“…53 In addition, the use of other 1D structural materials as the supporting framework, such as plant fiber, polydopamine nanotubes, etc., has also been proven to be an effective strategy. [54][55][56][57] Electrospinning technology offers another direct and efficient method distinct from chemical synthesis. It is currently a straightforward and effective means of producing nanofibers, with characteristics such as high specific surface area, porosity, and fiber uniformity, finding widespread applications across various fields.…”

“…Besides, the collapse of the MOF structure will also cause the aggregation and coarsening of metal nanoparticles and their nonuniform distribution in MOF-derived carbons. 36 Last but not the least, most adsorbent materials are nonantibacterial, thus reducing their treating efficiency and service life since water environment is normally full of bacteria. The above-mentioned defects will result in the poor cyclic stability of adsorbents.…”

“…Unexpectedly, the collapse of MOFs during the pyrolysis of organic ligands will make MOF derivatives scarcely maintain the original MOF morphologies, such as the decrease of specific surface area, micropore volume, and interparticle porosity as well as the blockage of micropores.

Metal organic framework (MOF)-derivatives have a larger specific surface area, higher porosity, tunable pore size, higher conductivity, good stability, more exposed active species, etc., but few literature are reported about their application potential in micropollutant separation and removal. In view of this, a robust MOF derivative-based photocatalytic superhydrophobic membrane (D6/ TiO 2 /MoS 2 /NiCo-NC/PVDF) was successfully fabricated for the first time through solvothermal synthesis and chemical modification, combined with a negative pressure-assisted loading approach. (1) The MoS 2 -doping strategy effectively avoided the collapse and coarsening of cauliflower-like MOFs during the calcination phase and simultaneously ensured the uniform distribution of metal particles in MOF-derived carbons. (2) The synergistic catalysis of the NiCo-MOF derivative, MoS 2 , and TiO 2 enhanced the transfer efficiency of electrons and free radicals, achieving efficient in situ degradation of pesticides and pharmaceutical and personal care products. (3) The introduction of sodium alginate greatly improved the adhesion between the coating and polyvinylidene fluoride (PVDF) membrane and simultaneously enhanced the growth of MOFs through complexation. (4) The cauliflower-like MOF-derived carbon skeleton with higher surface areas and micronanoporosity combined with a heterogeneous MoS 2 structure provided a large specific surface area and enough adsorption sites for various pollutants. High thermal calcination treatment greatly enhanced MOF growth rate, thus resulting in a flaky structure with high regularity and a large specific area. ( 5) The ultralow surface energy of interlaced siloxane molecules endowed the hybrid membrane with robust superhydrophobicity and superoleophilicity, always maintaining superhydrophobicity after long-time photodegradation. The final membrane achieved continuous emulsion separation and a photocatalytic self-cleaning property. The separation efficiency of the hybrid membrane for emulsions was still up to 97% after reuse for 120 cycles, and it could degrade 86.5% PRO, 90.1% ACE, 92.1% ASP, and 94.3% SMZ, respectively, with the initial concentration of 10 mg/L. The driving forces for oil−water separation and decontamination of the D6/TiO 2 /MoS 2 /NiCo-NC/PVDF membrane mainly involved the grasping forces of dodecamethylcyclohexasiloxane, capillary force of inner pores, electrostatic interaction, hydrogen bond interaction, partial p-π conjugation, van der Waals force, and lipophilicity.

ZnS has acquired increasing attention for high‐performance PIBs anode because of its remarkable theoretical capacity, and redox reversibility for conversion reaction. However, the larger volume variation and delayed reaction kinetics for the ZnS in the discharge/charge processes lead to pulverization and severe capacity degradation. Herein, the trumpet‐like ZnS@C composite was synthesized by template method by using sodium citrate as carbon source followed by vulcanization process. As potassium ion batteries (PIB) anode, ZnS@C composite exhibits good rate performance and long life (stable reversible capacity of 107.8 mAh/g over 2000 charge‐discharge cycles at 5 A/g and high reversible capacity of 310 mAh/g at 0.1 A/g). The outstanding electrochemical performance of the ZnS@C composite is ascribed to its unique structure, which can mitigate the volume expansion of ZnS in the charge discharge process, expand the contact area between the electrode and electrolyte, and improve the conductivity of electrode materials by the introduction of carbon layer. This method of synthesizing trumpet‐like ZnS@C composite provides an important strategy for obtaining potassium ion batteries anode with long cycle.
