Aluminum–silicon (Al–Si) alloys, due to their excellent heat storage density and thermal conductivity, are ideal candidates for high-temperature phase change materials (PCMs). However, metal-based PCMs are prone to leakage and corrosion during melting, which affects their stability. Traditional ceramic encapsulation suffers from poor thermal conductivity, a large mass ratio, and a lack of latent heat storage capacity, limiting its ability to meet the demands of efficient energy storage. This study proposes a novel design of a macro-capsule encapsulated with microencapsulated phase change materials (MEPCMs). By introducing MEPCMs into the outer shell of the macrocapsules, the system gains latent heat storage capability, increasing the mass content of the heat storage medium within the capsule and forming a dual heat storage unit of “core + shell”. Both the macrocapsules and the microcapsules are designed with thermal expansion cavities, effectively alleviating the volume expansion during the phase change process. The resulting macrocapsules exhibit a latent heat storage density of 420.9 J g−1 with an encapsulation efficiency of 86.8%. Within the operating temperature range of 500–700 °C, the maximum total thermal storage density reaches 630.7 J g−1. In addition, the thermal conductivity of the composite shell is 4.891 W m−1 K−1, representing a 217% increase compared with conventional ceramic encapsulation. After 100 thermal cycles, the latent heat retention remains as high as 99.2%, indicating that the developed macrocapsules have good potential for high-temperature thermal applications.

Rechargeable aluminum batteries suffer from dendritic anode growth and capacity decay due to severe concentration polarization caused by sluggish ion transport kinetics, particularly under high-capacity conditions. To address this issue, we developed an amorphous covalent organic framework (COF) coating layer engineered for anion-concentrating functionality. The conformational flexible imine linkages in the amorphous COF enable adaptive trapping of Al 2 Cl 7 − , storing them as crystalline AlCl 3 and ligand-bonded AlCl 4 − within the mesopores. This mechanism enriches electrochemical active species to buffer the concentration polarization, and promotes the formation of highly active Al 3 Cl 10 − species at the surface, thereby accelerating interfacial kinetics to guide homogeneous deposition. As a result, dendrite-free aluminum deposition is achieved even at an ultrahigh areal capacity of 10 mAh cm −2 under the protection of the COF. The half-cell with the COF exhibits an exceptional cycling time of over 6000 h with a coulombic efficiency of 99.9%, while symmetric cells demonstrate long-term stability over 7500 h with a low overpotential of 36 mV. Full cells with the graphite cathode also maintain stability over 5000 cycles under a large current density of 1.2 A g −1 . This work presents an effective coating strategy for regulating electrodeposition in metal anode batteries, highlighting a promising path toward practical applications.

The hierarchical porous architecture of sugarcane peel was successfully replicated using a biological template method. The samples were fabricated via a sol-gel process combined with ambient pressure drying, and the Si-Zr-Al-Y system integrated with the biomass template was pyrolyzed at temperatures ranging from 700 °C to 1300 °C to obtain Si-Zr-Al-Y oxide ceramic composites. The evolution of the microstructure and phase composition of the Si-Zr-Al-Y system during pyrolysis was systematically investigated. The incorporation of biomass templates facilitated the retention of a relatively fine mesoporous structure (6.88 nm) and low thermal conductivity (0.035 W·m⁻¹·K⁻¹) up to 1100 °C, although pore coarsening and specific surface area reduction became evident at higher temperatures (1300 °C). Furthermore, the influence of processing temperature on specific surface area, pore size, and pore structure was examined in detail. This study not only establishes a foundation for future research but also provides insights into sustainable industrial waste management and contributes to global sustainable development strategies.

In response to the prevailing challenges of the inherent trade-off between anti-icing performance and optical transparency, as well as poor environmental durability in anti-icing coatings, this study presents a multifunctional biomimetic coating that integrates efficient passive anti-icing capability, superior durability, and high optical transmittance. A UV-curable fluorinated polysiloxane/polyurea (FPSU) resin was synthesized, serving as the polymer matrix. Al₂O₃ microspheres were incorporated onto the surface via a spray-coating approach, with simultaneous resin crosslinking and robust anchoring of microstructures achieved through in situ UV curing, thereby enabling the successful fabrication of a biomimetic anti-icing coating of FPSUA imitating the surface of rose petals. The FPSUA coating achieves a static water contact angle of 158.22° and a sliding angle of 5.45°. On glass substrates, the freezing time increases from 25 s in the uncoated state to 618 s after FPSUA coating application, while the ice adhesion strength drops sharply from 357.96 kPa to 18.94 kPa. After rigorous exposure to sand impact, sandpaper abrasion, alcoholysis, and freeze-thaw cycles, the static contact angle remains above 150°, and the sliding angle stays below 11.49°. The FPSUA coating exhibits a refractive index of 1.432 and a transmittance of 80.32% at 589 nm. The FPSUA biomimetic anti-icing coating shows significant potential for anti−/de-icing applications in critical transparent components such as aircraft windshields, UAV sensor windows, and solar panels.

Al/Bi-O acid-base pairs were built by spatially selective Al doping in BiOBr/Bi 2 O 3 heterojunction. • The NH 3 yield reached 801.3 μmol g −1 h −1 in pure water, exceeding transition metal doped systems. • Al 3+ polarization activates lattice oxygen as primary Lewis base sites. • In situ KPFM visualizes S scheme charge transfer and the amplified built in field from Al doping. • Oxygen vacancies supply π backdonation channels and enrich electron density of nearby lattice oxygen. Photocatalytic nitrogen fixation has long been constrained by the intrinsic inertness of the N N bond and the severe recombination of photoexcited electron-hole pairs. Here, we construct an aluminum-doped BiOBr/Bi 2 O 3 S-scheme heterojunction in which Al 3 + selectively replaces Bi 3+ sites in the BiOBr lattice, while the Bi 2 O 3 phase retains its inherent crystal structure almost entirely. This asymmetric doping configuration strengthens the internal electric field across the S-scheme interface. The strong polarizing ability of Al 3+ activates nearby lattice oxygen atoms into Lewis base sites and induces the formation of additional oxygen vacancies (Ov), while simultaneously extracting electron density from adjacent Bi centers via Al-O-Bi bridge bonds, thereby enhancing the Lewis acidity of Bi. The resulting Al/Bi-O Lewis acid-base pair activates N 2 through a synergistic push-pull mechanism, in conjunction with the charge modulation induced by the oxygen vacancies. In pure water and in the absence of any sacrificial agent, the optimally designed photocatalyst achieves an NH 3 production rate as high as 801.3 μmol g −1 h −1 under simulated sunlight, surpassing transition-metal-doped analogues. This work establishes a lattice-confined Lewis acid-base pair paradigm, opening a new avenue for designing high-efficiency nitrogen-fixing photocatalysts.

Al-doping induced lattice distortion and structural defects in the TiO 2 shell. • Fe 3 O 4 imparts magnetic recoverability to the TiO 2 -Al photocatalyst. • 77.8% phosphorus mineralization of TnBP was achieved under UV irradiation. • DFT calculations reveal the engineered electronic structure boosts radical kinetics. • Photocatalytic treatment progressively reduced the biological inhibitory effect. Tributyl phosphate, a representative organophosphorus ester, is environmentally persistent due to its refractory nature, leading to widespread concern over its residue. Photocatalysis employing titanium dioxide (TiO 2 ) is a commonly studied method for degrading such pollutants, yet conventional TiO 2 systems are hindered by the high cost of requisite precious-metal cocatalysts, difficulties in recovering ultrafine catalyst powders, and rapid electron-hole recombination. To address these limitations, a TiO 2 -Al@Fe 3 O 4 photocatalyst was synthesized in this work via a sol-gel method, in which Al 3+ was doped into the TiO 2 lattice. This Al 3+ incorporation induced lattice distortion and created structural defects. The substitution of Ti 4+ by Al 3+ introduces charge imbalances and localized strain, which are key to forming active defect sites that subsequently modify the electronic structure. The modified catalyst exhibits a narrowed bandgap and an engineered surface structure that collectively further promote the generation of reactive oxygen species. Consequently, the TiO 2 -Al@Fe 3 O 4 /UV process achieved 77.8% phosphorus mineralization of tributyl phosphate within 10 h using a low photocatalyst dosage of 0.3 g/L. Furthermore, toxicity analysis indicated that most of the transformed products have lower predicted toxicity than the original parent compound. These results demonstrate that the TiO 2 -Al@Fe 3 O 4 composite functions as a magnetically recoverable and active photocatalyst, providing an effective strategy for the phosphorus mineralization of recalcitrant organophosphorus compounds.

Citrus leaf extract achieves 93.03% hydrogen evolution inhibition efficiency. • Significantly reduces hydrogen explosion risk from environmental fluctuations. • Phenol and (R)-3-pyrrolidinol are the active molecules of Citrus leaf extract. • Active molecules adsorb nearly parallel on Al (1,1,1). • O/N lone pairs donate to Al empty orbitals, forming coordination bonds. This study uses Citrus leaf extract (CLE), to validate inhibitor stability by simulating the internal environment of a wet scrubber, providing an intrinsically safe technology for industrial sites. Hydrogen inhibition experiments showed that the optimal CLE concentration for suppressing hydrogen generation was 4 × 10 −2 wt%, with an inhibition efficiency (η) of 93.03%. Under various environmental interferences, CLE at this concentration maintained stable inhibition performance. Characterization experiments indicated that CLE spontaneously adsorbs onto aluminum alloy dust surfaces, forming protective adsorption layers that prevent hydrolysis and hydrogen generation. DFT calculations revealed that the active molecules donated lone-pair electrons from O and N atoms in polar functional groups to the empty orbitals of Al to form coordination bonds, complementing the hydrogen inhibition mechanism. This study demonstrates that CLE, as a green and economical plant-based inhibitor, can ensure safe operation of wet scrubbers in industrial settings.

Graphical Synergistic catalysis ignition and combustion reaction mechanism of nanothermite Al/Bi2O3 with DAP-4 as additives. Aluminium/bismuth trioxide (Al/Bi 2 O 3 ), as a class of important and interesting nanothermite, had received much attention in the field of energetic materials. However, enhancing the ignition and combustion performance of Al/Bi 2 O 3 is still a great challenge. In this work, energetic perovskite DAP-4 was used to design and fabricate the ternary composites Al/Bi 2 O 3 /DAP-4 with the different contents of DAP-4 additives. The micromorphology and structure of composites Al/Bi 2 O 3 /DAP-4 were characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD). The ignition and combustion performances of composites Al/Bi 2 O 3 /DAP-4 were studied by electric heating ignition apparatus. The results showed that energetic perovskite DAP-4 was introduced to reduce the ignition energy of Al/Bi 2 O 3 and promote the combustion reaction of Al metal particles. With 10wt% DAP-4 added, Al/Bi 2 O 3 /DAP-4 sample showed a more durable combustion process for ∼270 ms. And with the contents of DAP-4 increased, the combustion time shortened and the burning intensity had improved. The intensity of flame combustion reaches the maximum when 30wt% DAP-4 is added. The main thermal decomposition gas products of Al/Bi 2 O 3 /DAP-4 composite are CO 2 , HCl, H 2 O, and so on. A synergistic catalysis ignition and combustion reaction mechanism of Al/Bi 2 O 3 with DAP-4 as additives was proposed. DAP-4 ignited by lower ignition energy could trigger nanothermite Al/Bi 2 O 3 . Bi 2 O 3 particles can reduce the thermal decomposition temperature of DAP-4, which accelerated the combustion reaction of nanothermite Al/Bi 2 O 3 with DAP-4 as additives. This work offered a new idea for design and application of nanothermite with high-performance catalysis additives.

Currently, the availability of defluoridativel materials to simultaneously achieve the high adsorption capacity and selectivity in complex aquatic environments remains limited. To this end, we constructed an aluminum-carbon composite (Al@C) with a near-network/highly interconnected microporous structure via carbonizating Al-based metal–organic frameworks (Al-MOF), for the selective and efficient elimination of F − in water environment. Results indicated that Al@C composite exhibited higher F − adsorption capacity (985.1 mg·g −1 ), outperforming the most reported adsorbents. Notably, Al@C maintained high selectivity for F − adsorption (97.8 %) even in the presence of high concentration of competing ions (SO 4 2− , CO 3 2– , HCO 3 – , Cl − , PO 4 3− , and NO 3 – ) and wide pH range (3–10). The superior adsorption capacity and selectivity were primarily attributed to the dual-ligand exchange mechanism, involving ligand exchange between F − and lattice oxygen to form Al-F bonds, and interaction between F − and carbon-based functional groups generating F-C-F/C-F bonds. Additionally, the heterogeneous diffusion process driven by surface adsorption and transition from carbon bond energies to higher binding energies induced by carbonization strategy, collectively strengthen the immobilization of F − . Overall, the work further provides an innovation, green, and low-energy solution for F − removal in environmental water treatment.

To address the critical limitations of natural bentonite, including restricted specific surface area and low cation exchange capacity (CEC) caused by interlayer impurities, this study proposes an in situ structural reconstruction strategy via simultaneous alkaline activation and aluminum doping. This approach directly transforms bentonite frameworks into a hierarchically porous SOD-type sodalite with an ultralow Si/Al ratio. The engineered material integrates three synergistic advantages: abundant surface hydroxyl groups, maximized CEC (saturation capacity, 242.56 mg/g), and a dual-scale pore architecture (micropores/mesopores). Combined experimental and computational analyses reveal the underlying mechanisms: The ultralow Si/Al ratio generates Al–O–Si bridging sites, strengthening electrostatic interactions with Pb2+ (adsorption energy: −1.356 eV) and reducing the migration energy barrier. Local charge redistribution at Al-rich domains optimizes Pb2+ occupation, achieving a stable Pb–O bond length of 2.35 Å. Hierarchical porosity facilitates rapid mass transfer, enabling 93% adsorption capacity retention after eight regeneration cycles. This work establishes a quantitative structure–performance relationship among Si/Al ratio, charge distribution, and adsorption efficiency through bentonite interlayer reconstruction. It provides fundamental insights for designing high-performance, low-cost heavy metal adsorbents, demonstrating a 2.7-fold increase in Pb2+ uptake compared to conventional bentonite, developing high-performance, low-cost heavy metal adsorbents.

Depolymerizing technical lignin into aromatic monomers is a promising route to renewable aromatic precursors for sustainable aviation fuels, yet it is hindered by the low reactivity of condensed C O and C C linkages. In this work, Al-modified silica nanosphere supported Ni catalysts (Ni/Al-SiO 2 ) are developed for selective lignin hydrogenolysis. The optimal Ni/Al 2 -SiO 2 achieves complete β-O-4 bond conversion and fully transforms 2-phenoxy-1-phenylethanol into phenol and ethylbenzene with yields exceeding 99%. In contrast, commercial Ru/C mainly produces ring-saturated products. Ni/Al 2 -SiO 2 also accelerates the hydrogenolysis of the β-1 bond in 1,2-diphenylethane, delivering high aromatic selectivity with no detectable cycloalkanes. For technical lignin, Ni/Al 2 -SiO 2 affords a 23% aromatic-monomer yield, outperforming that of Ru/C (19%), and maintaining consistent performance across various types of technical lignin. The incorporation of Al generates Lewis-acid sites and polar oxygen motifs, which enrich and polarize the substrates. Adjacent Ni 0 sites dissociate H 2 to generate reactive hydrogen, while strengthened interfacial adsorption, reduced key barriers, and promoted hydrogen spillover enable rapid hydrogenative capping of reactive intermediates, suppressing condensation and preserving aromatic selectivity. This work provides a non-noble-metal interface-engineering strategy for reductive depolymerization of technical lignin into aromatic-rich sustainable aviation fuel precursors.

Conventional biodiesel production relies on external heating, requiring high temperatures and strict control over system water content. This work prepared a magnetic lignin-based heterogeneous acid catalyst Fe 3 O 4 -LS/100-Al using sodium lignosulfonate as support via co-precipitation and impregnation, with Lewis acid sites, and applied it in electrolysis-assisted esterification for biodiesel. The catalyst showed a specific surface area of 115.63 m 2 /g and saturation magnetization of 29.98 emu/g, enabling efficient acid loading and rapid magnetic separation. Under RSM-optimized conditions (catalyst of 6.8 wt%, MOAMR of 12.5:1, voltage of 45.4 V, water content of 4.7 wt%), oleic acid conversion reached 95.25%. Low activation energy (36.04 kJ/mol) confirmed high catalytic activity, and 71.38% conversion was retained after seven cycles. Results prove electrolysis assistance enables efficient, ambient-temperature biodiesel synthesis.
