Graphical A series of Fe 2 O 3 ─CeO 2 ─C 3 N 4 (Fe–Ce–CN) catalysts were synthesized by a KCl–LiCl molten salt method. The 0.5 wt.% Fe 2 O 3 loaded Fe–Ce–CN which synthesized at 550 °C for 4 h had an excellent photocatalytic activity towards to tetracycline (TC) degradation due to the significantly boosted separation efficiency of photoexcited electron-hole pairs. In this work, Fe 2 O 3 ─CeO 2 ─C 3 N 4 (Fe–Ce–CN) catalysts were synthesized in the KCl–LiCl molten salt system, and their photocatalytic properties towards tetracycline (TC) degradation in wastewater were studied. The obtained 0.5 wt.% Fe–Ce–CN, synthesized at 550 °C for 4 h with 0.5 wt.% Fe 2 O 3 , had the highest photocatalytic degradation efficiency for tetracycline (TC), which achieved degradation ratios of 98.3% and 96.9% for TC solutions at concentrations of 20 mg/L and 80 mg/L, respectively. Characterizations indicated that the 0.5 wt.% Fe–Ce–CN had significantly enhanced photo-excited electron-hole separation efficiency and promoted photocatalytic activity. Additionally, superoxide radicals · O 2 − and electrons ( e − ) were identified as the key reactive species for TC degradation with 0.5 wt.% Fe–Ce–CN, attributing to its band structure. The possible enhancement mechanism was discussed and proposed. The findings in this work provide a new approach to preparing high-performance photocatalysts and offer insights into the Fe–Ce–CN ternary photocatalysts.

Graphical A method of in-situ fabrication is proposed to create a LiCl-rich artificial SEI on lithium metal anodes by reacting MoCl 5 with Li. This resulting interlayer enhances uniform lithium deposition, suppresses dendrite formation, and significantly improves the cycling stability and performance of lithium metal batteries, demonstrating potential for practical high-energy-density applications. In the pursuit of high-energy-density lithium metal batteries (LMBs), the development of stable solid electrolyte interphase (SEI) is critical to address issues such as lithium dendrite growth and low Coulombic efficiency. Herein, we propose a facile strategy for the in-situ fabrication of a LiCl-rich artificial SEI layer on Li surfaces through reaction of MoCl 5 with Li (Li@MoCl 5 ). The resulting artificial SEI significantly enhances the uniformity of Li deposition, effectively suppresses dendrite formation, and improves electrochemical performance. As a result, Li@MoCl 5 symmetric cells demonstrate remarkable stability, achieving continuous cycling of 4200 h under a high current density of 10 mA cm −2 with an areal capacity of 1 mAh cm −2 . Full-cells employing Li@MoCl 5 exhibit superior cycling stability and rate capability, even at high cathode loading (17 mg cm −2 ). These results highlight the potential of this interface engineering strategy for advanced practical application of LMBs.

Summary To recover Pr from molten chlorides, the electrode reactions of Pr 3+ on Sn-coated W and liquid Sn electrodes were studied by a group of electrochemical techniques. CV and SWV results exhibited that the electrochemical signals pertaining to the formation of Pr-Sn alloy compounds and solid solution appeared at less negative potentials than that of Pr 3+ on W electrode. The thermodynamic data of Pr-Sn alloy compounds and the kinetic parameters for PrSn 3 /Pr 3+ pair were determined employing OCP, LP, and Tafel methods, separately. The measured diffusion coefficient ( D ) of Pr in liquid Sn metal was 9.40 × 10 −6 cm 2 s −1 . Furthermore, the electrochemical recovering Pr from molten salt was performed using liquid Sn as a working electrode, and the formed Pr-Sn samples characterized by XRD and SEM-EDS were composed of Sn and PrSn 3 phases.

For UO 2 -based spent fuel , it is usually electrochemically reduced and then refined in molten salt with respect to the so-called pyrochemical reprocessing approach. In this work, we report a new method with the assistance of NH 4 Cl to directly achieve convenient separation of UO 2 over La 2 O 3 in Ar atmosphere which does not require an electrochemical process . According to the results from both powder and pellet samples, the separation is achieved by dissolving La 2 O 3 into the LiCl–KCl molten salt with NH 4 Cl, whilst UO 2 cannot be dissolved and remains in solid form. It was found that the dissolution kinetics of La 2 O 3 in the powder sample was fast and its removal efficiency in the mixture of La 2 O 3 and UO 2 was high, but a specific amount of UO 2 was also dissolved, which lead to a low recovery efficiency of UO 2 . In contrast, when the pellet samples after sintering at 1473 K were used, the recovery efficiency of UO 2 can be increased. Nevertheless, the dissolution kinetics of La 2 O 3 was correspondingly reduced, and more NH 4 Cl was required to complete the dissolution reaction . By improving and optimizing the experimental conditions, the UO 2 recovery efficiency of 92.0% can be achieved, while the removal efficiency of La 2 O 3 was 94.4%. More importantly, this novel separation method may be also useful for the separation of UO 2 over mixed lanthanide oxides.

The urgent need for high-energy–density rechargeable batteries is driving lithium (Li) metal as a promising anode material. However, the conventional solid electrolyte interface (SEI) on lithium metal suffers from elevated interfacial impedance, poor mechanical properties, and non-uniform Li + flux. Previously, LiF has been proven to be an effective component of the SEI protecting lithium metal. However, this is a rarely reported application of LiCl and LiBr in SEI. Herein, we design SEI containing lithium halide in different ratios (LiF 0.8 Cl 0.1 Br 0.1 , LiF 0.33 Cl 0.33 Br 0.33 , LiCl, LiBr) to investigate the action laws of lithium halide in SEI. It has been shown that the performance of SEI containing lithium halide against lithium anode increases with the LiF content in the SEI. The higher the proportion of LiF in SEI, the better the cycle life and stability of Li-Li symmetric cells, and the higher the initial capacity and the capacity retention of LFP-Li full cells. The symmetric cell with LiF 0.8 Cl 0.1 Br 0.1 @Li has the smallest average polarization voltage (about ± 30 mV) and long cycle life of up to 1000 h. LiFePO 4 ||LiF 0.8 Cl 0.1 Br 0.1 @Li cells have the highest initial capacity (127.4 mAh/g), and still had 83.6 % capacity retention after 1000 cycles at 2C.

Li metal anodes as one of promising anodes in next-generation batteries , face the challenges from infinite volume change and high reactivity to electrolytes that easily leads to unstable Li/electrolyte interface and unique dendrite growth of Li. Although mechanical pressure can effectively inhibit the dendrite growth of Li, it also increases the risk of short circuits, because Li metal easily grows into the separator under pressure. Here, an interface layer is introduced on Li metal to block this growth, using Li 3 P/LiCl as a model. Meanwhile, the dense and robust layer also reduce the side reactions between Li and electrolytes. With the helps from mechanical pressure and interface layer , this design exhibits the improved electrochemical performances, much better than that without pressure or without the layer. The full cells of Li 3 P/LiCl-coated Li//LiFePO 4 , show a capacity of 1.69 mAh cm −2 after 1000 cycles under pressure at 3.9 mA cm −2 with a capacity retention of 99.5% in carbonates. The results indicate the promising potential for the pressure effect to be used for advanced Li metal anodes .

The development of next-generation desiccant materials is essential for achieving energy-efficient atmospheric water harvesting and air dehumidification under hot and humid conditions. Conventional desiccants such as silica gel and zeolites are limited by high regeneration temperatures, low water uptake, or poor hydrothermal stability, while salt-based sorbents suffer from deliquescence and leakage. To address these challenges, this study presents a LiCl@TpPa-1 covalent organic framework (COF) composite that integrates the structural robustness of TpPa-1 with the hygroscopic functionality of lithium chloride. Structural and thermodynamic analyses confirmed that LiCl incorporation enhances water affinity without compromising crystallinity or stability, enabling low-temperature regeneration below 70 °C. The composite was successfully coated onto aluminum heat exchanger fins using an optimized polymeric binder, yielding a uniform, durable sorption layer. System-level testing demonstrated a more than threefold improvement in moisture removal and a 2.5-fold increase in thermal coefficient of performance (COP) compared to silica gel under tropical conditions. This study goes beyond material-level characterization by bridging the gap between laboratory synthesis and practical application. The composite was successfully coated onto aluminum heat exchanger fins using an optimized polymeric binder, forming a uniform and durable sorption layer. System-level testing under realistic operating conditions demonstrated more than a threefold enhancement in moisture removal and a 2.5-fold increase in the thermal COP compared to silica gel under tropical climates. The material also exhibited excellent cyclic stability with negligible capacity loss after repeated dehumidification–regeneration cycles. These results highlight LiCl@TpPa-1 as a promising desiccant for sustainable, low-grade heat-driven dehumidification and water-harvesting technologies.

Selective recovery of lithium from Salt Lake brines using environmentally friendly technologies is increasingly demanded to overcome the shortage of lithium. However, satisfying high separation precision is challenging for most polymer nanofiltration membranes. Besides, bestowing high permeance together with improved membrane fouling remains a challenge for the widespread implementation of membrane processes. Herein, a new tri-quaternary ammonium-based ionic liquid (TQAIL) electrolyte monomer is synthesized and utilized for the surface modification of nascent polyamide active layer to fabricate IL-modified polyamide nanofiltration (NF) membrane for Mg 2+ /Li + separation. Molecular dynamics simulations confirm that TQAIL modification creates nanoscale structural heterogeneity leading to enhanced surface hydrophilicity and reduces internal resistance through the membrane selective layer. The TQAIL membrane exhibits improved Li + /Mg 2+ selectivity and improved water permeability of 26.11 L m −2 h −1 bar −1 , which is fourfold that of unmodified membrane accompanied with a 100-h stable continuous nanofiltration. Moreover, the membrane displays good anti-biofouling behaviour with excellent antimicrobial properties. This study offers new insights into how surface functionalization using multication side chains can remarkably improve ion separations by molecularly tuning ion-membrane electrostatic interactions in polymeric membranes .

Ionically-conductive and stretchable hydrogels are ideally suited for the synthesis of flexible electronic devices. However, conventional hydrogels undergo dehydration at ambient conditions and freeze at subzero temperatures, limiting their functions. As an alternative to counteract these limitations, we propose double network hydrogels that are easily synthesized by a one-step acrylamide (AM) polymerization in the presence of cellulose nanofibrils (CNF) and LiCl. Following molecular dynamics simulation, thermogravimetric and spectroscopic (Raman and low-field nuclear magnetic resonance) analyses, we show that LiCl increases the interactions between the colloidal phase and water molecules, ensuring water holding capability at atmospheric conditions and endowing the hydrogels with freezing tolerance over a wide range of temperatures, from −80 to 25 °C. The synergy between CNF and LiCl is critical in maintaining the mechanical strength of the system, which simultaneously displays high stretchability (~748%) and ionic conductivity (2.25 S/m) at low temperatures (−40 °C). As a proof of concept, a flexible supercapacitor comprising the proposed electrolyte hydrogel is demonstrated as a reliable, low-temperature electrochemical device. Our results provide the basis for simple and universally applicable systems that fulfill the requirements of flexible electronics under extreme cold conditions.

The preparation of suitable SiC fiber (SiC f )/Al precursors is crucial for the fabrication of SiC f -strengthened Al alloys . In this work, a SiC f /Al precursor was prepared by pulse current deposition in a molten LiCl–KCl–AlCl 3 melt. The electrochemical deposition of Al 3+ was separately investigated on the Mo wire, Cu wire, SiC f , and Cu-coated SiC f electrodes. The intermediate Cu layer can eliminate the Li generated by the underpotential deposition on the carbon layer outside SiC f . In addition, open circuit chronopotentiometry was performed to confirm the reduction processes of Al 3+ on the Cu wire and Cu-coated SiC f , and the results indicate that Al 3+ exhibits similar reduction processes on the two electrodes. The deposited Al layer possibly formed Al–Cu alloys with the intermediate Cu layer on SiC f , which was beneficial to the connection between the Al layer and SiC f substrate. Scanning electron microscopy was employed to investigate the morphology and microstructure of the prepared SiC f /Al fiber. After the pulse current was optimized, a compact and even layer of Al was deposited on SiC f .

Urban heat islands and the rising energy consumption of dense cities call for scalable passive cooling solutions. Conventional green roofs offer ecological and thermal benefits but are constrained by the optical and physiological limits of natural leaves. Here, we report a bionic green roof material that replicates key leaf-inspired functions while enabling effective thermal regulation through engineered optical and hygroscopic properties. The material features a TiO 2 –LiCl/PVA composite film on a reflective aluminum substrate, combining high solar reflectance, strong sky-facing emissivity, and low downward thermal emission for efficient radiative cooling. The LiCl-doped PVA film is capable of reversible moisture absorption–desorption, emulating transpiration-driven evaporative cooling without irrigation or stomatal limitation. Outdoor experiments confirm significant reductions in roof and indoor temperatures under both sunny and cloudy conditions, while simulations predict 12.7%–23.1% reductions in annual cooling energy consumption in typical hot urban climates. The bionic green roof also exhibits excellent durability and self-cleaning capability, demonstrating a robust, maintenance-free approach for climate-adaptive and energy-efficient architecture. These results highlight a scalable material-based strategy that addresses key limitations of traditional vegetated roofs by integrating radiative and evaporative cooling, offering a practical route toward low-carbon and climate-adaptive architecture.
