Here, we report a dielectric-barrier-assisted criss-cross electrode configuration for solution plasma (SP) synthesis that achieves stable, low-temperature glow discharge in a benzene–DMF mixture. Finite-element simulations and optical diagnostics reveal that the dielectric barrier suppresses electron avalanches, producing a spatially uniform CN-rich plasma (∼2505 K) while minimizing C<sub>2</sub> formation, thereby preserving aromatic integrity and limiting nitrogen loss. Compared to the conventional pin-to-pin SP, which generates high-temperature (∼5280 K), C<sub>2</sub>-dominated abnormal glow, the dielectric-stabilized system yields few-layer NG with markedly reduced defect density (I<sub>D</sub>/I<sub>G</sub> = 0.133), narrower 2D band (FWHM = 70 cm<sup>−1</sup>), and higher crystallinity. XPS analysis shows a nitrogen content of 12.22 at% with a high fraction of quaternary N (32.6 %), achieved without detectable metal carbide impurities. Mechanistic analysis suggests that the CN-rich plasma environment promotes polymerization of nitrogen-containing oligomers (e.g., CN·, C<sub>6</sub>H<sub>5</sub>·) into ordered graphene frameworks, providing a controllable pathway for tailoring both the structural and chemical properties of NG. Additional precursor tests (σ-bonded aliphatic, π-bonded aromatic, and extended conjugated molecules) further confirm the generality of this CN-driven mechanism. This work establishes a scalable, low-temperature, in-liquid plasma strategy for producing high-purity, nitrogen-rich graphene with tunable functionalities.</div></div>","PeriodicalId":262,"journal":{"name":"Carbon","volume":"246 ","pages":"Article 120914"},"PeriodicalIF":11.6,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145218166","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}

By combining the axial anisotropy of 1D materials with the in-plane characteristics of 2D materials, such architectures offer broad application prospects in areas such as out-of-plane electrical conduction and 3D thermal diffusion. In this study, a 3D chemically bonded heterostructure comprising vertically aligned carbon nanotubes (VA-CNTs) and defect-free graphite was synthesized via optimized Al<sub>2</sub>O<sub>3</sub>/Fe/graphite catalytic system, forming a 3D VA-CNTs/graphite allotropic heterostructure without an intermediate dielectric layer. Experiments have proved that the presence of amorphous Al<sub>2</sub>O<sub>3</sub> effectively confines lateral migration of Fe nanoparticles and suppresses their ripening, thereby reducing the size dispersion of the catalyst particles, ultimately facilitating an ordered growth of VA-CNTs. Furthermore, this confinement mechanism shows its applicability to other 2D materials like h-BN, which broadens its potential applications. This reveals a new way of developing novel anisotropic 3D nanostructures based on hierarchical CNT grafting, allowing the utilization of the intrinsic properties of both nanomaterials, with potential applications in various fields.</div></div>","PeriodicalId":262,"journal":{"name":"Carbon","volume":"246 ","pages":"Article 120908"},"PeriodicalIF":11.6,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145218232","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}
