Here, a general two-stage morphology-structure-control strategy is presented to construct tandem built-in electric fields (BIEFs) embedded hollow bifunctional photocatalysts (Sv-chalcogenide hollow nanocage/NiCo2S4 heterojunctions, Sv represents sulfur vacancies, chalcogenides include ZnIn2S4, CdS, CdIn2S4). This strategy involves fabricating polyhedral cages via constraint epitaxy and embedding tandem BIEFs (consisting of intra-component and inter-component BIEF) within hollow nanocages through defect-mediated heterocomponent anchorage. The resulting hollow nanoreactors synergize multilight scattering/reflection with directional charge-transfer to boost photocarrier dynamics by stimulating plentiful carrier generation and driving continuous carrier localization and delocalized-electron transportation. Subsequently, the localized surface plasmon resonance (LSPR)-induced photogenerated electron excitation continuously collaborates with the intrinsic excitation for hot electron generation, thus improving the photothermal effect. Heterojunctions with efficient photothermal regulation optimize the pivotal intermediate adsorption/activation in selective alcohol oxidation coupled with H2 evolution, delivering unprecedented reactivity and broad alcohol substrate compatibility. This study provides a programmable framework for structurally designing BIEFs within hollow architectures, elucidating the substantial impact of morphology-structure control on photogenerated carrier dynamics and molecular catalytic behavior.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"72 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745724","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}

To address these issues, ZnF2 combined with V2C MXene composite (ZnF2/V2CTx) is in-situ synthesized from V2ZnC MAX through a facile gas-phase fluorination strategy and utilized as an efficient protective coating layer for Zn anode. The ionically conductive and hydrophobic ZnF2 inhibits hydrogen evolution reaction and promotes uniform distribution and migration of Zn2+. Meanwhile, the electronically conductive V2CTx effectively homogenizes the electric field and reduces local current density. Consequently, a stable, dendrite-free Zn anode with excellent cycling stability (over 2100 h at 3.0 mA cm−2) is achieved. Furthermore, ZnF2/V2CTx coating layer not only significantly improves the reversibility of zinc deposition/stripping, but efficiently reduces the electrochemical polarization. When paired with a zinc vanadate (Zn2V2O7 and ZnV3O8) cathode derived directly from the gas-phase oxidation of V2ZnC, the full cells exhibit a 1000-cycle lifespan at 5.0 A g−1, and superior rate performance (≈237.6 mAh g−1 at 10.0 A g−1).

This review summarizes recent advancements in the synergistic effects of the electrochemical reduction of CO2 (eCO2RR) to multi-carbon (C2+) products. Starting with the fundamental principles of eCO2RR for C2+ product formation, the paper outlines the reaction mechanisms for producing C2, C3, C4, and C5 products. A comprehensive discussion is provided on the critical impact of synergistic effects on the structure–performance relationship in eCO2RR for the production of C2+ products. Subsequently, the synergistic effects observed are classified in various electrocatalysts with different properties, including single/dual-atom catalysts, multi-centric catalysts, single-atom alloys, metal-organic frameworks, and heterojunction catalysts. Finally, the challenges in achieving selective C2+ product formation in eCO2RR through synergistic effects are discussed, along with corresponding strategies to overcome the obstacles.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"58 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745514","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}

However, achieving superior mechanical properties remains a significant challenge for SA aerogels as engineering materials.

In this study, a highly stable hydrosol with strong antibacterial properties is developed by adsorbing hydrophilic groups of polymer chains onto the Cu-Ag bimetallic nanoparticles (BNPs). The synergistic effects of polyvinylpyrrolidone (PVP) and polyvinyl alcohol (PVA) overcame the incompatibility between the polymer components and nanomaterials, enhancing the dispersion and stability of the Cu-Ag BNP hydrosol. The results demonstrates that the hydrosol exhibited potent antibacterial activities at 50 ppm (w/w), achieving approximately a 5-log reduction for sessile cells after 21 days using retrieved coupons from 3-day pre-culture vials. The hydrosol led to much cleaner X80 coupon surfaces due to biofilm inhibition and MIC mitigation. The weight loss measurements reveals corrosion inhibition efficiencies of 91% and 78% at 50 ppm and 25 ppm, respectively. Additionally, the density functional theory (DFT) modeling reveals that copper regulates silver ion release, enhancing the antibacterial action. While the Cu-Ag BNP hydrosol shows great potential, challenges still exist in scaling its applications, especially in marine and other harsh environmental settings.
