In this study, a cost-effective graphite aerogel was fabricated using the directional freeze-drying method for integrated thermal insulation-thermoelectric applications across a wide temperature range. A pioneering Voronoi diagram-based electrical conductivity model featuring fractal lamellar structures was proposed with below 5% deviation between simulation and experimental data, which enables analysis of electrical transport properties under different densities of the lamellar structure, providing in-depth mechanism analysis of the interplay between microstructure and thermoelectric performance. By modulating the oriented lamellar skeletal structure, this aerogel achieved an efficient electrical carrier transportation of 48.28 S·cm⁻¹ and an effective suppression of thermal conductivity to 0.585 W·m⁻¹·K⁻¹ at 923 K. Remarkably, the aerogel exhibits a 2–3 orders of magnitude enhancement in cost-normalized electrical conductivity over current-generation thermoelectric aerogels. Due to the band degeneracy effect, the Seebeck coefficient shows a significant increase when the temperature exceeds 773 K and reaches 96.84 μV·K⁻¹ at 923 K.

As a result, ZnAl–LDH/Bi₄O₅Br₂ achieved the near-complete removal of bisphenol A (BPA) after 120 min through a synergistic process of adsorption and visible-light photocatalysis. The corresponding reaction rate constant for photocatalytic degradation approached 0.14 min⁻¹, which is significantly higher than those by Bi₄O₅Br₂ and ZnAl–LDH. Regarding the enhanced BPA removal over ZnAl–LDH/Bi₄O₅Br₂, the adsorption behavior occurred via hydrogen bonding and π-π stacking interactions, while the photocatalytic degradation involved the efficient photoexcitation and separation of charge carriers for the formation of reactive oxygen species (ROS) under the heterojunction effect. Electron spin resonance (ESR) and radical quenching experiments indicated that ROS including ·OH, ·O₂⁻, and ¹O₂, mainly contribute to BPA degradation. The predominant ROS formation mechanism was the interfacial reactions of the nanocomposite with H₂O molecules, as verified by the density of states, charge density differences, and adsorption energy calculations. Furthermore, the intermediate products of BPA degradation were identified, the degradation pathways were proposed, and the related ecotoxicity consequences were evaluated.
