Atomically thin two-dimensional (2D) carbon nitride sheets (CNs) are attracting attention in the field of photocatalytic CO2 reduction. Because rapid recombination photogenerated electron–hole pairs and limited more active sites, efficiency CNs cannot meet actual requirements. Here, atomically 2D/2D van der Waals heterostructures metal-free graphdiyne (GDY)/CNs fabricated through a simple electrostatic self-assembly method. Experimental characterizations along with first-principles...
Wide-band vibration is abundant in various industrial equipment, but extracting low frequency energy challenging. Here, we demonstrated a trapezoidal cantilever-structure triboelectric nanogenerator (C-TENG) that can efficiently harvest from the range of 1-22 Hz. The C-TENG fabricated with flexible film electrode, and its mechanical model analyzed structural mechanics for optimal performance device. source as 1 Hz, output power density reaches 62.2 W/m3 at 5 Furthermore, management module...
Symmetry lies at the heart of two-dimensional (2D) bioelectronics, determining material properties fundamental level. Breaking symmetry allows emergent functionalities and effects. However, modulation in 2D bioelectronics resultant applications have been largely overlooked. Here, we devise an oxidized architectural MXene, referred to as MXene (OXene), that couples orbit symmetric breaking with inverse entitle optimized interfacial impedance Schottky-induced piezoelectric The resulting OXene...
Nitrogen doping is a promising approach to induce the basal-plane localized magnetic moments in $\mathit{sp}$-electron-only graphene sheets. Enhancing couplings among can contribute high Curie temperature ${T}_{C}$ and large ratio of ferromagnetism (FM), which vital for real applications spintronic devices; however, it still challenging. Here, we experimentally demonstrate that graphitic nitrogen (N-Q) could enhance ferromagnetic provided by defective N nitrogen-doped (NG). Nearly pure FM at...
The low separation efficiency of the photogenerated carrier and poor activity surface redox reaction are main barrier to further improvement photocatalytic materials. To address these issues, introducing spin‐polarized electrons in single‐component materials emerged as a promising approach. However, decreased ability photocarriers becomes new challenge. Herein, we mitigate this challenge with carbon nitride sheet (CNs)/graphene nanoribbon (GNR) composite material that has van der Waals...
Fluorination can significantly change the physical and chemical properties of carbon materials (CMs). Common sense for fluorination mechanism CMs indicates that one basal-plane C–F group (CF group) form as fluorine atom bonded to along out-of-plane networks without creating edge groups (including CF2 CF3 groups) at vacancies in networks. We report generally create multidimensional such graphite, graphene, nanotubes, fullerene, concentration is dependent on both crystallinity starting...
Spintronic devices are regarded as prime candidates for addressing the demands of emergent applications such in-memory computing and Internet Things, characterized by requirements high speed, low energy consumption, elevated storage density. Among these, spin valves, serving fundamental structures magnetic random-access memory, have garnered substantial attention in recent years. This study introduces an all van der Waals (vdW) heterostructure composed Fe3GeTe2 (FGT)/tellurene/FGT, wherein a...
Although graphitic carbon nitride nanosheets (CNs) with atomic thickness are considered as promising materials for hydrogen production, the wide band gap (3.06 eV) and rapid recombination of photogenerated electron–hole pairs impede their applications. To address above challenges, we synergized atomically thin CNs graphene quantum dots (GQDs), which were fabricated 2D/0D Van der Waals heterojunctions, H2 generation in this study. The experimental characterizations indicated that addition...
Atomically thin two-dimensional (2D) CN sheets have attracted extensive attention in the field of photocatalysis because their shorter diffusion path photogenerated carriers and abundant surface reaction sites than bulk CN. However, 2D CNs still exhibit poor visible-light photocatalytic activity a strong quantum size effect. Here, PCN-222/CNs vdWHs were successfully constructed using electrostatic self-assembly method. The results showed that with 1 wt.% PCN-222 enhanced absorption range...
Fluorescent tremella-like carbon nanosheets (TCNs) were hydrothermally synthesized using citric acid and adenosine as the starting materials. The resulting product had high quantum yield, water-solubility, photostability. addition of 2,4,6-trinitrophenol (TNP) induces remarkable fluorescence quenching, this phenomenon was used to construct a TNP sensor. quenching TCNs by shown be likely due inner filter effect. developed sensor has wide linear range from 0.05 50.0 μM with detection limit 5...
