Aluminum batteries have received extensive research because of the safety, abundance and high capacity of Al anode. Most previous works are concentrated on improving the specific capacity of the cathodes, while other important issues such as cheap cathode-electrolyte system and high areal active material loading have often been overlooked. This paper reports that cheap graphite paper (GP) coupled with low price AlCl 3 /Et 3 NHCl ionic liquid (IL) electrolyte can form a practical Al dual-ion battery (ADIB). By adjusting the AlCl 3 content in IL, the energy storage of GP with high-loading is improved. The ADIB exhibits 71 mAh g −1 at 200 mA g −1 with a loading of 15.16 mg cm −2 , which is almost unattenuated over 1400 cycles. The GP cathode presents 47 mAh g −1 at 150 mA g −1 when the loading increased to 30.21 mg cm −2 . Even at an ultrahigh loading of 46.35 mg cm −2 , the cathode can still achieve 75 mAh g −1 (3.5 mAh cm −2 ) at 40 mA g −1 for over 500 stable cycles. The high capacity is contributed by a self-activating process of AlCl 4 − intercalation, which is closer to the diffusion-controlled battery behavior. The GPs simultaneously exhibit high areal capacity, energy/power density and long-life cycling performance which demonstrates their wide commercial prospects.

An electrochemical method was developed for the formation of Al-Cu alloys. The electrodeposition of aluminum on Mo and Cu substrates was studied using cyclic voltammetry in molten LiCl-KCl-AlCl 3 (2 wt.%). During the cathodic scan of the cyclic voltammograms, three different Al-Cu alloys were observed before pure Al formed on the Cu substrate. The electrochemical formation processes were studied using square wave voltammetry and open circuit chronopotentiometry. The products of the different reduction processes were identified using XRD. The XRD results indicated that three different Al-Cu intermetallic compounds, Al 4 Cu 9 , AlCu, and Al 2 Cu, were obtained using electrochemical deposition in the molten salt system.

Nonaqueous rechargeable Al batteries (RABs) have attracted significant research interest due to the extremely abundant reserves, high theoretical capacities, and low-cost. However, the commonly used nonaqueous RAB ionic liquid (IL) electrolytes are highly air-sensitive and high-cost, which seriously limits their commercial application. Herein, AlCl3–guanidine hydrochloride (AlCl3–GdnHCl), a new low-cost and environmentally friendly deep eutectic solvent (DES) with only 1/40 of the cost of [EMIm]AlxCly is introduced into applications for nonaqueous RABs. The battery displays a discharge capacity of 128 mAh g–1 at 0.1 A g–1, which is significantly higher than that of 88 mAh g–1 in [EMIC]AlxCly electrolyte. It can reach 124.6 mAh g–1 at 1 A g–1 with the Coulombic efficiency of 99.5% for 1000 cycles. According to the mechanism studies, during the charge–discharge cycle, the fast deposition/dissolution reaction of Al took place at the anode side, while intercalation/deintercalation reaction of [AlCl2(Gdn)n]+ ions and chloroaluminate anions [AlxCly]− (i.e., Al2Cl7– and AlCl4–) occurred at the graphite cathode side. With such significant electrochemical behaviors, the AlCl3–GdnHCl DES possesses great potential for use in high-performance storage devices.

Aluminum is toxic to both humans and animals. Exposure to AlCl 3 can lead to kidney function damage, yet the specific underlying mechanism remains elusive. This study aimed to investigate whether ferroptosis is involved in the renal toxicity induced by AlCl 3 exposure in mice and to elucidate its potential molecular mechanism. Forty-eight C57BL mice were randomly assigned to six groups, with eight mice in each group: a control group, low -, medium -, and high - dose aluminum exposure groups, a ferroptosis inhibitor group, and a ferroptosis inhibitor + high - dose aluminum exposure group. Mice in the aluminum exposure groups received intraperitoneal injections of different doses of AlCl 3 solution for 4 weeks (5 times per week), while the ferroptosis inhibitor group was intraperitoneally injected with Fer - 1 for 4 weeks (2 times per week). After the experimental period, multiple indicators were examined. The results demonstrated that AlCl 3 exposure impaired the renal function and structure of mice. It also led to an increase in lipid peroxidation products, Fe 2+ , and Al content in renal tissue. Moreover, the expression levels of genes and proteins such as GPX4 and Nrf2 were decreased, whereas the expression levels of the ACSL4 gene and protein were increased.However, after pretreatment with Fer - 1, the aforementioned indicators were ameliorated. Specifically, the expression of ACSL4 decreased, and the expression of GPX4 and other related factors increased.In conclusion, this study suggests that AlCl 3 exposure may trigger ferroptosis in renal tissue cells by inhibiting the NRF2 pathway, thereby causing kidney function damage in mice. These findings provide a novel perspective on the mechanism of AlCl 3 - induced renal toxicity.

The electrochemical behavior of Pr(III) and formation process of Pr-Al intermetallics were investigated by different electrochemical methods. The reduction of Pr(III) ion to metallic Pr is an one-step three-electrons reaction. The reversibility of Pr(III)/Pr(0) system was evaluated by cyclic voltammograms with different scan rates. The co-reduction of Pr(III) and Al(III) ions formed three different Pr-Al intermetallics at electrode potentials around −1.40, −1.80, and −1.95 V vs. Ag/AgCl at 723 K, respectively. Open-circuit chronopotentiometry and electromotive force (emf) measurements were carried out to estimate the relative molar Gibbs energies of Pr for the formation of different Pr-Al intermetallics in the temperature range of 723–843 K. The activities of Pr in the Pr-Al intermetallic compounds were calculated.

To further explore the application of the low-temperature molten salt in processing heavy rare earths, the properties of ytterbium in AlCl 3 -NaCl melts have been investigated. In this melt, YbCl 2 powder products are prepared by electrolysis based on the dissolution reaction of Yb metal. The properties of Yb(II) in AlCl 3 -NaCl melts have also been studied in detail. In-situ UV–VIS absorption spectroscopy demonstrates that the coordination of Yb(II) changes in AlCl 3 -NaCl melts with different Lewis acidity, leading to variations in its diffusion ability. In addition, the conversion of Yb(II)/Yb(III) shows typical soluble-soluble reversible electrochemical behavior in strongly acidic AlCl 3 -NaCl. However, the electrochemical behavior of Yb(II) on inert electrodes becomes complicated when the amount of AlCl 3 in AlCl 3 -NaCl melts less than 52 mol%. This change is attributed to the formation of a YbCl 3 passivation film on the inert electrode during the electro-oxidation of Yb(II). Soaking the passivated electrode in the melt can alleviate the passivation. Understanding the electrochemical and spectroscopic properties of ytterbium in AlCl 3 -NaCl melts paves the way for its subsequent applications.

NH 3 ·H 2 O can result in severe accidents when leaking in a confined space. In this work, a novel powder-water mist synergistic strategy for decontaminating NH 3 ·H 2 O in a confined space is proposed. Initially, FeCl 3 /AlCl 3 was employed to modify diatomite, decorating its pore structure and augmenting the number of acidic adsorption sites. The modified diatomite achieves a notable efficiency of 74.6%, surpassing that of the raw diatomite (43.8%). Subsequently, surfactants were introduced to increase the contact area between the water mist and NH 3 , while a thickening agent was employed to suppress the fluidity of NH 3 ·H 2 O. Ultimately, the powder-water mist synergistic decontamination system was constructed by integrating the diatomite with a thickening agent and water mist containing surfactants. The synergistic system exhibits a superior decontamination efficiency of approximately 80%. This work generates fresh insight into decontaminating NH 3 ·H 2 O in a confined space and offers a crucial avenue for future advancements in decontamination technology.

Membrane scaling severely hinders practical application of nanofiltration (NF) for brackish water treatment. However, the contributions of residual aluminum ( Al ), especially various species with differing polymerization degrees and sizes, to gypsum scaling remain unclear. Herein, the complex interactions between three Al species (AlCl 3 , Al 13 and Al 30 ) and gypsum scaling were investigated, including surface and bulk crystallization processes. Results demonstrated that Al species adhering to the membrane surface promoted surface crystallization and altered crystal morphology. Notably, the Al 13 species induced the formation of dense, complete rosette crystals causing the most severe flux decline. For bulk crystallization, Al 30 was the primary species to promote nucleation. This promotion resulted from two factors: a lower nucleation energy barrier and the promoted aggregation of small crystals. Furthermore, molecular dynamics (MD) simulations revealed that the inhibition of nucleation due to the competition between Al species and calcium ions at nucleation sites was negligible compared to the strong promotion effect. These findings demonstrated that PACl exhibit higher scaling potential during NF than monomeric Al coagulants. Ultimately, the competition between surface and bulk crystallization determined the final membrane flux decline. This study offers valuable insights into the mechanisms of NF scaling caused by residual Al and guides mitigation strategies.

Petroleum-based plastic packaging stays in the environment longer and raises safety concerns, prompting the development of sustainable bio‑based alternatives. Herein, high‑performance regenerated cellulose (RC) films reinforced with phenolated lignin nanoparticles (P‑LNPs) were developed by dissolving softwood pulp in an ZnCl 2 /AlCl 3 inorganic molten salt hydrate system and regenerating it in water. Phenolation increased lignin’s phenolic–OH content, and nanolization allowed for uniform nanoparticle dispersion and strong interfacial interactions within the cellulose matrix. At 3 wt% P‑LNPs (RCPL‑3), the composite film showed a balanced profile: tensile strength of 89.14 MPa; elongation at break of 9.47%; water vapor permeability of 0.91 × 10⁻¹ ² g·cm/(cm²·s·Pa); visible‑light transmittance of 83.78%; UV blocking over 90%; and a water contact angle of 103.2°. The films possess antioxidant activity and inhibit the growth of Escherichia coli and Staphylococcus aureus . In a model application, RCPL-3 effectively slowed banana peel browning and reduced 7-day weight loss to 18%. Soil burial tests confirmed biodegradability with 71% mass loss after 60 days. These findings show that P-LNPs work together with regenerated cellulose to produce transparent, barrier-improved, antioxidant, and antibacterial films suitable for active, biodegradable food packaging.

Aluminum storage systems with graphite cathode have been greatly promoting the development of state-of-the-art rechargeable aluminum batteries over the last five years; this is due to the ultra-stable cycling, high capacity, and good safety of the systems. This study discussed the change of electrochemical behaviors caused by the structural difference between flake graphite and expandable graphite, the effects of temperature on the electrochemical performance of graphite in low-cost AlCl 3 –NaCl inorganic molten salt, and the reaction mechanisms of aluminum complex ions in both graphite materials by scanning electron microscopy, X-ray diffraction, Raman spectroscopy, cyclic voltammetry, and galvanostatic charge–discharge measurements. It was found that flake graphite stacked with noticeably small and thin graphene nanosheets exhibited high capacity and fairly good rate capability. The battery could achieve a high capacity of ∼219 mA hg −1 over 1200 cycles at a high current density of 5 Ag −1 , with Coulombic efficiency of 94.1%. Moreover, the reaction mechanisms are clarified: For the flake graphite with small and thin graphene nanosheets and high mesopore structures, the reaction mechanism consisted of not only the intercalation of \({\rm{AlCl}}_4^ - \) anions between graphene layers but also the adsorption of \({\rm{AlCl}}_4^ - \) anions within mesopores; however, for the well-stacked and highly parallel layered large-size expandable graphite, the reaction mechanism mainly involved the intercalation of \({\rm{AlCl}}_4^ - \) anions.

Liquid coordination complexes (LCCs), which are formed between metal halides and donor molecules, represent promising catalysts. Six amide-AlCl3LCCs were successfully synthesized, followed by their characterization through NMR, Raman, and UV-visible spectroscopy. The acidity of these LCCs was quantified by performing computational modelling of fluoride ion affinities (FIA) and experimental Gutmann–Beckett measurements. Spectroscopic analysis indicated bidentate coordination between amide ligands and Al, which induced asymmetric splitting of Al2Cl6into diverse ions such as [AlCl2L2]+, [AlCl4]−, [AlCl3L], and [Al2Cl6L]. The computed FIA was found to align well with the experimental acidity trends, thereby confirming the proposed structure of the LCC. In the alkylation tests, the LCC with a high acidity demonstrated an increase in the yields of C5-C7alkylates. These results provide an in-depth understanding of the tuneable structures of amide-AlCl3LCCs. The acidity of LCCs can be controlled by tuning the ratio of the organic ligand to AlCl3, which allows bidentate coordination to facilitate asymmetric splitting of Al2Cl6. The LCCs demonstrate a high degree of potential as versatile and sustainable acid catalysts in alkylation reactions. These findings may advance the foundational knowledge of LCCs for the purpose of targeted acid catalyst design.Keywords:liquid coordination complexes;Lewis acidity;density functional theory;NMR;C4alkylation catalysts

The variable valence rare earth elements are difficult to separate due to their similar properties and intermediate valence states in molten salts. In order to realize their efficient and selectivity separation, the properties and separation methods of Sm, Yb, and Eu have been investigated in a low-temperature AlCl 3 -NaCl molten salt. It has been found that the oxidation reactions of different Ln(II) to Ln(III) have different potentials. The Ln(II)/Ln(III) reaction is also irreversible when the AlCl 3 content is less than 50 mol%, Ln(III) exists in the form of LnCl 3 precipitation. Therefore, selectively modulating the valence of Sm, Yb, and Eu by electrochemical methods can achieve their separation. The LnCl 3 produced from the Ln(II) electro-oxidation precipitates and separates from the other unoxidized soluble Ln(II) in AlCl 3 -NaCl melt. The efficient separation of Ln(II) in AlCl 3 -NaCl can be achieved by pulse potentiostatic electrolysis. Under these conditions, the separation factors of Sm-Eu, Sm-Yb, and Yb-Eu can reach 10 3 . The maximum removal of Ln(II) exceeded 99 % with a maximum current efficiency of more than 90 %. Most importantly, the separation of variable valence rare earth elements has been realized in a low-temperature AlCl 3 -NaCl melt.
