Article Abstract
In this work, the lamellar precursor PLS-1 was successfully modified by acid treatment, intercalation and interlayer silylation. The layered precursor PLS-1 with CDO topological structure was synthesized using H-magadiite as silicon source and tetramethylammonium hydroxide (TMAOH) as template agent. After acid treatment to remove interlayer organic molecules, various OSDA were introduced between the layers, and the interlayer expanded intercalated materials were obtained. Intercalation can not only improve the crystallization degree of the sample, but also introduce larger organic molecules between the layers to increase the interlayer distance. 1,3-Dichlorotetramethyldisiloxane was used to silanize the intercalated material. The silanization conditions were investigated and the best conditions were obtained. Through the construction of the theoretical model, the experimental data were compared to show that the new molecular sieve PLS-1-2Si material has a 12 × 12-R interlayer expanded structure.

The design of carbon allotropes that simultaneously exhibit mechanical robustness and quantum functionalities remains a longstanding challenge. Here, we report a comprehensive first-principles study of cT16, a three-dimensional sp-hybridized carbon network with topologically interlinked graphene-like sheets. The structure features high ideal tensile and shear strengths, with pronounced anisotropy arising from strain-induced bond rehybridization and interlayer slipping mechanisms.

Two-dimensional (2D) materials offer strong light-matter interaction and design flexibility beyond bulk semiconductors, but an intrinsic limit is the low absorption imposed by the atomic thickness. A long-sought-after goal is to achieve complementary absorption enhancement through energy transfer (ET) to break this limit. However, it is found challenging due to the competing charge transfer (CT) process and lack of resonance in exciton states.

The O3-type NaNiFeMnO material is modified by introducing Sr into the Na sites and Al into the transition metal (TM) sites. The inactive Sr and Al serve as structural pillars within the NaO and TMO slabs, respectively, expanding the interlayer spacing and boosting the stability of the structure. The optimized cathode demonstrates a good rate performance of 117.

Hard carbon is the most commercially viable anode material for sodium-ion batteries (SIBs), yet its application in ester-based electrolytes is hindered by sluggish interfacial ion diffusion and limited sodium nucleation kinetics. After comprehensive evaluation, an interfacial chemistry regulation strategy was proposed based on orbital hybridization between bismuth and electrolyte ions, which was realized through the introduction of ammonium bismuth citrate. The surface bismuth particles regulate the formation of a NaF-rich SEI through improved anion affinity.

NHVO (NVO) is considered a promising cathode material for aqueous zinc-ion batteries due to its high theoretical capacity. However, its practical application is limited by irreversible deamination, structural collapse, and sluggish reaction kinetics during cycling. Herein, K and CN co-intercalated NVO (KNVO-CN) nanosheets with expanded interlayer spacing are synthesized for the first time to achieve high-rate, stable, and wide-temperature cathodes.
