Furthermore, the intervention of CNTs transform the electronic structure of NiFe-LDH to further enhance OER activity, while solve the problems of poor electrical conductivity and aggregation of FePc. The prepared bifunctional catalyst FePc-LDH@CNTs exhibits preeminent electrocatalystic performance for ORR (E1/2 = 0.815 V) as well as OER (Ej=10 = 1.447 V).

Moreover, the liquid RZABs based on the FePc-LDH@CNTs demonstrate a significant specific capacity (810.4 mAh g-1) and robust stability (840 h), superior to commerical Pt/C + RuO2. As flexible RZABs, it maintains superb stability (100 h) and can drive water splitting to produce H2 smoothly. In addition, the reasons for the failure are dissected by analyzing the components of the battery after cycles.

However, the application of g-C3N4 and CN as sulfur hosts in NaSBs is hindered by their inherently low electrical conductivity and high energy barriers for Na+ migration. In this work, the density functional theory (DFT) and ab-initio molecular dynamics (AIMD) simulations reveal that the Na atoms have a tendency to favor a \"self-building\" process, which result in the formation of Na@g-C3N4 and Na@CN after the initial discharge. Notably, within the Na-embedded substrates, the trapped Na effectively balances the polarity of the N6 cavity, accompanied with a moderate binding with NaPSs and effective dissociation of Na2S. Electronic structure analysis reveals that the incorporation of Na significantly enhances the electrical conductivity of g-C3N4/CN and creates efficient channels for Na+ diffusion. This promotes the transport of Na+ with lower migration energy barriers (0.61 and 0.69 eV) in Na@g-C3N4 and Na@CN, thereby accelerating the dynamic transformation and desorption of intermediates. Overall, this study offers new insights into the structural evolution mechanisms of g-C3N4 and CN, and provides valuable guidance for the subsequent design and experimental research of high-performance Na-S battery catalysts.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"701 ","pages":"138780"},"PeriodicalIF":9.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the poor distribution of MOFs within polymer matrices and their limited proton transport pathways remain substantial challenges. In this work, a silane-networking strategy is proposed to construct silane-networked UiO-66-NH₂ (Si-UiO-66-NH₂), which serves not only as a spatial barrier through Si-O-Si crosslinking to inhibit self-aggregation but also as a proton-conductive mediator via superficial polar groups that enhance proton transport. The resulting silane-networked MOFs exhibit enhanced interfacial compatibility with the Nafion matrix, thereby promoting uniform dispersion of MOF particles throughout the polymer network. More impressively, the abundant polar functional groups of silane-networked MOFs reorganize the hydrophilic/hydrophobic microphase-separated structure of the membrane, facilitating the formation of continuous, low-energy-barrier proton transport channels. Benefitting from these structural enhancements, the composite membranes exhibit excellent performance, including a low swelling ratio of 15.7 % at 80 °C and high proton conductivity (236.4 mS·cm-1). When applied in a water electrolyzer, the optimized Si-UiO-66-NH₂@Nafion membrane results in a significantly reduced cell voltage of 1.887 V at a current density of 3.0 A·cm-2 at 80 °C, representing a 15.3 % decrease compared to the system using recast Nafion.

Concerns about material degradation or oxidation to toxic chromate necessitate an understanding of chromia/aqueous interfaces, beginning with their hydroxylation and hydration behavior. Vibrational sum-frequency generation spectroscopy (vSFG) provides specific molecular-level information about water at the oxide/aqueous junction with high surface selectivity. To overcome the strong absorber problem typical of certain metal oxides in the UV-visible range during nonlinear optical studies, we employed molecular beam epitaxy to deposit transparent, epitaxial nanofilms of Cr2O3 with (001) crystalline orientation on sapphire (Al2O3 (001)) substrates, as confirmed by atomic force microscopy and X-ray diffraction. vSFG spectra of the air and water interfaces of the Cr2O3 (001) films reveal hydroxyl features corresponding to both dissociated and molecular water on the surface. In contrast to the dangling hydroxyls found on the bare Al2O3 (001) substrate, the hydroxyl groups on the deposited Cr2O3 (001) nanofilm do not readily undergo isotopic H/D exchange when exposed to varying forms of D2O under ambient conditions. When considering the chemistries of the corresponding trivalent cations in aqueous solution, the finding is at variance with their similar acidities and proton exchange dynamics but consistent with markedly slower inner-sphere water ligand exchange of hexaquo Cr3+. This finding challenges the idea that proton and water exchange at the water/Cr₂O₃(001) interface are solely correlated, driven by the strength of metal-bridging oxygen bonds and surface hydroxyl distribution, without direct causation.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"701 ","pages":"138631"},"PeriodicalIF":9.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144815511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydrophilic modifier with high zincophilicity, usually affords uniform Zn deposition but exhibits intrinsic limitations in repelling water molecules, while hydrophobic modifiers shows excellent water-resistance.

However, two fundamental challenges impede its practical application: irreversible nanosheet restacking during synthesis seriously compromising Na+ ion diffusion, and structural collapse during cycling causing catastrophic capacity fade. Addressing these limitations, we proposed a metal-organic framework (MOF)-mediated structural transformation strategy to construct hierarchical hydrangea-like NiPS3/C microspheres through carbonization and phospho‑sulfurization of Ni-BPDC (BPDC = 4,4'-biphenyldicarboxylic) precursor. The unique architecture manifested multiple advantageous features: (i) randomly oriented NiPS3 nanosheets ensuring abundant electrochemical active sites and efficient electrolyte permeation; (ii) interconnecting conductive carbon networks enabling ultrafast electron transport; and (iii) spatially distributed carbon nanoparticles helping accommodate volume changes. Benefiting from these synergistic effects, the developed NiPS3/C electrode delivered outstanding electrochemical performance, including high specific capacity (1107.8 mAh g-1 at 0.1 A g-1) and superb cycling stability (98.2% capacity retention after 1000 cycles at 5.0 A g-1). Through in-situ/ex-situ structure diagnostics, we decoded the dynamic phase evolution during sodiation/desodiation, revealing a conversion-alloying mechanism. This work established a general strategy for designing high-performance MOF-derived anode materials for energy storage systems.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"701 ","pages":"138777"},"PeriodicalIF":9.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
