Conventional monometallic catalysts, however, are often constrained by an intrinsic trade-off between activity and selectivity and tendencies toward particle sintering and deactivation. To address these challenges, a metal–organic-framework (MOF) precursor was employed in a self-sacrificial templating route to fabricate highly dispersed, oxygen vacancies-tunable, bimetallic Cu<ce:inf loc=\"post\">x</ce:inf>Ni<ce:inf loc=\"post\">2–x</ce:inf>/CeO<ce:inf loc=\"post\">2</ce:inf> catalysts. By integrating comprehensive physicochemical characterization with in-situ spectroscopies, a systematic investigation was conducted to examine the effects of the Cu/Ni ratio and oxygen vacancy (O<ce:inf loc=\"post\">V</ce:inf>) concentration on 5-HMF hydrogenation were systematically investigated to elucidate structure–activity relationships. The results demonstrate that the Cu<ce:inf loc=\"post\">1.2</ce:inf>Ni<ce:inf loc=\"post\">0.8</ce:inf>/CeO<ce:inf loc=\"post\">2</ce:inf> catalyst achieves an optimal balance between O<ce:inf loc=\"post\">V</ce:inf> and metal site distribution, enabling nearly complete 5-HMF conversion and exclusive selectivity toward BHMF. Interfacial synergy facilitates Ni-mediated H<ce:inf loc=\"post\">2</ce:inf> dissociation and hydrogen spillover to Cu sites, while the O<ce:inf loc=\"post\">V</ce:inf> selectively adsorbs and activates the carbonyl of 5-HMF, suppressing furan-ring hydrogenation and other side reactions. Compared with prior reports, this work highlights the decisive roles of O<ce:inf loc=\"post\">V</ce:inf> and bimetallic interfaces in promoting substrate-selective adsorption, active-hydrogen supply, and side-reaction suppression. This strategy advances the high-value conversion of biomass platform molecules and provides a conceptual foundation for the rational design of green catalysts.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"2 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148767568","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}

Based on first-principles calculations, this paper systematically investigates the modulation effects of 36 elements on the electronic characteristics and magnetic properties of the BLG. To accurately handle the strong <ce:italic>d</ce:italic>-orbital correlation effect in transition metal-intercalated systems, the DFT + U method was employed throughout the study. Results show: Alkali/alkaline-earth metals are dominated by charge transfer; as atomic radius increases (Li → K, Be → Ca), interlayer coupling and the “energy level splitting” effect weaken regularly, leading to gapless metallic characteristics. Intercalation with Ti, V, Mn, Fe, and Co not only shifts the Fermi level upward and forms relatively flat energy bands (enhancing electronic localization) but also induces magnetism in the system. Main-group nonmetals (H, C, N, P, and Cl) trigger spin polarization through orbitals hybridization, broaden the distribution of hybridized energy bands, and form narrowed or isolated energy levels near the Fermi level. This study provides a quantitative guideline for regulating the metallicity, spin polarization strength, and bandgap properties of BLG, thereby facilitating the customization of graphene-based electronic and spintronic devices.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"37 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148690953","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}

Hexagonal boron nitride (<ce:italic>h</ce:italic>-BN), as a typical graphite-like two-dimensional material, can effectively capture and convert mechanical energy. However, its piezocatalytic performance is limited by its high symmetry structure and layered stacking. Therefore, the defect-engineered porous-<ce:italic>h</ce:italic>-BN is designed for piezocatalytic hydrogen evolution. The introduction of vacancies disrupts the symmetry of the pristine <ce:italic>h</ce:italic>-BN structure, endowing it with enhanced non-centrosymmetry that generates a built-in electric field under mechanical stress and thus facilitates charge carrier separation. Moreover, the defect engineering narrows the bandgap, while the piezoelectric effect bends the energy bands. This synergy overcomes the wide-bandgap limitation of <ce:italic>h</ce:italic>-BN, enabling it to catalyze the hydrogen evolution reaction (HER). Specifically, the porous-<ce:italic>h</ce:italic>-BN achieves a HER of 940.2 μmol g<ce:sup loc=\"post\">-1</ce:sup>h<ce:sup loc=\"post\">−1</ce:sup>, which is 4.65 times that of commercial-<ce:italic>h</ce:italic>-BN (202.2 μmol g<ce:sup loc=\"post\">-1</ce:sup>h<ce:sup loc=\"post\">−1</ce:sup>) without co-catalysis.
