However, the inherently sluggish reaction kinetics of metal fluorides result in unsatisfactory electrochemical performance. In this study, CoF₂ was combined with carbonaceous materials to obtain graphitic carbon-encapsulated CoF₂ nanoparticles uniformly embedded in an interconnected N-doped carbon matrix (CoF₂@NC), significantly boosting the inert kinetics and electronic conductivity. The CoF₂@NC nanocomposites exhibited a notable reversible capacity of 352.0 mAh·g⁻¹ at 0.2 A·g⁻¹. Notably, it maintained superior long-term cycling stability even at a high current density of 2 A·g⁻¹, with a capacity of 235.5 mAh·g⁻¹ after 1200 cycles, evidently exceeding that of commercially available CoF₂ electrodes. Kinetic analysis indicated that the enhanced electrochemical performance originated from the increased contribution of capacitive effects. Furthermore, in-situ electrochemical impedance spectroscopy (EIS) results verify that the improved cycling performance is associated with the enhanced interfacial stability of CoF₂@NC. This research not only proposes a solution for the challenges of conversion cathodes in lithium-ion batteries, but also offers novel synthesis strategies for designing high-energy metal fluoride materials.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"44 3","pages":"1594 - 1604"},"PeriodicalIF":9.6,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, safe and efficient hydrogen storage remains a significant challenge due to its inherent leakiness and flammability. To overcome these challenges, alloys featuring body-centered cubic (BCC) structures have emerged as compelling candidates for hydrogen storage, owing to their exceptional capacity to achieve high-density hydrogen storage up to 3.8 wt% at ambient temperatures. Nonetheless, their practical application faces limited dehydriding capacity, complex activation processes, high costs and poor cyclic stability. Various modification strategies have been explored to overcome these limitations, including lattice regulation, element substitution, rare earth doping and heat treatment. This progress report presents an overview of the previous advancements to enhance five crucial aspects (high-V, medium-V, low-V, V-free and high-entropy alloys) in composition design and hydrogen storage properties within BCC-structured alloys. Subsequently, an in-depth analysis is conducted to examine the relationship between crystal structures and hydrogen storage properties specific to BCC-structured alloys, covering aspects such as composition, crystal structure, hydrogen storage capacity, enthalpy and entropy. Furthermore, this review explores current challenges in this field and outlines directions for future research. These insights provide valuable guidance for the design of innovative and cost-effective hydrogen storage alloys.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":749,"journal":{"name":"Rare Metals","volume":"44 3","pages":"1497 - 1521"},"PeriodicalIF":9.6,"publicationDate":"2024-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, the detailed analysis of the adiabatic shear band microstructure evolution of a dual-phase 90W-Ni–Fe alloy under a high strain rate was conducted by combining advanced electron microscopic characterization, while discussing shear fracture from a mechanical perspective under thermoplastic instability. The high temperature and high stress environment inside the adiabatic shear band led to the refinement of the W phase and γ-(Ni, Fe) phase grains to the submicron level, and induced the elements redistribution of W, Ni, and Fe to precipitate W nanocrystalline with hardness as high as 11.7 GPa along the recrystallization grain boundaries of the γ-(Ni, Fe) phase. Mechanical incompatibility caused by the hardness difference between W nanocrystalline and γ-(Ni, Fe) phases led to a strain gradient at the interface.

Herein, a novel cerium-doped NiMo phosphate (labeled as Ce-NiMo(PO₄)_0.66) is designed and fabricated via a facile hydrothermal and phosphatization method. A comprehensive characterization reveals that the introduction of the rare metal element cerium with an enriched 4f electronic distribution near the Fermi level modulates the hybridization of the 3d-2p orbitals and optimizes the electronic structure of the NiMo-based phosphate catalysts, which leads to the synergy between the nickel–molybdenum dual sites and the phosphate active unit to synchronously enhance the water dissociation and proton dehydrogenation transfer of the HER process. Consequently, Ce-NiMo(PO₄)_0.66 exhibits excellent alkaline HER performance with overpotentials at 10 and 500 mA·cm⁻² current densities being only 40 and 295 mV, respectively, and desirable long-term durability at industrial current densities of 500 mA·cm⁻². An overall hydrazine splitting (OHzS) constructed with Ce-NiMo(PO₄)_0.66 as a hydrazine oxidation reaction (HzOR) and HER bifunctional electrocatalyst has been constructed to achieve industrial current densities at the low voltage of 0.92 V, verifying its practical feasibility for sustainable hydrogen production and degradation of hydrazine pollutants.

This work proposed a one-step thermal copolymerization to obtain Cu (I) doping porous carbon nitride (CUCN) through a spontaneously reducing atmosphere by urea in a covered crucible. The obtained CUCN had crumpled ultrathin nanosheets and mesoporous structures, which possessed higher specific surface areas than PCN. From X-ray absorption near edge structure (XANES) and Fourier transform extended X-ray absorption fine structure (FT-EXAFS) spectra analysis, the Cu doping existed in the oxidation state of Cu (I) as single atoms anchored on the 2D layers of CN through two N neighbors, thereby facilitating efficient pathways for the transfer of photoexcited charge carriers. Furthermore, the photoluminescence (PL) spectra, electrochemical impedance spectra (EIS) and transient photocurrent response test proved the improved separation and transfer of photoexcited charge carriers for Cu (I) introduction. Consequently, the photocatalytic activity of CUCN was much better than that of PCN for antibiotics norfloxacin (NOR), with 4.7-fold higher degradation reaction rate constants. From species-trapping experiments and density function theory (DFT) calculations, the Cu single atoms in Cu–N₂ served as catalytic sites that could accelerate charge transfer and facilitate the adsorption of molecular oxygen to produce active species. The stable Cu (I) embedded in the layer structure led to the excellent recycling test and remained stable after four runs of degradation and even thermal regenerated treatment. The degradation paths of NOR by CUCN under visible light were also demonstrated.
