We demonstrate the low-temperature electrochemical synthesis of cubic carbon nitride (c-C3N4) via co-oxidation of carbide (C22−) and nitride (N3−) ions in molten LiCl–KCl at 450 °C. Using CaC2 and Li3N as stable precursors, we investigate the thermodynamic and electrochemical windows for C─N bond formation on nickel and platinum electrodes. Cyclic voltammetry, potentiostatic, and pulsed electrolysis reveal that co-oxidation enables the nucleation of C─N bonded phases, with substrate selection critically influencing phase composition and crystallinity. X-ray diffraction (XRD) revealed reflections consistent with a cubic C3N4 candidate phase on Pt electrodes under pulsed conditions, while scanning electron microscopy/energy-dispersive X-ray spectroscopy, Raman spectroscopy, and nanoindentation supported the formation of a dense carbon nitride-containing layer with hardness values up to 9.56 GPa. These findings show that molten-salt electrochemistry provides a low-temperature route to carbon nitride-containing deposits with XRD reflections consistent with a c‑C3N4 candidate phase at 450 °C, a temperature substantially lower than those required in conventional high-pressure or vapor-phase approaches.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cnma.70337","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149146630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adsorption using an effective adsorbent is highly efficient for remediation of organic dye molecules. In this work, a cost-effective magnetite nanoparticle@zirconium benzenedicarboxylate (Fe3O4/Zr-BDC MOF) nanocomposite was synthesized hydrothermally for the removal of CR. As per our knowledge, the synthesized Fe3O4/Zr-BDC MOF nanocomposite for CR removal has not been reported yet. X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy and energy dispersive X-ray spectroscopy, vibrating sample magnetometry, characterizations were performed to determine material property. The maximum adsorption efficiency of Fe3O4/Zr-BDC MOF was 96% for 20 parts per million (ppm) of CR in 5 min. The reusability of Fe3O4/Zr-BDC MOF was also observed over five successive adsorption cycles. The effect on seed germination assay was performed on Cicer arietinum (black gram) seeds to assess the dye toxicity before and after adsorption. The magnetic and highly porous properties of the synthesized Fe3O4/Zr-BDC MOF nanocomposite make them synergistically more effective and efficient toward the adsorption and removal of CR dye.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149048201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It focuses on how the chalcogen atom in NbX2 affects structural, electronic, and electrochemical properties. Both MoSe2/NbS2 and MoSe2/NbSe2 are energetically stable with low-strain configurations and binding energies of –125.60 and –130.07 meV per unit cell. Both systems exhibit metallic behavior, favorable for charge transport. Sodium adsorption is stronger in MoSe2/NbS2 (–1.83 eV) than in MoSe2/NbSe2 (–1.01 eV). Accordingly, MoSe2/NbS2 shows a higher storage capacity (188 mAh/g) and lower open-circuit voltage (0.35 V) than MoSe2/NbSe2 (106 mAh/g, 0.87 V), both within the desirable range. Simulations confirm thermal stability at 300 K, while CI-NEB results indicate faster Na-ion diffusion in MoSe2/NbS2. The superior performance of MoSe2/NbS2 is attributed to a larger work function difference, generating a stronger interfacial electric field that enhances sodium adsorption and diffusion. Overall, chalcogen selection in NbX2 offers an effective strategy for optimizing 2D heterostructure anodes.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149047950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design strategy leverages a nitrogen-rich tetra-ethynyl imidazole synthon (DIA) and diverse dibrominated polycyclic aromatic hydrocarbons (PAHs) (2–6), enabling efficient heteroatom incorporation and extended π-conjugation. Comprehensive porosity analysis using argon sorption measurements revealed high surface areas of up to 545 m2 g−1 and average pore volumes of 0.33 cm3 g−1. The presence of nitrogen heteroatoms and PAH backbones facilitates strong guest–host interactions, leading to outstanding CO2 uptake of 221 mg g−1 at 273 K under ambient pressure. Remarkably, these materials also demonstrated exceptional iodine vapor adsorption capacities, reaching up to 3.25 g g−1. Furthermore, iCOP1–5 function as highly active heterogeneous catalysts for the cycloaddition of CO2 with styrene oxide, delivering cyclic carbonate (4-phenyl-1,3-dioxolan-2-one) with excellent yields (up to 97%) and selectivity.

However, a clear understanding of its structural nature remains under debate. In this work, the influence of synthesis atmosphere (nitrogen, open air, and vacuum) on the structural, optical, and electrochemical properties of BCNO is systematically investigated. X-ray diffraction and FTIR analyses indicate the coexistence of turbostratic BN and cubic B2O3 phases in all samples, with their relative contributions strongly dependent on the synthesis environment. Photoluminescence studies reveal defect-mediated tunable emission behavior, with nitrogen-related defects dominating the red emission (~650 nm) and oxygen-related centers contributing to the blue emission (~450 nm), while the open-air samples exhibit a broadband emission (400–800 nm) due to overlapping defect states. Mott–Schottky analysis reveals an atmosphere-dependent shift in flat-band potential, enabling estimation of band alignment. Notably, the vacuum-based sample exhibits superior electrochemical performance with an areal capacitance of ~57 mF cm−2, attributed to its defect-rich structure and increased surface sites. These findings support a structure-defect-property relationship and suggest atmospheric control enables tuning of BCNO and provides a rational strategy for its optimization in luminescence and energy storage applications.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148943259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve this goal, a new-type composite film was fabricated via electrospinning and hot pressing treatment. Utilizing the self-polymerization of dopamine under alkaline condition, polydopamine (PDA) was deposited on the surface of boron nitride (BN). The obtained BN@PDA acted as filler for polyvinyl alcohol (PVA). In addition, polyvinylidene fluoride (PVDF) was introduced into PVA through coaxial spinning. The results indicated that the thermal conductive filler was uniformly distributed and well adhered on the fiber. Moreover, thanks to the intermolecular force between PVA and PVDF, the acquired composite film had good thermal stability with the decomposition temperature over 300 °C. On the other hand, the got composite film exhibited good thermal conductivity at low filling ratio. It could quickly transfer the heat generated during the operation of the LED light, which could reduce the operating temperature of the equipment in actual use, demonstrating its good heat dissipation capability.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148878316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
