Herein, a thermodynamic-driven metal cation confined in-situ reduction strategy was used to construct highly dispersed Pd nanoparticles on CoAl-LDHs (Pdx@CoyAl-LDHs, x = 0.5-2.5 wt%, y = 2-4) without employing external reductants. Driven by the intrinsic low oxidation potential of atomically distributed Co2+ within the LDHs laminates, the adsorbed Pd2+ species are in-situ reduced and anchored, producing small-sized and uniformly dispersed Pd nanoparticles supported on the CoAl-LDHs. Moreover, the electronic metal-support interaction (EMSI) between active Pd and CoAl-LDHs support promoted the formation of bifunctional metal-acid active sites within the Pdx@CoyAl-LDHs catalysts. The catalytic reaction kinetic study revealed that the optimal Pd2@Co3Al-LDHs presented excellent catalytic performance toward CyO reductive amination, affording a 95.1% cyclohexylamine selectivity and a high reaction rate of 469 mmol·gPd-1·h-1. Such superior catalytic performance was attributed to the synergistic catalysis of bifunctional metal-acid sites based on the structure-performance relationship analysis, which promoted the adsorption and activation of CyO, H2, NH3 and Schiff base intermediate, and effectively suppressed the side reactions such as over-hydrogenation. The corresponding reaction pathway and catalytic mechanism for CyO reductive amination were elucidated. Furthermore, the catalyst exhibited robust cycling stability and broad substrate generality for the reductive amination of various carbonyl compounds, providing a facile and green paradigm for designing bifunctional catalysts for sustainable biomass upgrading to valuable primary amines.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"129 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853805","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, its practical implementation is hindered by the competing hydrogen evolution reaction, insufficient nitrate adsorption at active interfaces, and poor long-term stability of noble metal catalysts. Herein, we present an ultra-stable Pd@S-1 electrocatalyst in which size-tunable Pd clusters are encapsulated within silicalite-1 (S-1) zeolite through a one-pot hydrothermal synthesis. The S-1 zeolite serves a dual role: it spatially confines Pd species to prevent aggregation and leaching, and establishes a microporous microenvironment that enriches nitrate near the active sites, thus promoting reaction kinetics and suppressing HER. The optimized Pdm@S-1 catalyst with an average Pd size of 2.08 nm exhibits superior NO3RR performance in neutral electrolyte, delivering an ammonia production rate of (133.38 ± 16.76) mg h−1 mgPd−1 at −1.1 V vs. RHE. Notably, Pdm@S-1 preserves nearly unchanged catalytic performance over 100 successive cycles, evidencing outstanding durability. These findings highlight the importance of coupling active metal sites with a confinement induced reactant-enrichment effect, and offer a viable design principle for durable and efficient electrocatalysts for nitrate reduction to ammonia.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"44 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853761","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}

Layered zeolites have flexible structures that can be intercalated, expanded, delaminated and disorganized but proved difficult to exfoliate into monolayer dispersions in solution. Exfoliated zeolite layers can be used for the preparation of advanced materials that are not possible or difficult to obtain with the other 3D and 2D forms including intimate hybrids and composites, films, membranes and nano-devices. Direct exfoliation of several 2D zeolites has been achieved recently by treatments with suitable solutions, e.g. tetrabutylammonium hydroxide (TBAOH). However, 2D zeolite exfoliation is still a problem needing solving since the yields vary and depend on sample preparation, while some 2D zeolites do not exfoliate at all. The proposed likely reasons are crystal/layer intergrowths, which are difficult to control. The goal of this article is to report unexpected findings about exfoliation of siliceous 2D ferrierite precursor with 0.95 nm thick nanosheets, denoted ZSM-55. It does not exfoliate in TBAOH but adding Al to its synthesis gel generates new exfoliable layers, denoted bifer, with analogous planar unit cell but doubled thickness. This is a clear lead to extend the investigation to other 2D zeolites, to study the effect of adding Al to their synthesis mixture for the possibility of obtaining exfoliable layers. In the present case, increasing the amount of added Al produces more bifer in the mixture with ZSM-55, then pure bifer is obtained at Si/Al in the gel equal to 16/1, while for Si/Al = 10 3D ferrierite is produced. Similar transformations from multilayered precursor to exfoliable monolayers to 3D framework occur for MCM-22 (zeolite MWW) but without changing the layer thickness. Bifer materials separated from ZSM-55 by exfoliation and synthesized directly have comparable high Al content based on FTIR. ZSM-55 left after bifer removal by exfoliation has low Al content, emphasizing the primary role of Al in the bifer formation and probably its exfoliability. Sampling during synthesis of the mixture shows that ZSM-55 forms before bifer but is preceded by an unknown intermediate phase which disappears and is thermally unstable. Exfoliated and isolated bifer has high mesoporous surface area and strong acid activity. The reasons for Al promotion of zeolite monolayers and exfoliability are not well understood.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"643 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853692","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}

In this work, we examine the two-electron reduction of a BN-fused dipyridylanthracene (BDPA, 1), providing access to a family of alkali-metal dianion salts, M2-12– (M = Li, Na, K, and Rb). Single-crystal X-ray diffraction reveals cation-dependent ion-pairing motifs, with solvent-separated ion products for Li and K and contact ion products seen for Na and Rb. Computational analysis shows that product stabilization is governed by partial charge transfer from the reduced BDPA core to the metal centers. Structural analysis further reveals substantial bond-length reorganization and increased curvature of the π-framework upon reduction, consistent with the emergence of quinoidal electronic delocalization. This transformation is accompanied by a pronounced redistribution of aromaticity, involving a loss of aromatic character of the pyridyl groups and the central anthracene ring, and an enhancement of aromaticity in the terminal rings, as supported by HOMA and NICS analyses. A comparison of the electronic structure of the dianion 12– with those of isoelectronic dianionic all-carbon (M12–) and neutral BN-fused N,N-dihydrophenazine (M2) analogs demonstrates much more profound quinoidal character of 12–, signifying how the dearomatization and delocalization of charge is effectively supported by ‘B–N for C–C’ substitution. Together, these results demonstrate that two-electron reduction can be exploited to trigger dramatic changes in charge distribution and aromaticity, which directly impact the structural and spectroscopic properties of B–N Lewis pair functionalized PAHs.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"40 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853691","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}

Mechanical grinding triggers an unprecedented mechanochemical structural isomerization, converting a C,N-coordinated pyridyl-aminooxycarbene (NCN-type) into a C,O-coordinated diaminocarbene (OCN-type) via a reversible carbene ligand switching (NCN ⇄ OCN).

Conventional hydrothermal synthesis regards the plateau in macroscopic crystallinity, termed the “late stage of crystallization”, as the endpoint, overlooking atomic-scale evolution. This work reveals that the framework of NaY zeolite remains dynamic beyond this plateau, undergoing a directed rearrangement of the Si–Al distribution (decrease in Si(0Al) units and increase in Si(3Al) units). This “dynamic late stage of crystallization” provides a critical window for editing zeolite framework at the final synthetic step. Based on this, a “dynamic late-stage editing” strategy is proposed that introduces target elements during this stage to enable in situ framework modification. The editing outcome is inherently element-dependent. Silicon editing achieves framework optimization by altering the Si–Al redistribution pathway, synergistically increasing the framework Si/Al ratio and forming a silica-rich surface layer, thereby substantially enhancing thermal stability. Iron editing induces heterogeneous functionalization, with surface-enriched iron species forming a multiphase structure, reversing the decreasing trend of Si(0Al) units and tailoring a Lewis-acid-rich environment.

The intimate coupling of ZnS and SnS2 induces a robust built-in electric field at the heterojunction interface. This field acts as an “ion rectifier”, thermodynamically lowering the nucleation overpotential and kinetically accelerating Zn2+ transfer. Furthermore, the tailored cubic architecture eliminates localized electric field hotspots and buffers mechanical stress during the plating and stripping processes. Owing to this synergistic regulation of both electronic structure and spatial morphology, CHZS@Zn symmetric cells exhibit highly stable cycling for over 1200 hours at 1 mA cm−2 with a low overpotential of 45 mV. When coupled with an α-MnO2 cathode, the resulting full cells demonstrate substantially enhanced rate capability and cycling stability.
