The accumulation of antibiotic pollutants in aquatic environments poses threats to ecosystems. Photocatalysis is a promising approach for removing these pollutants, but conventional powder photocatalysts often suffer from difficult recovery and poor stability. Therefore, developing efficient, stable, and easily recoverable catalytic materials is important. In this study, 2D g-C 3 N 4 and MoS 2 were immobilized in a polyvinylidene fluoride (PVDF) membrane to prepare a g-C 3 N 4 /MoS 2 /PVDF piezo-photocatalytic composite membrane. Under the combined action of visible light and mechanical vibration, the membrane achieved a TC degradation efficiency of 76.54%, indicating a synergistic enhancement between piezoelectric polarization and photocatalysis. The formation of C─S bonds at the g-C 3 N 4 /MoS 2 interface enhanced electronic coupling between the two phases, promoting directional migration and spatial separation of photogenerated carriers. Meanwhile, the piezoelectric built-in electric field generated by PVDF under ultrasonic excitation further suppressed carrier recombination and accelerated interfacial charge transfer. Overall, the g-C 3 N 4 /MoS 2 /PVDF membrane shows good visible-light response, piezoelectric-assisted charge separation, mass transfer, recyclability, and stability, offering a new approach for antibiotic wastewater treatment and related membrane material design.

Advancing novel photocatalytic systems for efficient antibiotic removal is a key strategy for sustainable water purification. However, it remains technically challenging to balance high charge separation efficiency with broad-spectrum light absorption. Herein, the g-C 3 N 4 /Bi/BiPO 4 composite photocatalyst featuring a Z -scheme heterojunction mediated by Bi nanoparticles was synthesized and systematically evaluated. This unique structure integrates surface plasmon resonance (SPR) to simultaneously enhance charge separation and visible light absorption, addressing limitations of traditional g-C 3 N 4 -based systems. Photoelectrochemical characterization confirmed its superior charge separation and rapid electron transfer. Energy band analyses via UV–Vis DRS, XPS valence, and Mott-Schottky tests revealed that the Z -Scheme heterojunction, formed through an internal electric field and mediated by Bi, effectively enhanced the processes of charge separation and light absorption synchronously. Under simulated solar light irradiation, the composite exhibited a 97.5 % tetracycline degradation rate within 90 min, with a reaction rate constant of 4.00 × 10 −2 min −1 , significantly outperforming individual g-C 3 N 4 and BiPO 4 catalysts. Reactive species trapping experiments identified ·OH, ·O 2 − , 1 O 2 and h + as the dominant reactive species in tetracycline degradation. Overall, this study provides a solid theoretical foundation and experimental support for the practical application of photocatalytic technology in wastewater treatment.

The escalating industrial activities in metal processing, textile manufacturing, petroleum refining, leather production, and pulp industries have generated substantial amounts of industrial wastewater, presenting critical environmental challenges that require immediate attention. In this study, we developed a novel polyacrylonitrile grafted ionic liquid (PAN-g-IL) membrane through γ-ray irradiation-induced grafting of 1-vinyl-3-ethylimidazolium bromide onto polyacrylonitrile, followed by non-solvent induced phase separation (NIPS) membrane fabrication [1] . The developed membrane exhibited exceptional separation performance for both dye-laden and oil-contaminated wastewater systems. The PAN-g-IL membrane demonstrated a pure water flux of 358.1 L m −2 h −1 with remarkable rejection rates exceeding 98% for cationic dyes, and for oil–water emulsions has a very good retention performance [2] , indicating superior antifouling properties and long-term operational stability.

In this work, a nanocrystalline/amorphous graphitic carbon nitride (g-C 3 N 4 ) nano-interlayer was formed in-situ between AlN substrate and Ag film through ultrasonic spraying combined with subsequent heat treatments . The interface mechanical behavior and failure mechanism of the novel AlN/Ag structures with different thicknesses of g-C 3 N 4 nano-layers were investigated using experimental and numerical simulation methods. Following four-point bending test, the debonded surfaces of Ag film and AlN were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results demonstrated that the in-situ-formed g-C 3 N 4 nano-interlayer significantly improved the mechanical properties of the AlN/Ag interface due to the mechanical interlocking effect combined with the strong interfacial bonding strength . The g-C 3 N 4 nano-interlayer effectively relieved stress concentration near the Ag film and delayed the interfacial damage in the AlN/Ag structure, leading to significant improvement in interfacial fracture toughness . The thickness of g-C 3 N 4 nano-layers played a critical role in determining the mechanical performance of the AlN/Ag structure. Specifically, the structure with 90 nm thick g-C 3 N 4 interlayer exhibited the highest critical fracture energy G IC and maximum interfacial peeling stress σ max , with increases of 442 % and 132 %, respectively, compared with that without g-C 3 N 4 .

Tetracycline (TC), a widely used broad-spectrum antibiotic for treating bacterial infections, poses significant risks to human health and ecological environments caused by extensive abuse. Hence, sensitive detection and efficient degradation of TC are crucial for protecting both human health and ecological environment. In this work, a multifunctional Z-scheme Cu 2 O@Ag/g-C 3 N 4 heterojunction was designed and constructed in order to achieve both ultrasensitive surface-enhanced Raman scattering (SERS) detection and efficient photocatalytic degradation of TC. The influence of the Ag content on the SERS performance was investigated using the finite-difference time-domain (FDTD) method. The charge transfer (CT) mechanism was deduced by band gap and Fermi level calculations. The results showed that the synergistic effect of electromagnetic enhancement (EM) and chemical enhancement (CE) contributed to the excellent SERS sensitivity of Cu 2 O@Ag/g-C 3 N 4 nanocomposites (NCs). The limit of detection (LOD) for TC using Cu 2 O@Ag/g-C 3 N 4 NCs as SERS substrate was as low as 10 −12 M, and the SERS substrate could also be used to TC detection in real milk samples. In addition, Cu 2 O@Ag/g-C 3 N 4 NCs could also act as the efficient photocatalyst to achieve the removal of TC with degradation rate of 94 % under visible light irradiation. Especially, the Cu 2 O@Ag/g-C 3 N 4 NCs maintained excellent photocatalytic performance even after six cycles. Possible degradation pathways and photocatalytic degradation mechanism of TC catalyzed by Cu 2 O@Ag/g-C 3 N 4 NCs were also proposed. This multifunctional Z-scheme Cu 2 O@Ag/g-C 3 N 4 NCs should thus have great potential for the integration of ultrasensitive SERS detection and efficient degradation of antibiotics.

Nanocomposites have demonstrated excellent performance as photocatalysts in various photocatalytic reactions. Herein, we developed a nanocomposite comprising modified graphitic carbon nitride (MCN) and gold nanoparticles (Au NPs) for the hydrogen evolution reaction (HER). The MCN was synthesized via co-polymerization of melamine and malonamide. The Au/MCN nanocomposite exhibited hydrogen evolution rates of 86.7 µmol·h − 1 ·g − 1 under visible light and 1281.2 µmol·h − 1 ·g − 1 under simulated sunlight, respectively. The photocatalytic HER rate of Au/MCN under simulated sunlight was enhanced by a factor of 99.3 compared to pristine g-C 3 N 4 nanosheet (CN). Controlled hydrogen evolution experiments confirmed the contribution of the surface plasmon resonance (SPR) effect. By combining HER results with conventional characterization and electrochemical tests, we elucidated the photocatalytic mechanism, revealing that the Schottky junction and SPR effect synergistically enhance the photocatalytic performance. The SPR effect was further verified by photocatalytic experiments and ultraviolet-visible diffuse reflectance spectroscopy.

Circularly polarized luminescence (CPL) materials, which exhibit their unique chiroptical properties, display great potential for applications in optoelectronics and bioimaging. However, it remains a significant challenge to synthesize CPL materials with high dissymmetry factors (g lum ) and photoluminescence quantum yields (PLQY) simultaneously. Herein, we report a deep-eutectic-solvent (DES)-assisted self-assembly protocol integrated with an active-learning (AL) framework that enables the targeted fabrication of G-quadruplex (G4) supramolecular gels with high g lum and PLQY. AL pinpointed the optimal synthesis parameters in just four iterations, dramatically accelerating material development. The top-performing gel achieved a g lum of 0.29, setting a new benchmark for nucleoside/nucleotide-based CPL materials. The maximum PLQY reached 10.64%, which represents a substantial level of performance. Furthermore, by integrating SHapley Additive exPlanations (SHAP), we elucidated the relationship between reaction parameters and target properties. Building on this result, we also demonstrated multicolor fluorescence resonance energy transfer (FRET) by incorporating dyes, successfully developing a series of multicolor CPL-active materials. This work not only provides new insights into the design of bio-based chiral CPL materials but also highlights the promising role of artificial intelligence in advancing material development.

Ternary g-C 3 N 4 /Ti 3 C 2 T x /MIL-101(Fe) photocatalyst was constructed via in situ assembly. • Ti 3 C 2 T x promotes interfacial charge separation and accelerates electron transfer. • Rapid in situ H 2 O 2 generation enables an oxidant-free visible-light photo-Fenton process. • CTF achieves efficient, broad-spectrum degradation of dyes and PPCPs. Visible-light photo-Fenton oxidation represents a promising strategy for removing dyes and pharmaceuticals/personal care products (PPCPs), which are persistent water contaminants. However, its broader application is constrained by challenges such as inefficient charge separation and dependence on externally added hydrogen peroxide (H 2 O 2 ). In this study, a ternary g-C 3 N 4 /Ti 3 C 2 T x /MIL-101(Fe) photocatalyst was synthesized via the in-situ growth of MIL-101(Fe) on g-C 3 N 4 /Ti 3 C 2 T x , enabling efficient visible-light-driven, zero-external H 2 O 2 -added photo-Fenton degradation of organic pollutants. The hybrid system exhibits significantly enhanced oxygen activation and interfacial electron-transfer capability, with in situ H 2 O 2 generation rates about three times higher than those of pristine g-C 3 N 4 . Under visible-light irradiation, the composite continuously produces reactive oxygen species ( ∙ O 2 - , and ∙ OH) at substantially higher levels than g-C 3 N 4 and g-C 3 N 4 /MIL-101(Fe), indicating promoted charge separation and faster interfacial electron transfer. As a result, the catalyst enables broad-spectrum pollutant removal within 60 min, achieving degradation efficiencies of 99.78% (methylene blue), 99.49% (rhodamine B), 88.27% (tribromophenol), 61.50% (doxycycline hydrochloride), and 78.98% (levofloxacin). Overall, rapid in situ H 2 O 2 formation, coupled with efficient ROS generation, enables high-performance pollutant degradation without the need for external oxidant dosing, providing a green strategy for degrading dyes and PPCPs under visible light.

With the rapid development of global industrialization, demand for oil-water separation materials that can handle complex scenarios is increasing. Herein, a multifunctional bacterial cellulose (BC) derived g-C 3 N 4 /C composite aerogel for oil-water separation is proposed through a novel simultaneous fabrication process of converting raw BC membranes into carbon aerogels, doping N element into carbon skeletons and realizing in situ deposition of g-C 3 N 4 . The resultant g-C 3 N 4 /C composite aerogel integrates large absorption capacity, flame retardancy, antibacterial activity, hyperelasticity and wide operating temperature. The BC-derived g-C 3 N 4 /C composite aerogel exhibits a maximum adsorptive capacity of 188 g/g for dichloroethane and 73 g/g for n-hexane, much larger than the reported range of 65–135 g/g. Gravity-driven oil-water separation results demonstrate fluxes of 2818.4 L·m −2 ·h −1 for n-hexane and 2000 L·m −2 ·h −1 for ethyl acetate. Ten adsorption-combustion cyclic tests indicate combustion of organic solvents does not compromise adsorption performances, with n-hexane capacity retaining 97.6% of the initial value. Simultaneously, the composite aerogel shows an antibacterial rate as high as 96.3%. In addition, hyperelasticity is exhibited, with merely 0.75% irreversible deformation after 10,000 compression cycles. This effective strategy is expected to provide more possibilities for oil-water separation applications.

Photocatalytic plastic reforming for H 2 production offers a promising eco-friendly strategy for waste resource upcycling, yet constructing efficient single-atom photocatalysts remains a challenge. Herein, we report a support doping strategy to tailor the coordination environment of single atoms, and develop a single-atom Pt decorated P-doped g-C 3 N 4 photocatalyst (Pt 1 /PCN). The Pt 1 /PCN featuring an asymmetric Pt N 3 structure exhibits a H 2 production rate of 2722.8 μmol g −1 h −1 , which is 17.3 times that of Pt/CN and 7.8 times that of Pt 1 /CN, and outperforms previously reported CN-based photocatalysts. Mechanistic studies indicate that the asymmetric Pt N 3 configuration enhances the internal electric field, effectively facilitating the separation of photogenerated charges. Meanwhile, the doped P atoms serve as electron donors to alleviate the electron deficiency of Pt sites, promoting the upward shift of the d-band center of Pt, thereby optimizing the reaction kinetics for H 2 evolution. More importantly, the practical applicability of Pt 1 /PCN is demonstrated by its excellent performance in outdoor photocatalytic plastic reforming for H 2 production. This work presents a rational design strategy for the construction of efficient single-atom photocatalysts and provides in-depth insights into the atomic-level mechanism of H 2 evolution.

The G protein-coupled estrogen receptor (GPER), widely expressed across human tissues, modulates key physiological processes and associated signaling pathways. Bisphenol A (BPA), a global high-production-volume chemicals, finds extensive use in diverse industrial applications. In this study, we employed an integrated approach of multispectral analysis and molecular simulations to systematically investigate the interaction mechanisms between GPER and bisphenol compounds (BPs), with BPA as a representative. Molecular docking predicted stable binding of BPs within the active pocket of GPER. Solvent-accessible surface area (SASA) analysis revealed an increase in both hydrophobic and hydrophilic surfaces upon BPs binding, indicative of alterations in the protein's microenvironment. Fourier transform infrared (FT-IR) spectroscopy further confirmed that BPs binding induces rearrangement in the secondary structure of GPER. Molecular dynamics simulations revealed an overall structural contraction of GPER upon ligand binding, a conformational change independently corroborated by three-dimensional fluorescence spectroscopy. Energy transfer distance measurements yielded binding distances ranging 2.20 from and 2.80 nm. Notably, the more compact BPF showed the closest proximity, whereas the flexible-chain analog BPE exhibited the farthest, underscoring how substituent structure dictates binding localization. Thermodynamic analysis highlighted the significant roles of hydrogen bonding and hydrophobic interactions. Complementarily, Molecular Mechanics/Poisson-Boltzmann Surface Area (MM-PBSA) and interaction region indication (IRI) analyses pinpointed van der Waals forces as a major contributor to complex stability. Collectively, our integrated findings decipher the molecular-level interaction mechanism between BPs and GPER. This work provides a theoretical foundation for assessing the endocrine-disrupting potential of bisphenol compounds and aids in the rational design of safer alternatives.

The ubiquitous application of highly flammable acrylonitrile–butadienestyrene (ABS) resin has brought great fire threat to human and environment. Unfortunately, current flame retardants often improve flame retardancy but reduce mechanical and thermal properties, seriously affecting their practical application. We herein reported novel multifunctional, high-efficiency, phosphorus and nickel co-doped graphitic carbon nitride (Ni-P-C 3 N 4 ) nanoflakes to address the trade-off between flame retardancy and mechanical/thermal properties. The addition of 2.0wt% of Ni-P-C 3 N 4 increased the initial degradation temperature and tensile strength of ABS composite (ABS/Ni-P-CN2) by 15 °C and 24.3% relative to virgin ABS, indicating its positive effect on thermal and mechanical properties. Compared with ABS, ABS/Ni-P-CN2 exhibited a notable increase in time to ignition, along with 32.4% and 33.8% reductions in peak heat release rate (PHRR) and peak smoke production rate (PSPR), demonstrating excellent anti-ignition, flame-retardant and smoke-suppressive performances. The increased fire safety was mainly due to the physical barrier effect of g-C 3 N 4 nanosheets and the catalytic charring effect of P and Ni. This work offers a novel design strategy to create multifunctional flame retardants for fabricating fire-safe polymer composites with superior thermal and mechanical properties, holding great potential in industries.
