A facile thermal polymerization was applied to synthesize carbon and oxygen dual-doped graphitic carbon nitride (MACN) with controllable electronic band structure using malonic acid and urea as precursors. The C and O atoms substituted the sp 2 N atom in graphitic carbon nitride (CN). The 1MACN (1 represented that the weight ratio of malonic acid to urea is 1% during the synthesis) with optimal band structure could decompose 15 ppm bisphenol A (BPA) within 150 min, and the mineralization rate reached to 52%. The superior photocatalytic performance of 1MACN was mainly ascribed to electronic band structure together with optical properties . On the one hand, the formation of delocalized big π bonds favored the electrons transfer after the introducing of carbon atoms. On the other hand, a positive charge density existed on the C atoms because of high electronegativity of contiguous O (3.44) that substituted N compared with C (2.55), which could attribute to high activity of MACN catalyst. The study will contribute to the further improvement of visible-light photocatalytic BPA degradation and mineralization.

A narrow-band green-emitting phosphor KAl 11 O 17 (KAO): Eu 2+ , Mn 2+ , was synthesized via a high-temperature solid-state reaction to evaluate its potential for use in high-quality backlight displays. Structural refinement reveals that Eu 2+ and Mn 2+ ions preferentially occupy distinct crystallographic sites: Eu 2+ resides at K + sites in the conductive layer, whereas Mn 2+ substitutes for tetrahedral Al 3+ sites within the spinel block. This spatial separation facilitates efficient energy transfer (ET) from Eu 2+ to Mn 2+ . Spectroscopic analysis of the optimally doped composition, KAO: 0.07Eu 2+ , 0.04Mn 2+ , indicates that the ET proceeds predominantly via a dipole - quadrupole ( d - q ) mechanism. The resulting phosphor exhibits bright green emission centered at 510 nm with an exceptionally narrow full width at half maximum (FWHM) of 8.13 nm, a high color purity of 98%, and an internal quantum efficiency (IQE) of 65.41%. Moreover, the material demonstrates excellent thermal stability, retaining 93.11% of its initial luminescence intensity at 423 K, corresponding to a thermal activation energy of 0.2917 eV. To demonstrate its practical utility, a white LED device was fabricated by combining the optimized green phosphor (KAO: 0.07Eu 2+ , 0.04Mn 2+ ) with a blue phosphor (BaMgAl 10 O 17 (BAM): Eu 2+ ), a red phosphor (Ca 9 KMn(PO 4 ) 7 : Eu 2+ ), and a 365 nm near-ultraviolet chip. The resulting device achieves a wide color-gamut covering 107.8% of the NTSC standard. Collectively, these results demonstrate that precise control of site occupancy and energy transfer enables the design of green phosphors that simultaneously exhibit narrow-band emission, high color purity, and robust thermal stability-properties that are essential for wide color-gamut WLED backlight displays.

Visible-light-driven photocatalysis offers a sustainable strategy to eliminate indoor volatile organic compounds (VOCs) like acetaldehyde (AA), thereby improving indoor air quality. Although heterojunctions based on MoS 2 quantum dots (MQDs) attract attention for oxidation reactions, MQDs/WO 3 composites for VOC removal remain largely underexplored. In this study, MQDs/WO 3 heterojunctions were constructed by coupling MQDs with monoclinic (m-WO 3 ) and hexagonal (h-WO 3 ) phases to systematically investigate phase-dependent charge transfer, reactive oxygen species (ROS) generation, and AA degradation pathways. Comprehensive characterizations indicated that MQDs incorporation increased oxygen vacancies, promoted ROS generation, and enhanced visible-light absorption. Furthermore, PL and in situ DRIFTS analyses revealed that MQDs/m-WO 3 exhibited superior electron-hole separation and stronger surface reactivity than the h-WO 3 system. DFT calculations confirmed MQDs as the primary adsorption sites for indoor VOCs, with MQDs/m-WO 3 exhibiting stronger AA adsorption. Consequently, the optimized 0.5MQDs/m-WO 3 demonstrated enhanced AA degradation and mineralization under visible light, exhibiting excellent stability under indoor-relevant operating conditions. This work provides profound insights into interface-regulated charge transfer and offers a promising material design strategy for advanced indoor air purification.

An S-scheme Ag/CdS/Fe 2 O 3 (Ag/CS/FO) heterojunction was fabricated via a sequential solvothermal and photodeposition method. The microstructure and optoelectronic properties of the synthesized ternary composite were verified by a series of characterization methods. The transfer of photogenerated electron–hole pairs (e − /h + pairs) follows an S-scheme pathway, driven synergistically by the interfacial electric field (IEF) and band bending. That directs electrons (e − ) to the conduction band (CB) of CdS (CS) and holes (h + ) to the valence band (VB) of Fe 2 O 3 (FO), achieving efficient e − /h + pairs separation while maintaining high redox capabilities. Additionally, the incorporated Ag nanoparticles enhance visible-light harvesting via the surface plasmon resonance (SPR) effect and function as electron-transfer bridges, collectively promoting charge migration. Consequently, the composite exhibits high photocatalytic activity, degrading 98.68% of amoxicillin (AMX) under visible light. It also maintains 91.6% efficiency after four cycles, confirming sound stability. Notably, the material demonstrates superior performance in real-life water matrices (tap and river water), highlighting its strong application potential. Graphical abstract

Inorganic photochromic materials (IPCs) with luminescent modulation show promising potentials in anti-counterfeiting and biological imaging. However, existing IPCs can only be effectively activated by high-energy ultraviolet (UV)/visible (Vis) light or potentially risky x-ray irradiation, often suffering from severe photobleaching, photodamage, and low penetration. Herein, we present a universal strategy to generate near-infrared light-driven trap filling and luminescent modulation behaviors in IPCs, via the energy transfer upconversion (ETU) design. Upon 980 nm irradiation, the synthesized NaNbO 3 :Er 3+ /Yb 3+ displays large luminescent modulation ratio (Δ R t > 80%) and fast response speed to NIR light (10 s, 92%), comparable to or better than those of UV/Vis light irradiation. The designed components exhibit deep-tissue penetrable luminescent imaging, which is unable to be achieved for existing IPCs. The upconversion-mediated strategy is quite robust, and can be extended to other systems, by leveraging the ETU process of up-converting ion pairs (Ln 3+ /Yb 3+ ) to fill the traps and trigger photochromic reaction. Subsequently, the excited state energy of activators is captured by trap centers via a fluorescent resonance energy transfer (FRET), then resulting in luminescent modulation. This work sheds new light on designing NIR light-driven IPCs, and will contribute substantially to high-level optical storage and biological applications.

High-power white light sources are highly desirable in laser lighting and the emerging visible light communications (VLCs) for next-generation 6G wireless system; however, the advance is restricted by deficient and inefficient emitters. Here, we develop a wafer-scale, Ce 3+ -doped, garnet-type, quasi-transparent ceramic as yellow emitters through a mild stepped crystallization in aluminosilicate glasses. We elaborate that the densified crystallization process originates from the tailored crystallization energy barrier and the release of ion migration channels during the transformation of the amorphous glass to fully crystallized ceramics. The quasi-transparent, ceramic-based, laser-driven white light photonic engine generates a luminous efficacy of 202 lm W −1 and further supports outdoor VLC over 1.2-kilometer distances, with a peak bandwidth of up to 71.8 MHz. The full crystallization strategy from glass to quasi-transparent ceramic catalyzes the innovation of transparent luminescent mediums, and the photonic engine lays the foundation for the integration of laser lighting and future VLCs.

The development of efficient and stable visible-light-driven Z-scheme systems for overall water splitting was crucial for solar hydrogen production. However, performance was often limited by photocorrosion of sulfide-based hydrogen evolution photocatalysts and competing, deactivating side reactions involving the redox shuttle. Herein, we construct a robust Z-scheme system by employing a CoP-modified Ni-doped Zn 0.5 Cd 0.5 S heterojunction with strong interfacial interaction as the HEP, coupled with BiVO 4 as the oxygen evolution photocatalyst. The optimized system exhibited an apparent quantum yield of 4.06% at 420 nm and enabled sustained co-evolution of hydrogen and oxygen at a near-stoichiometric ratio. It also demonstrated outstanding cycling stability. Crucially, it had been demonstrated that the regulation of the internal polarizability of HEP effectively suppressed the competitive reduction of the redox medium and the formation of passivated Prussian blue derivatives on the catalyst surface. This work provides fundamental insights into mitigating the side effects caused by fusion through polarizability regulation.

Novel benzyl alcohol-based DESs enable efficient methylnaphthalene separation from LCO. • Multi-stage extraction outperforms high solvent ratio for achieving high removal rates. • Synergistic O-H…π, Cl − /Br − …π, C-H…π interactions underpin the high extraction selectivity. In this study, novel benzyl alcohol (BnOH)-based deep eutectic solvents (DESs) were designed and, for the first time, applied to extract 1-methylnaphthalene from n-dodecane as a light cycle oil (LCO) model system. Liquid-liquid extraction experiments, optimization of operating parameters, quantum-chemical calculations, and molecular dynamics simulations were systematically conducted to evaluate the separation performance and elucidate the underlying mechanism. The results show that TEMAC/BnOH (1:3) exhibited the highest extraction efficiency among the investigated DESs, with a single-stage extraction efficiency exceeding 60% and a cumulative 1-methylnaphthalene removal efficiency of over 90% after four stages of extraction. Increasing the extraction stages is more effective than merely increasing the solvent-to-feed mass ratio. The separation mechanism demonstrates that the high selectivity originates from three synergistic interactions, including the O-H…πbond between the hydroxyl group in BnOH and the aromatic ring, the Cl − /Br − …π interaction, and the methyl-induced C-H…π interaction in the quaternary ammonium salt.

Cuprous (Cu(I)) halide clusters have garnered significant attention for light-emitting devices (LEDs) due to their high photoluminescence quantum yields and broadband emission, both originating from self-trapped excitons. However, their practical implementation is impeded by poor solution processability and challenges in fabricating high-quality films. Herein, we report a facile, scalable mechanochemical synthesis of highly luminescent Cu(I) halide clusters via direct ball milling under ambient conditions. Notably, the incorporation of sodium iodide enhances the dispersibility and solution processability of these clusters without deteriorating their emission properties, enabling the preparation of stable colloidal dispersions and the one-step solution deposition of smooth, uniform films. The resultant electroluminescent devices achieve a peak external quantum efficiency of 5.9% and exhibit uniform yellow emission over a large area of 5 × 5 cm 2 . Through judicious selection of charge-transport layers, we further demonstrate broadband white electroluminescence with voltage-tunable color temperature. Our strategy provides a practical pathway to efficient, scalable, and low-toxicity Cu(I) halide cluster LEDs, while offering key design principles for developing high-performance solution-processable emissive materials in next-generation solid-state lighting.

The development of efficient and economical photocatalysts is the focus of achieving sustainable remediation of water pollution. However, slow photogenerated carrier transfer and insufficient catalytic sites are the main reasons affecting photocatalytic applications. Herein, we developed flake-octahedral BiOBr/MIL-101(Fe) heterojunction catalysts through a facile solvothermal strategy for the degradation of pollutants under visible light irradiation. Scanning electron microscope, X-ray photoelectron spectrometer, Fourier infrared spectrometer, and X-ray diffraction analysis characterizations proved the successful synthesis of flake-octahedral BiOBr/MIL-101(Fe) heterojunction. Absorption spectra and Brunauer–Emmett–Teller analyses showed that the BiOBr/MIL-101(Fe) composites with an atomic percentage of Fe of 9.1 (denoted as BiOBr/MIL III ) had the optimal light absorption and the largest specific surface area. The BiOBr/MIL III achieved a remarkable Rhodamine B (Rh B) degradation efficiency of 94.5% within 60 min, with an apparent rate constant ( k ) of 0.03540 min −1 , demonstrating excellent visible light-driven photocatalytic activity. Photocatalytic mechanistic studies showed that the solvothermal-induced flake-octahedral BiOBr/MIL-101(Fe) III heterojunction promotes the formation of Z-scheme, which significantly enhances the carrier separation efficiency and accelerates the rapid generation of reactive radicals · O 2 − and h + . This work provides a feasible strategy for the construction of flake-octahedral inorganic-MIL photocatalysts with excellent photocatalytic performance.

A concentrated-light driven monolithic PEI/Ni/ γ -Al 2 O 3 offers mechanical robustness, humidity tolerance and enhanced heat and mass transfer for DAC. • DAC desorption completes within 2 min at 70 °C with a CO 2 desorption enthalpy of 45.9 kJ/mol, showing competitive regeneration performance. • Humidity switches the CO 2 capture pathway from carbamate to bicarbonate, achieving 2.35 mmol/g uptake and stable cycling over 18 cycles. The practical deployment of direct air capture (DAC) is hindered by insufficient mass and heat transfer, along with high energy consumption during regeneration, which are intrinsic drawbacks of conventional powdered amine adsorbents. To mitigate these bottlenecks, this work constructs a concentrated-light driven DAC system using a monolithic PEI/Ni/ γ -Al 2 O 3 adsorbents. The monolithic architecture offers a combination of mechanical robustness, humidity tolerance, and enhanced mass and heat transport. The optimized monolith exhibits a CO 2 adsorption capacity of 2.35 mmol/g from 420 ppm CO 2 in air, with an amine efficiency of 0.31 mol CO 2 /mol amine and a regeneration efficiency of 96.92% ± 1.49%. Notably, concentrated light enables complete adsorbent desorption within 2 min at a moderate temperature of 70 °C, and the intrinsic CO 2 desorption enthalpy is 45.9 kJ/mol. Moreover, in-situ FT-IR and DFT calculations reveal two distinct reaction mechanisms under dry and humid conditions, where humidity redirects the reaction pathway from the carbamate route to the stronger-bonded bicarbonate mechanism, driven by efficient electron transfer within water-mediated hydrogen-bonded networks. After 18 consecutive adsorption-desorption cycles, the PEI/Ni/ γ -Al 2 O 3 monolith maintains a steady CO 2 capacity of 1.94 mmol/g, verifying its cycling stability. This study offers a promising strategy for concentrated-light driven DAC, which could provide insights for further development of negative carbon emission techniques. Figure caption.

Recent advances in 4D printing have enabled the development of smart materials with programmable shapechanging capabilities. However, the concurrent realization of sustainability, reprocessability, and multifunctionality remains a key challenge. In this study, a bio-based hybrid vitrimer resin is developed for Digital Light Processing (DLP) 4D printing, utilizing acrylate and epoxy monomers derived from soybean oil. This dual-curable resin allows for compositional tuning, enabling precise control over mechanical, thermal, and rheological properties. The printed structures exhibit excellent shape memory and reconfiguration behavior, along with high printing resolution and surface fidelity. Importantly, the vitrimer network supports closed-loop recycling through dynamic covalent bond exchange, allowing for repair, reprocessing, and reprinting without loss of structural or functional performance. By integrating environmental sustainability, structural versatility, and reusability into a single system, this work demonstrates the potential of bio-based vitrimers as next-generation intelligent materials for sustainable 4D printing and advanced additive manufacturing technologies.
