As a potential material for the RWGS reaction, Mo₂C faces the challenges of high dispersibility and synthesis efficiency. Here, the Mo₃N₂-Mo₂C heterojunction encaged in N-doped carbon matrix is synthesized using in situ carbonization method, which exhibits high activity under mild temperature. The CO₂ conversion is 38.3%, the selectivity of CO is 99.1% upon 410 °C. The Space Time Yield is 17333.6 mgCO g_cat ^-1h^-1 (619.06 mmol g_cat ^-1 h^-1) under 450 °C, and WHSV = 240 000 mL g_cat ^-1 h^-1, which is superior than traditional catalysts such as Cu-Zn-Al and noble metal catalysts. The catalyst shows 99.9% selectivity of CO, and maintaining equilibrium conversion for 200 h under 500 °C. The structure-performance relationship studies indicate the synergistic effect of Mo₂C-Mo₃N₂ heterojunction active sites enhances H₂ adsorption and dissociation significantly, which boosting the H assisted CO₂ reduction reaction. Moreover, the N-doped carbon cage confined environment greatly boosts the catalyst stability. This work provides a simple and feasible strategy for the synthesis of highly dispersed Mo₂C-Mo₃N₂ heterojunction active site for CO₂ hydrogenation reaction, and a way to boost the H₂ activation capacity of Mo₂C catalyst.</p>","PeriodicalId":228,"journal":{"name":"Small","volume":" ","pages":"e08722"},"PeriodicalIF":12.1,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224636","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}

Nevertheless, the intermediate spin (IS) configuration of Co<jats:sup>2+</jats:sup> sites, featuring partially occupied d orbitals, triggers suboptimal adsorption with oxygenated species. In this work, selenium incorporation into CoCr layered double hydroxides (LDH) is demonstrated to induce spin‐state transition, activating inert sites and stabilizing the low‐spin (LS) Co<jats:sup>2+</jats:sup> configuration. The low spin‐state materials exhibit superior electrocatalytic activity, requiring overpotentials of merely 284.0 and 130.0 mV for oxygen and hydrogen evolution reactions, respectively, at 10 mA cm<jats:sup>−2</jats:sup>, while maintaining excellent durability over 168 h. The lowered e<jats:sub>g</jats:sub> occupancy in low‐spin Co<jats:sup>2+</jats:sup> results in electronic asymmetry and enhances electron density at the metal center. This electronic configuration facilitates robust Co 3d‐O 2p orbital hybridization, which enhances the adsorption of oxygenated intermediates by elevating the d‐band center toward the Fermi level, optimizing adsorption energetics. Moreover, low‐spin Co<jats:sup>2+</jats:sup>’s paired d‐orbital electron configuration minimizes high‐energy antibonding e<jats:sub>g</jats:sub> orbital occupancy, enhancing crystal lattice stability. Overall, this work establishes that spin state modulation in transition metals significantly lowers reaction energy barriers, offering a promising strategy for developing high‐performance electrocatalysts.","PeriodicalId":228,"journal":{"name":"Small","volume":"74 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145215765","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, the limited supply and high cost of rare indium pose challenges to the sustainable development of PSCs. In this study, sputtered tantalum-doped tin oxide (TTO) films with post-annealing in H₂ (TTO-H₂), are proposed as an attractive alternative to ITO electrodes in PSCs. It is demonstrated that TTO films post-annealed in H₂ atmosphere exhibited lower sheet resistance of 91.8 Ω sq⁻¹, with a higher carrier concentration of 6.51 × 10²⁰ cm⁻³, and a higher mobility of 6.96 cm² V⁻¹ s⁻¹, compared to TTO films post-annealed in O₂ and N₂ atmospheres. The mechanism behind the improvement in electrical characteristics is revealed. Indium-free inverted PSCs using TTO-H₂ bottom electrodes are constructed. High-quality TTO-H₂/MeO-2PACZ/perovskite interface is demonstrated with advantages of higher built-in electric field, lower defect state density, and improved carrier transport ability, compared to the reference ITO/MeO-2PACZ/perovskite interface. Thus, the prepared PSCs using TTO-H₂ electrodes exhibit improved photovoltaic performance compared to reference ITO-based PSCs: the open-circuit voltage (<i>V</i>_oc) is enhanced from 1.100 to 1.134 V; and the power conversion efficiency (PCE) is enhanced from 20.58% to 20.77% with 1% increase.

Existent methods, involving harsh acids or corrosive reagents, typically raise production costs, pose safety hazards, and cause unwanted carbon loss, reducing precursor utilization efficiency. To overcome these issues, this study introduces a mild, environmentally friendly, and scalable approach utilizing selective sulfonation of raw bamboo. This method enhances lignin hydrophilicity, facilitating partial delignification via solid-liquid separation. Subsequent carbonization of the cellulose-enriched precursor yields HC with thin-layered pseudo-graphitic domains, enlarged interlayer spacing, and dense closed-pore structures. The resulting anodes achieve a reversible capacity of 348 mAh g⁻¹ at 30 mA g⁻¹ with an initial Coulombic efficiency of 84.2%, excellent rate capability (241 mAh g⁻¹ at 900 mA g⁻¹), and superior cycling stability (97.8% capacity retention after 500 cycles at 500 mA g⁻¹). Ex situ XRD and XPS analyses further indicate an adsorption-intercalation/filling mechanism. This sustainable pretreatment not only enhances electrochemical performance but also supports efficient lignosulfonate recovery, promoting comprehensive and high-value utilization of lignocellulosic biomass in energy storage applications.","PeriodicalId":228,"journal":{"name":"Small","volume":"33 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145216245","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}

A heterometallic Bi₄Ti₁₂ oxo cluster is constructed with Keplerian-type architecture as a molecular platform for post-synthetic reactivity studies. Detailed mass spectrometry analysis confirms its exceptional dissolution stability and complete surface alkoxy ligands exchangeability. Interestingly, spin-coated thin films of Bi₄Ti₁₂ oxo clusters exhibit significant solubility contrast after ambient condition hydrolysis. Accordingly, electron-beam irradiation is applied to accelerate the cluster hydrolysis in exposed areas to enable fine lines patterning, with the hydrolysis-condensation pathways of irradiated Bi₄Ti₁₂ oxo clusters being demonstrated by comparative spectroscopic analyses. Finally, 20 nm critical dimension (CD) lines can be fabricated using this method under an expose energy of 130 µCcm⁻². Therefore, this work not only constructs a Keplerate cluster family with interesting complete surface ligand exchange behavior, but also provides a new metal hydrolysis-driven lithography strategy for the direct patterning of metal oxide nanostructures.","PeriodicalId":228,"journal":{"name":"Small","volume":"78 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145216247","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, the efficient capture and separation of Xe/Kr by MFM-520, which strikes a remarkable stability toward 1750 kilogray (kGy) γ-irradiation, is reported.
