Summary: A strategy for enhancing the oxygen evolution reaction (OER) catalytic activity of NiFe layered double hydroxide (LDH) by incorporating CoTe nanosheets (NSs) is reported. The hybrid material (CoTe NS/NiFe LDH) exhibits a hierarchical 2D-2D heterostructure with an intact interface between the CoTe NS and NiFe LDH. The presence of CoTe NS on the NiFe LDH enhances charge transfer and reaction kinetics during the OER process, leading to lower overpotentials and excellent stability, outperforming the benchmark RuO2 catalyst.

Summary: Two-dimensional clay materials exhibit excellent thermal and chemical stability, and their atomic structures with tubular channels provide potential pathways for proton penetration. This study explores and investigates the mechanism of proton penetration across 2D clay nanosheets with various isomorphic substitutions and counterions using molecular dynamics simulations. The presence of negative surface charges significantly reduces the energy barrier for proton penetration, making it a promising choice for high-temperature proton exchange membranes. Additionally, the proton conductivity of single-layer clay materials can be tuned by altering the isomorphic substitutions.

Summary: The controllable adjustment of layered double hydroxide layer spacing has enabled its use as an electrode material for energy storage and electrochemical hydrogen evolution. However, lower conductivity and agglomeration have limited its large-scale application. In this study, sodium dodecyl sulfate (SDS) intercalation modification was used to construct LDH derivatives with vertically grown CoNi-SDS-LDH nanosheets on a nickel foam surface, resulting in a layered structure supported by nanowires which improved ion transport efficiency and reduced agglomeration. The electrode material demonstrated good electrochemical performance, with a cycling stability of 91% after 10,000 cycles and 98.1% performance retention after 10 hours of hydrogen evolution test. This anionic modification offers the potential for large-scale applications of LDH in flexible supercapacitors and electrocatalytic hydrogen evolution.

Summary: Ni-Co LDHs were synthesized with different Ni/Co molar ratios and used as cathode materials for Ni-MH batteries. Compared with Ni(OH)2, Ni-Co LDHs electrodes exhibited higher discharge capacity and cycling stability. The NC 2 electrode with a Ni/Co molar ratio of 4:1 showed the highest discharge capacity and capacity retention after 200 cycles. The unique morphology and enlarged interlayer spacing of Ni-Co LDHs promoted ion transmission and charge transfer, while their structural stability and synergies with Co-Co LDHs were important for electrochemical performances.

Summary: This paper synthesized diatomite-like potassium iron disulfide (KFeS2) using a multistep sacrificial template method, and investigated its morphological, electrochemical, and oxygen evolution reaction (OER) properties. It was found that KFeS2 had a porous, hollow, and cake-like structure, with a high specific surface area (SSA) and abundant electrochemically active sites. The unique structure and high porosity of KFeS2 resulted in a very high specific capacitance of 651 F g(-1). Additionally, diatomite-like KFeS2 showed a very low overpotential and a small Tafel slope, indicating its broad application prospects for energy storage and conversion.

Summary: In this study, core-shell heterostructured nanocomposites (Fe NWs@SiO2) were successfully prepared, consisting of ferromagnetic nanowires (Fe NWs) as the core and silica (SiO2) as the shell. These composites exhibited enhanced electromagnetic wave absorption and oxidation resistance and were synthesized using a simple liquid-phase hydrolysis reaction. The microwave absorption properties of Fe NWs@SiO2 composites with different filling rates were tested and analyzed, with the sample filled with 50 wt% showing the best comprehensive performance. At a matching thickness of 7.25 mm, the minimum reflection loss (RLmin) could reach -54.88 dB at 13.52 GHz and the effective absorption bandwidth (EAB, RL < -10 dB) could reach 2.88 GHz in the range of 8.96-17.12 GHz. The enhanced microwave absorption performance of the core-shell structured Fe NWs@SiO2 composites could be attributed to the magnetic loss of the composite, the core-shell heterogeneous interface polarization effect, and the small-scale effect induced by the one-dimensional structure. Theoretically, this research provided Fe NWs@SiO2 composites with highly absorbent and antioxidant core-shell structures for future practical applications.

Summary: One-dimensional iron-nickel heterogeneous nanowires with superior electromagnetic wave absorption were prepared using a magnetic-field-assisted liquid-phase reduction method. The electromagnetic properties of the absorber were controlled by changing the atomic molar ratio of Fe to Ni, with the composition of Fe:Ni atomic molar ratio of 1:1.5 exhibiting the best absorption characteristics. The absorber showed a minimum reflection loss of 26.106 dB at 18 GHz with a matched thickness of 2.175 mm and an effective absorption bandwidth of 6.08 GHz at 2.6 mm with a filler content of 25%. The successful exploration of this one-dimensional heterogeneous structure provides important insights for the future fabrication of absorbers with excellent electromagnetic wave absorption capability.

Summary: This study prepared a series of MOF-based derivatives using suitable methods and evaluated their electrochemical performance. It was found that phosphating treatment can enhance the material's electrical conductivity, while the layered structure facilitates the intercalation/deintercalation of electrolyte ions, and oxidation inhibits the release of electrochemical performance. Therefore, the enhancement effect in terms of electrochemical performance is ranked as follows: phosphorization > layer structure > oxidation. This study provides reliable criteria for the design and screening of advanced electrode materials.
