Lithium metal batteries (LMBs), with high energy densities, are strong contenders for the next generation of storage systems. Nevertheless, unregulated growth lithium dendrites and unstable solid electrolyte interphase (SEI) significantly hamper their cycling efficiency raise serious safety concerns, rendering LMBs unfeasible real-world implementation. Covalent organic frameworks (COFs) derivatives have emerged as multifunctional materials significant potential addressing inherent problems anode electrode metal. This stems from abundant metal-affine functional groups, internal channels, widely tunable architecture. The original COFs, derivatives, COF-based composites can effectively guide uniform deposition ions by enhancing conductivity, transport efficiency, mechanical strength, thereby mitigating issue dendrite growth. review provides a comprehensive analysis derived employed challenges posed in LMB. Additionally, we present prospects recommendations design engineering architectures that render feasible practical applications.

Consecutive uranium extraction from seawater is a promising approach to secure the long-term supply of and sustainability nuclear energy. Here, we report an ultra-highly efficient strategy via studtite nanodots growth with impressive uranyl uptake capacity ~ 154.50 mg/g natural in 12 consecutive days (i.e., average for 12.875 mg/g/day). Uranyl can be extracted as under visible light reaction between adsorbed photogenerated H2O2 imine-based Covalent-Organic Framework photocatalysts. In detail, over Tp-Bpy, Tp-Bpy-2 Tp-Py multiple chelating sites, found which eluted readily, while Tp-Bd Tb-Bpy, transformed into nanorods that more inert elution. Abundant sites structural regulation COF photocatalysts are proved facilitate formation elution nanodots.

Electron delocalization is a versatile method to tune the electronic structure of materials for maximizing their performances. Herein, TPBD covalent organic frameworks (COFs) with controlled electron-delocalization characteristics (denoted as TPBD-R-COF, R = H, F, CN, and NO2) were synthesized by molecular engineering systematically investigate effect electron on photocatalytic performance. We found that performance can be enhanced modulating local in COFs. The activity TPBD-CN-COF more than 12 times greater TPBD-H-COF oxidative coupling amines imines, where yield product was increased from 8 99%. experimental results theoretical calculations revealed optimal electron-attracting group −CN shows highest charge separation efficiency transport rate, while excessive not better such properties. Our findings provide strategy design optimize COF-based catalysts.
