However, structural collapse, facile deactivation during desorption process, and ultra-low actual adsorption capacity limit its further large-scale application, particularly in low-grade sulfate-type brines. Herein, considering its advantages, limitations, and structural features, the structural collapse of the aluminum-based lithium adsorbent was effectively suppressed by the in situ intercalation of VO₃⁻ and V₂O₇⁴⁻ into the interlayer of [LiAl₂(OH)₆]⁺.

Based on experiments and density functional theory calculations, the process and mechanism of anion intercalation control were preliminarily elucidated. Furthermore, research findings indicate that intercalated anions can influence not only interlayer interactions but also the backbone strength of LDH-type adsorbents.

In this study, Cu and Ag bimetals were incorporated into covalent organic frameworks to fabricate thin-film nanocomposite membranes. The hydrophilic monomer 1,3,5-tris(4-aminophenyl) benzene of covalent organic frameworks was introduced as a water phase monomer during interfacial polymerization to enhance the organic–inorganic compatibility. The incorporated covalent organic frameworks within the thin-film nanocomposite membrane loosened the selective layer, resulting in an enhanced permeability of 24.6 LMH bar⁻¹. The membrane exhibited a rejection rate over 99.0% for Congo Red, Xylene Brilliant Cyanine G, and Reactive Blue, while exhibiting relatively low rejection rates of MgCl₂ and NaCl. Moreover, the outstanding catalytic capability of the incorporated bimetals led to a 4-nitrophenol conversion rate of 84.38%, enabling simultaneous conversion and separation. The integration of covalent organic frameworks and bimetals also imparted robust antibacterial properties, significantly enhancing operational stability.

However, synthesizing such precisely engineered architectures while maintaining atomic dispersion of distinct metal centers remains a formidable challenge due to thermodynamic instability and synthetic complexity. We herein propose a topological confinement pre-anchoring strategy via pre-anchoring spatially resolved Zn/Fe dual-metal sources in a structurally engineered metal–organic framework precursor to synthesize atomically dispersed ZnFe bimetallic single-atom catalysts. Extended X-ray absorption fine structure measurements and X-ray absorption near-edge structure reveal that the atomically dispersed Zn/Fe metal sites and electronic redistribution in ZnFe bimetallic single-atom catalysts. The ultrahigh surface area, hierarchical pore, and synergistic effect between Zn/Fe can greatly favor the exposure of the active site, mass transport, and improvement of intrinsic activity. Consequently, the ZnFe bimetallic single-atom catalyst demonstrates superior oxygen reduction reaction performance, achieving a half-wave potential of 0.86 V and delivering a kinetic current density of 10.1 mA cm⁻² at 0.85 V versus RHE in 0.1 <span>m</span> KOH electrolyte.

While light intensity exhibits minimal impact during storage, the spectral composition of illumination selectively enhances <i>V</i>oc comprising reversible and irreversible contributions. Structural characterization reveals that prolonged storage degrades the quality of perovskite crystals in the upper region of the perovskite layer, whereas light storage promotes the relaxation of microstrain at the buried interface with a p-type organic layer. This structural reorganization at the interface, accompanied by lattice expansion, accounts for suppressed nonradiative recombination and a corresponding increase in quasi-Fermi level splitting. Consequently, devices fabricated without chemical defect passivation achieve a power conversion efficiency of higher than 40% under indoor lighting conditions after preconditioned by continuous exposure to ambient light during storage.
