However, the aggregation of MOFs, particularly at the nanoscale, frequently leads to defects at the filler–polymer interface, making it difficult to form continuous molecular transport channels. Here, a series of necklace-like MOF@carbon nanotubes (CNTs) were synthesized using a straightforward one-pot technique. Specifically, CNTs as a “lead wire” with substantial aspect ratios were first used to induce the self-assembly growth of MOFs as “beads” along the CNTs' longitudinal axis, for the preparation of necklace-like MOF@CNTs. Subsequently, necklace-like MOF@CNTs MMMs were obtained by interfacial polymerization or solvent evaporation. MOF@CNTs have good dispersibility in the polymer matrix and the MOFs within the necklace are in close contact and effectively link the MOF window to create micrometer-scale continuous molecular transport channels that can improve the separation performance of MMMs. For ZIF-90/PA mixed matrix nanofiltration membranes, the water permeability of M-ZIF-90@CNTs (27.15 L m<small><sup>−2</sup></small> h<small><sup>−1</sup></small> bar<small><sup>−1</sup></small>) is greater than that of M-0 (8.11 L m<small><sup>−2</sup></small> h<small><sup>−1</sup></small> bar<small><sup>−1</sup></small>). Furthermore, the dye rejection efficiency has been increased from 96.60% of M-0 to 99.55% of M-ZIF-90@CNTs and the rejection of NaCl remains relatively low across all nanofiltration membranes, at less than 10%, which has significant advantages in the field of dye/salt separation. For ZIF-90/PSf mixed matrix gas separation membranes, MPSf-ZIF-90@CNTs also exhibit remarkable CO<small><sub>2</sub></small>/N<small><sub>2</sub></small> separation selectivity. Importantly, the proposed strategy for preparing necklace-like MOF@CNTs is universally applicable, and can be easily extended to other MOFs, such as ZIF-8, MOF-801, UiO-66, and UiO-66-NH<small><sub>2</sub></small>, representing a universal strategy for constructing necklace-like MOF@CNTs structures.</p>","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 4","pages":" 1041-1050"},"PeriodicalIF":0.0,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/lf/d5lf00016e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbon fibers offer unique benefits in electrochemical recovery processes due to their high surface area, excellent conductivity, mechanical durability, and compatibility with low-cost production. The optimized conditions, including a deposition potential of 4 V, pH 3.5, and temperature of 60 °C, achieved a high nickel recovery efficiency of 90%, with minimal energy consumption at 3 kW h per kilogram of nickel. This efficiency was verified through Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX) analyses, which revealed uniform and dense nickel coatings on the carbon fibers, even under continuous operation. Fourier Transform Infrared Spectroscopy (FTIR) and X-ray diffraction (XRD) confirmed successful nickel deposition and modifications to the carbon fiber surface chemistry, enhancing the adsorption and reduction of nickel ions. Using carbon fiber electrodes in this process addresses several limitations in traditional electrode materials by reducing costs, improving scalability, and supporting continuous, large-scale nickel recovery.

Here, we explore heterostructures of tungsten disulphide with monocrystalline thin flakes of the organic compound pyrenemethylammonium chloride. The ionic character of the organic compound enables controlled fabrication of heterostructures <em>via</em> exfoliation of single crystals, thereby minimizing structural disorder in the molecular compound. In order to explore the optical properties and the photoexcitation dynamics related to the heterointerface, we employ time and polarization resolved photoluminescence spectroscopy. Evidence for electronic coupling is provided by three experimental findings: first, a faster decay of the luminescence of the organic compound in the region of the heterostructure indicates exciton or charge transfer, which is also surprisingly efficient for the structurally relaxed localized excimer state. Second, we find that the organic compound introduces a polarization anisotropy into the emission of tungsten disulphide, potentially due to the lowering of symmetries in the band structure. Third, we identify a weakly emissive feature at an energy around 1.7 eV, which could be related to an interfacial state.

While the Ru(0001) surface is well-studied, hydrogen interaction with the Ru (10<img>1) and Ru (10<img>0) facets remains mostly underexplored. In this contribution, we use density functional theory calculations to investigate hydrogen adsorption and dissociation and provide insights into the adsorbed hydrogen role in catalytic polyolefin plastic hydrogenolysis. We start our investigation by exploring all the unique surface and subsurface sites for hydrogen adsorption and dissociation and identify hcp and higher hollow as the most favorable atomic hydrogens adsorption sites on the Ru (10<img>1) and Ru (10<img>0) surfaces, respectively. We find that atomic hydrogen can easily migrate on these surfaces to achieve the most stable arrangement at different coverages. We then combine these findings with <em>ab initio</em> thermodynamics and microkinetic modeling to build surface phase diagrams, which show that both surfaces are fully hydrogenated under typical catalytic conditions. We then study how the presence of a full hydrogen coverage affects the adsorption and dehydrogenation of butane as a proxy for polyethylene, as these are the initial steps in the catalytic hydrogenolysis of polyolefin plastic waste. We find that the adsorption energy of butane decreases when the two surfaces are fully hydrogenated but adsorption remains favorable. We then investigate two possible mechanisms for the dehydrogenation step. The most favorable dehydrogenation mechanism involves the reaction of a surface hydrogen with an alkane hydrogen to produce H<small><sub>2</sub></small> gas and an adsorbed alkyl radical.
