In this study, intelligent pH-responsive nanocontainers, termed MBT@HPON, were fabricated using a selective silica etching method, followed by the encapsulation of 2-mercaptobenzothiazole (MBT) through π-π stacking interactions with the organosilica framework. The release kinetics of MBT from the nanocontainers demonstrated that acidic environments reduced the π-π stacking interaction, thereby imparting an acid-responsive release characteristic to the nanocontainers. The total release of MBT reached 69.6% within 24 h at pH = 3, compared to only 14.6% at pH = 7. These nanocontainers were embedded into a silica nanoparticle/methyltrimethoxysilane composite sol-gel coating, creating an intelligent coating system with active and enhanced corrosion protection on 1060 aluminum alloy. Electrochemical impedance spectroscopy analysis indicated that a 0.5 wt% doping content of MBT@HPON exhibited significantly improved electrochemical impedance for the sol-gel coating, with |Z | _f=0.01Hz exceeding 4 × 10⁷ Ω·cm² after 28 d of 3.5 wt% NaCl solution immersion, significantly higher than the pure composite coating. This superior anticorrosive performance can be attributed to the outstanding compatibility between the organosilica shell and the MTMS/silica-based sol-gel coating, along with the active corrosion inhibition from the release of MBT. This work offers valuable insights into the simple construction of sol-gel coatings with enhanced corrosion resistance based on hollow porous organosilica nanocontainers.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":664,"journal":{"name":"Journal of Sol-Gel Science and Technology","volume":"114 2","pages":"447 - 462"},"PeriodicalIF":2.3,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830855","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}

The electrocatalysts were evaluated using several analytical techniques to investigate their crystallinity, surface area and morphology. However, the physical analysis shows that the material has nanoflakes-like morphology which provides effective channels for the transmission of electrons which results in an improved surface area (61.58 m² g⁻¹) as validated via Brunnauer Emmett Teller (BET) measurements.

Thus, the study shows that the Sm-doped AlFeO₃ has the reduced Tafel gradient (32 mV dec⁻¹) and utmost endurance of 40 h, with an overpotential (η) of 188 mV. Moreover, the impedance study supports this concept that prepared material Sm-doped AlFeO₃ has better OER kinetics since it has a low R_ct value (0.26 Ω) which indicates effective charge transmission.

The novel integrated photocatalyst adsorbent system was successfully synthesized from natural bentonite encompassing delamination of the clay layers and an in-situ sol-gel process to load non-metal-doped titanium dioxide on the clay layers. The nanocomposite system thus synthesized was subjected to calcination at 500 °C. Nitrogen doping of the titanium dioxide nanoparticles in the modified nanocomposite system was enabled via chitosan precursor addition. The structural, morphological, and functional features of the synthesized nanocomposites were further evaluated using different characterization techniques such as Fourier Transform Infrared (FTIR) analysis, UV-visible spectral analysis, X-ray Diffraction analysis (XRD), X-ray photoelectron spectroscopy (XPS) analysis, Brunauer-Emmett-Teller Surface Area (BET) analysis, Scanning Electron Microscopic (SEM) analysis, and Atomic Absorption Spectrophotometric (AAS) analysis. The nanocomposite was then tested for its efficiency in the degradation of an organic dye, methylene blue, and for the adsorption of heavy metal ions (Cu) from model-contaminated water. A high photocatalytic efficiency of 93% was achieved by the nanocomposite when tested against aqueous methylene blue dye (10^-5 M) under UV light for about 1 h. The adsorption capacity of the nanocomposite in removing Cu²⁺ ions from model-contaminated water was found to be 13.82 mg g^-1 at optimal conditions of pH 6.0, initial concentration of 10 ppm, and adsorbent dosage of 0.05 g. The photocatalytic efficiency and adsorption capacity of the nanocomposite towards the removal of dyes and heavy metal ions from water could be attributed to the small size of the nitrogen-doped titanium dioxide nanoparticles ( ~ 7 nm) in the nanocomposite which provides an enhanced surface area of 131.2 m²g^-1.

X-ray diffraction (XRD) analysis confirms a hexagonal wurtzite structure, demonstrating the successful incorporation of Bi atoms into the ZnO lattice. Refinement results indicate that both the lattice parameters and unit cell volume increase with higher Bi content. X-ray peak broadening analysis was performed using the Debye-Scherrer and Williamson-Hall (W-H) methods to evaluate the crystallite size and lattice strain. Impedance spectroscopy measurements were carried out over a frequency range of 40 Hz to 10⁷ Hz and a temperature range of 320 K to 410 K to assess the influence of frequency and temperature on the dielectric properties of the synthesized samples. Comparative Nyquist plots at a fixed temperature of 320 K revealed a decrease in impedance with increasing Bi doping concentration. This reduction in impedance is associated with an increase in electrical conductivity and a decrease in relaxation time, confirming that Bi doping enhances conductivity at 320 K. Furthermore, the improved electrical conductivity suggests that the material could facilitate electron transfer, making it a promising candidate for humidity and gas sensing applications. Additionally, dielectric characterization confirmed that the dielectric constant increases with higher Bi doping levels. The observed high permittivity values recommend the synthesized Bi₀.₀₀₇Zn₀.₉₈₉₅O compound for potential use in high-frequency devices. A more in-depth study of the structural, electrical, and dielectric properties demonstrates that Bi-doping effectively modulates the structural, electrical, and dielectric characteristics of ZnO nanostructures.
