Here, we systematically compare dark electrochemical and illuminated photoelectrochemical anodic etching and thinning of mechanically exfoliated MoS2, WS2, MoSe2, and WSe2 flakes as a function of applied potential, electrolyte pH, irradiance, and oxidation time. In the dark, oxidation initiates at defect-rich flake edges and produces lateral etching without appreciable basal-plane thinning. The oxidation peak potentials exhibit significantly different pH dependences for sulfide- and selenide-based TMDs, revealing chalcogen-dependent oxidation chemistry and kinetics. Under illumination, an additional oxidation regime emerges at lower anodic potentials, in which multilayer n-type MoS2, WS2, and MoSe2 undergo vertical thinning with minimal lateral etching, whereas no thinning is observed for p-type WSe2. This observation, together with strong suppression of thinning by sacrificial hole acceptors, indicates that photogenerated holes accumulated in the upper layers of n-type TMDs drive a photoelectrochemical self-oxidation process. Tuning the bias, irradiance, and oxidation time enables controlled conversion of initially nonuniform multilayer flakes into homogeneous few-layer structures, while focused laser excitation yields spatially localized thinning and patterning. In addition to elucidating stability windows and oxidation mechanisms of TMD photoelectrodes, these results provide a versatile strategy for controllably tuning the thickness and morphology of layered semiconductors.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"56 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional catalysts lack the electronically asymmetric sites needed to drive both steps efficiently. Herein, a bifunctional Cu+–Ov–Ce3+ interfacial frustrated Lewis pair (FLP) is constructed by loading Cu onto La doping CeO2. La doping introduces additional oxygen vacancies (Ov) and Ce3+ species, thereby enriching the Ov–Ce3+ sites. Systematic characterizations (XPS, EPR, XAS, TPD, in situ FTIR) combined with DFT calculations reveal that Cu+ sites are responsible for α-H elimination to form 6-hydroxyhexanal (6-HA), whereas the cyclization reaction is driven by the FLP composed of Ov–Ce3+ and adjacent lattice oxygen. La incorporation lowers the energy barrier and enhances FLP formation. Under optimized conditions (3 wt % La, 280 °C, weight hourly space velocity of 1.5 h–1), a ε-CL yield of 61.17% is achieved with good stability over 120 h. From these findings, the interfacial bifunctional mechanism is clearly elucidated, and a defect engineering strategy for decoupling interfacial components is demonstrated, providing a rational approach to the design of multifunctional catalysts for tandem reactions.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"233 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we employ single-sided nuclear magnetic resonance (SS-NMR) to probe the in situ diffusion dynamics of water within solid-state nanochannels (SSNs) functionalized with UiO-66 metal–organic framework (MOF). We systematically compare two distinct synthetic protocols: a one-pot (OP) interfacial growth and a counter-diffusion (CD) method. By deconvoluting the NMR signal attenuation, we isolate a minor slow diffusion component corresponding to intraparticle micropores and a dominant fast diffusion component representing interparticle constructional porosity. Our results show that OP growth produces large particle agglomerates and poorly connected pores with narrow bottlenecks, forcing water along highly tortuous paths. Furthermore, leveraging the pH-responsive surface charge of UiO-66, we find that water mobility in the well-connected CD nanoarchitecture varies measurably with pH, consistent with a surface-charge effect, whereas OP membranes show a weaker, nonmonotonic variation, consistent with dominant geometric obstruction. These findings link nanochannel architecture directly to local water mobility and identify constructional porosity as a structural parameter to consider in MOF-based nanofluidic membranes.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"12 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, polarization-resolved low-temperature photoluminescence (PL) combined with first-principles G0W0+BSE calculations probes the intralayer and interlayer excitonic fine structure of this Ruddlesden–Popper perovskite. The low-energy multiplet is consistent with the intralayer excitonic fine structure governed by electron–hole exchange, crystal symmetry, and layer inequivalence in the two-layer unit cell, without requiring Rashba effects or exciton–polaron mechanisms as its primary origin. The weak doublet about 40 meV higher is best accounted for by interlayer excitons based on its energetics, splitting, and real-space character. Distortion-induced mixing of interlayer excitons with bright intralayer excitons provides a plausible explanation for the observed interlayer PL intensities and nearly orthogonal polarizations. These results support a layer-resolved excitonic picture encompassing both intralayer and interlayer states in (PEA)2PbI4.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"11 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
