Catalytic transfer hydrodechlorination of plastic pyrolysis oil on supported transition-metal catalysts using isopropanol as a hydrogen donor was investigated in this work. The catalysts were characterized by N2 adsorption, X-ray diffraction, hydrogen temperature-programmed desorption, and X-ray photoelectron spectroscopy, and the reaction products were identified by GC-MS. Among various Al2O3-supported transition-metal (Cu, Co, Ni) catalysts, Cu/Al2O3 exhibited the best catalytic transfer hydrodechlorination performance due to the superior activation ability of Cu/Al2O3 for isopropanol. The doping of Ni in Cu/Al2O3 significantly enhanced its catalytic activity due to the inherent excellent hydrogenation activity of Ni, good metal dispersion, and strong Ni-Cu interaction in Ni-Cu/Al2O3. GC-MS results revealed that chlorobenzene was hydrogenated to benzene and HCl, and isopropanol was dehydrogenated to form acetone, which was subsequently transformed to methyl isobutyl ketone. The reactivities of three representative organochlorine compounds followed the order of chlorobenzene > tetrachloroethane > tetrachloroethylene. Ultradeep dechlorination of real plastic pyrolysis oil was achieved by catalytic transfer hydrodechlorination over the optimal 15Ni-10Cu/Al2O3 catalyst. The chlorine content of real plastic pyrolysis oil was reduced from 61.7 to 0.5 mg/L with a chlorine removal of 99.2% after reaction for 3 h at the reaction temperature of 210 °C. © 2025 American Chemical Society.

The recently emerged chloride solid electrolytes have garnered significant attention due to their superior ionic conductivity, wide electrochemical stability window, and exceptional compatibility with high-voltage oxide cathodes. Nevertheless, the currently cost-effective Zr-based chloride solid electrolytes face significant challenges, including low ionic conductivity and poor moisture stability. Herein, a versatile Zn2+-doped Zr-based chloride electrolyte is presented, designed to meet the aforementioned requirements. The optimized Li2.4Zr0.8Zn0.2Cl6 exhibits an improved ionic conductivity of 1.13 mS cm−1 at 30 °C. Simultaneously, the Li2.4Zr0.8Zn0.2Cl6 also demonstrates impressive moisture stability, maintaining its structural integrity after exposure to humid air. The mechanism underlying the enhanced moisture stability of Li2.4Zr0.8Zn0.2Cl6 is further elucidated by density functional theory calculations. Most notably, whether coupled with LiCoO2 or LiNi0.8Mn0.1Co0.1O2 cathodes, Li2.4Zr0.8Zn0.2Cl6-based all-solid-state batteries demonstrate exceptional cycling stability and rate performance. This high ionic conduction and moisture-resistant chloride electrolyte holds great promise for significantly advancing the commercialization of all-solid-state lithium batteries. © 2025 Wiley-VCH GmbH.

Large scale and ultra-thin conductive two-dimensional metal films (<3.5 nm) for fast flexible electronics

Pushing the thickness of two-dimensional (2D) metal films to below 10 nm means higher transparency and better flexibility, which will help improve the response sensitivity of flexible electronic devices based on 2D metals. However, lattice distortion and void cracks are facile occurred in the 2D metal film due to the island structure growth mechanism on the traditional solid substrates, which greatly weakens the transparency and conductivity of ultra-thin 2D metal films. Here, we innovatively proposed an air–liquid interface deposition (ALID) method to address this dilemma, in which ultrathin 2D metal films with continuous conductivity were deposited on liquid substrates. Thanks to the shallow injection and the Brownian motion of the liquid substrate, 2D metal (Au, Ag, Cu, Bi, Pt, etc.) films with dimensions up to φ 90 mm × 3.5 nm were obtained through the above method with continuous conductivity in only 5 s. More importantly, compared with the metal film prepared by traditional air–solid interface deposition method, the metal film prepared through ALID has lower surface roughness (0.207 nm), better transparency (85 %), and stronger wear resistance since metal atoms can be arranged almost freely on the isotropic liquid surface. Furthermore, the fabricated resistance sensor based on these 2D metal films can realize flexible sensing such as bending, hitting and stretching motions with ultrafast response time (t = 60 ms) and robust response sensitivity (R/R0 = 800 %). On the one hand, it provides a new solution for the large scale preparation of ultra-thin continuous conductive films, and on the other hand, it enriches the growth mechanism of thin films on the liquid surface. © 2025 Elsevier Ltd

Ti–Mn hydrogen storage alloys have excellent comprehensive advantages, including high reversible capacity, good cycling stability, and cost-effectiveness. However, the significant hydrogen absorption and desorption hysteresis hinders its practical applications. In this work, a systematic investigation is conducted into the effects of Cr content on the composition, structure, and hydrogen storage properties of Ti1.25Mn1.75-xCrx (x = 0, 0.05, 0.15, and 0.25) alloys, with a particular focus on the impact of Cr introduction on the hydrogen absorption and desorption hysteresis of these alloys. The experimental results indicate that the alloy exhibits the best overall hydrogen storage properties when x = 0.15, with a maximum reversible hydrogen storage capacity of 1.96 wt%. The introduction of Cr can significantly reduce hysteresis without notably altering the hydrogen absorption and desorption properties. The hysteresis factor decreases from 0.1881 (x = 0) to 0.0496 (x = 0.25). Notably, a reasonable explanation for how the introduction of Cr reduces hysteresis in Ti–Mn alloys based on the material's plastic deformation properties is given. This study provides insights for the design of Ti–Mn alloys with low hysteresis and high capacity. © 2025

Water electrolysis represents a promising pathway for hydrogen generation. However, its practical implementation is constrained by the kinetically sluggish anodic process of the oxygen evolution reaction (OER). Recently, a strategy of replacing OER with the sulfide oxidation reaction (SOR) has garnered significant attention. By coupling SOR with the cathodic hydrogen evolution reaction (HER), this approach reduces the overall reaction overpotential, facilitates the simultaneous purification of sulfide-containing wastewater, and recovers sulfur resources, thereby achieving dual benefits of environmental remediation and economic value. This Review initiates with a systematic elucidation of the SOR mechanistic framework and comprehensively catalogs recent advancements in bifunctional electrocatalysts for integrated SOR||HER systems, such as metal (hydr)oxides, metal sulfides, heterojunction catalysts, and alloy catalysts. In light of the relationship between active site modulation and catalyst structure, we suggest methods for improving the performance of SOR catalysts and outline future directions for SOR. © 2025 American Chemical Society.

Composite material hydrogen storage cylinders are the most effective solution for high-pressure gaseous hydrogen storage. The carbon fiber fully wrapped plastic liner cylinder (Type IV cylinder) is the most important potential in the development of hydrogen storage. Accurately predicting the burst pressure and failure mode of type IV cylinders is basement for the lightweight design of these cylinders. Current burst failure prediction methods are developed base on traditional laminated structural models, where the influence of fiber bundles cross undulation that occurs during the helical winding process are not considered. This paper comprehensively investigated the influence of fiber bundles cross undulation on the fiber strength by combining numerical and experimental approaches, and a failure prediction method which takes into account of the strength knock-down effect was developed for type IV cylinders. The burst pressures and failure locations of three different types of IV cylinders were predicted and compared with the ones that predicted by traditional method which does not consider the strength knock-down effect. The physical bursting experiments were conducted, and the results validate that the numerical analysis method considering the strength knock-down effect can give more accurate prediction of the failure location and reduce the prediction error of the bursting pressure, the maximum error is reduced from +15.42% to +6.07%. © 2025 Beijing University of Aeronautics and Astronautics (BUAA).
