Lithium metal batteries (LMBs) with high energy density have received widespread attention; however, there are usually issues with lithium dendrite growth and safety. Therefore, there is a demand for solid electrolytes with high mechanical strength, room-temperature ionic conductivity, and good interface performance. Herein, a 3D cross-linked metal-organic framework (MOF)-derived polymer solid electrolyte exhibits good mechanical and ionic conductive properties simultaneously, in which the MOF with optimized pore size and strong imidazole cation sites can restrict the migration of anions, resulting in a uniform Li flux and a high lithium-ion transference number (0.54). Moreover, the MOF-derived polymer solid electrolytes with the 3D cross-linked network can promote the rapid movement of Li and inhibit the growth of lithium dendrites. Lithium symmetric batteries assembled with the 3D MOF-derived polymer solid electrolytes are subjected to lithium plating/stripping and cycled over 2000 h at a current density of 0.1 mA cm and over 800 h at a current density of 0.2 mA cm. The Li/P-PETEA-MOF/LiFePO batteries exhibit excellent long-cycle stability and cycle reversibility.

High-performance bulk graphite (HPBG) that simultaneously integrates superior electrical conductivity and excellent strength is in high demand, yet it remains critical and challenging. Herein a novel approach is introduced utilizing MOF-derived nanoporous metal/carbon composites as precursors to circumvent this traditional trade-off. The resulting bulk graphite, composed of densely packed multilayered graphene sheets functionalized with diverse cobalt forms (nanoparticles, single atoms, and clusters), exhibits unprecedented electrical conductivity in all directions (in-plane: 7311 S cm⁻¹, out-of-plane: 5541 S cm⁻¹) and excellent mechanical strength (flexural: 101.

In medical and biomedical fields, enzyme-mimetic nanomaterials have garnered significant interest as efficacious signal enhancers for biocatalyst-linked immunosorbent assays (BLISA). Despite the burgeoning enthusiasm, engineering artificial biocatalysts that exhibit both exceptional catalytic proficiency and pronounced colorimetric signal output remains a formidable challenge. Inspired by the heme structures and biocatalytic activities of horseradish peroxidase, we introduce the synthesis of vanadium single-atoms (SAV) coordinated artificial peroxidases as BLISA for highly sensitive and selective carcinoembryonic antigen (CEA) immunoassay.

Heavy metal ion pollution poses a serious threat to the natural environment and human health. Photoreduction through Bi-based photocatalysts is regarded as an advanced green technology for solving environmental problems. However, their photocatalytic activity is limited by the rapid recombination of photogenerated e and h pairs and a low photo-quantum efficiency.
