of 115 ± 15 nm. Their multifunctional potential was systematically evaluated in dye-sensitized solar cells (DSSCs), photocatalysis, and electrochemical energy storage. As a DSSC photoanode, the TiO₂ nanosheets achieved a photo conversion efficiency (PCE) of 8.42 ± 0.05% with <i>Jsc</i> = 16.57 mA cm⁻², <i>Voc</i> = 748 mV, and <i>FF</i> = 0.72, surpassing commercial P25-based devices. In photocatalytic degradation studies under solar light, the material showed broad-spectrum activity, achieving degradation efficiencies of 85% for methylene blue (MB), 75% for methyl red (MR), 99% for Rhodamine B (RhB), and 70% for malachite green (MG) along with excellent recyclability and stability. Furthermore, in an asymmetric supercapacitor (ASC) with TiO<sub>2</sub> as positive and activated carbon (AC) as negative electrode, which delivered a specific capacitance of 296.2 F/g at 1 A/g, an energy density of 52.5 Wh/kg at 800 W/kg, and retained 98% capacity after 10,000 cycles. These results highlight the sustainable and multifunctional nature of Rosmarinus officinalis-derived TiO₂ nanosheets, demonstrating their strong potential in solar energy harvesting, environmental remediation, and high-performance energy storage applications.</p></div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"33 2","pages":"801 - 814"},"PeriodicalIF":3.2,"publicationDate":"2026-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147743652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
