Abstract The harvesting of ocean wind energy for triboelectric nanogenerators (TENGs) is greatly influenced by the contact electrification (CE) capability, charge retention characteristics, and harsh marine environment. In this work, four highly water‐stable metal–organic frameworks, including MIL‐101(Cr), UiO‐66, ZIF‐8, MOF‐303, are doped into PVA/Ta layers to modulate their CE retention, resistance environments. capability compared at multiple scales electronic, atomic, molecular levels using DFT calculation. combined effect pyrazole ring ─COO─ group contributes highest tribopositivity PVA/Ta/MOF‐303. Besides, reduced HOMO–LUMO gap increased HOMO level make it easier electrons in PVA/Ta/MOF‐303 transfer. Meanwhile, MOF‐303 with high capture located deep can serve as traps reduce dissipation rate. Hence, density PVA/Ta/MOF‐303‐based TENG (PTM‐TENG) 90% RH reaches 361.43 µC m −2 . Hydrogen bonding, coordination effects, electrostatic interactions endow excellent mechanical, anti‐swelling, anti‐aging properties. Finally, PTM‐TENG assembled a self‐powered sewage treatment system, generation ·OH ·O 2 − enables realize water sterilization rate (99.99%) efficient organic pollutant degradation (>95%) within 20 min.

Green energy transition has supposed to give a huge boost the electric vehicle rechargeable battery market. This generated compelling demand for raw materials, such as cobalt and nickel, which are key common constituents in lithium-ion batteries (LIBs). However, their existing mining protocols concentrated localization of ores have made nickel mineral conundrums, supplies experience shortages, threaten slow progress renewable transition. Aiming contribute sustainable recycling these valuable metals from LIBs wastewater, this work, we explore use four mixed matrix membranes (MMMs) embedding different metal–organic frameworks (MOFs), i.e., MIL-53(Al), MIL-53(Fe), MIL-101(Fe), {SrIICuII6[(S,S)-serimox]3(OH)2(H2O)}·39H2O (SrCu6Ser) polyether sulfone (PES), recovery cobalt(II) nickel(II) metal cations cobalt–nickel aqueous solutions containing interfering ions. Whereas neat PES membrane slightly contributes adsorption ions, showing reduced removal efficiency values 10.2 9.5% Ni(II) Co(II), respectively, inclusion MOFs polymeric substantially improves performances. The MOF@PES MMMs efficiently remove water, with MIL-53(Al)@PES being one that presents better performance, up 95% Co(II). Remarkably, SrCu6Ser@PES exhibits outstanding selectivity toward compared ones, efficiencies 63.7 15.1% Co(II) Ni(II), respectively. Overall, remarkable efficiencies, versatility, high environmental robustness, cost-effective synthesis shown by family situate them among best adsorbents extraction kind contaminants.

Metal–organic frameworks (MOFs) are often used as proton conductor fillers to enhance the conductivity of hybrid membranes. It is interesting but still challenging discuss influence molecular morphology and distribution carriers within MOFs on their exchange membranes (PEMs) overall performance. In this work, two types imidazole-loaded conductors were synthesized based MIL-101(Cr), with one containing free imidazole molecules other coordinating Cr-metal sites. Furthermore, series composite (CPM/IM-x CPM@IM-x, x = 1, 2, 3) fabricated using filler a cross-linked poly(vinyl alcohol) (CL-PVA) that contains both hydrophilic hydrophobic structures matrix. The CPM/IM coordinated exhibit significantly enhanced water affinity, stability, ion capacity. This mainly due improving two-phase dispersion, promoting deprotonation, facilitating low-energy-barrier transport, while CPM@IM relatively lower higher activation energy (Ea). Surprisingly, CPM/IM-2 membrane can reach up 2.7 × 10–2 S cm–1 at 85 °C 90% RH, lowest Ea 20.9 kJ/mol. remarkable performance indicates more efficient H+ transportation. Moreover, single-cell power density 89.7 mW cm–2, proving it exhibits high potential application prospects for hydrogen-based fuel cells.
