Fenton-like oxidation is often hampered by high energy barriers, uncontrolled oxidation pathways, and inefficient reactive oxygen species (ROS) utilization. Here, we report an energy-driven confined catalytic nanoreactor that leverages the in-situ confinement energy generated within nanopores to fundamentally regulate degradation thermodynamics. Taking sulfamethoxazole (SMX) as a model contaminant, the confined nanoreactor exhibited a 22.11-fold higher kinetic constant (0.157 min −1 ) and 40 % enhanced mineralization efficiency compared with its non-confined system. The imprinting channel of confined nanoreactor enabled selective adsorption of SMX within the nanochannel, inducing pronounced confinement effects. The resulting confinement energy triggered a low-entropy degradation pathway (ΔS reduced by 3.2 × 10 3 -fold), which broke thermal equilibrium constraints and redirected SMX oxidation along a low-energy-barrier route. The in-situ confinement-induced low-entropy reaction not only accelerated pollutant degradation but also improved ROS conversion efficiency. This study demonstrated a green and sustainable approach to overcome the intrinsic efficiency bottleneck of Fenton-like processes and provide a new perspective on exploiting nanoconfinement effects for environmental remediation.

The activation of the lattice oxygen oxidation mechanism is vital for enhancing oxygen evolution reaction (OER) performance as it enables direct O–O bond formation, avoiding the *OOH formation. Compared with the conventional adsorbate evolution mechanism (AEM), the lattice oxygen-mediated mechanism (LOM) can break the theoretical limit of conventional adsorbate-based scaling relations and enhance the oxygen evolution reaction kinetics. Thus, there is an urgent need for an efficient strategy for designing OER electrocatalysts based on LOM. The O p band center is employed as descriptor in conjunction with machine learning to facilitate the activation of lattice oxygen. The descriptor can accelerate the catalyst design process as it circumvents the need for complex intermediate calculations. According to predictions, the Fe-Co 3 O 4 catalyst exhibits OER performance comparable to that of noble metal catalysts. The Fe-Co 3 O 4 catalyst achieves a low overpotential of 258 mV at 20 mA cm -2 in 0.5 M H 2 SO 4 , attributed to the shift in catalytic mechanism from AEM to LOM.The incorporation of Fe effectively induces an upshift in the O p band center and weakens the Co–O bond, thereby promoting direct O–O coupling for O 2 generation and consequently reducing the OER overpotential. Our study introduces a method to activate the lattice oxygen of metal oxide electrocatalysts, holding substantial promise for enhancing large-scale hydrogen production.

The production of biodiesel from renewable feedstocks through energy-efficient processes remains a pressing challenge. Pickering emulsions, stabilized by solid particles, have emerged as a promising approach to enhance biodiesel production. This study presents the synthesis of dumbbell-shaped Janus polymer nanoparticles (DS-JPNs) functionalized with organic amine bases, which serves as Pickering interfacial catalysts (PICs) for transesterification reaction. The anisotropic morphology and amphiphilic nature of DS-JPNs promote stable adsorption at the soybean oil-methanol interface, leading to reduced interfacial tension, smaller droplet formation, and the generation of thermodynamically stable emulsions. This microreactor system prominently enhances the interfacial area and mass transfer efficiency, thereby accelerating the transesterification efficiency. Consequently, the DS-JPN-TMA catalyst achieved a biodiesel yield of 85.4 % under static conditions, a 2.6-fold increase compared to the spherical PS-TMA counterpart (34.2 %). Among the examined Janus organic base catalysts, DS-JPN-TBD demonstrated the highest catalytic performance (TOF 12.51 h −1 ), attaining a biodiesel yield of 96.7 %, attributable to the strong basicity of its bicyclic guanidine moieties. Furthermore, DS-JPN-TBD retained 94.2 % of its catalytic activity after five reaction cycles, evidencing excellent reusability and durability. This study underscores DS-JPN-TBD as an innovative, energy-efficient, and sustainable solution for biodiesel production and proposes a scalable strategy for green energy applications.

As the demand for sustainable energy continues to rise, the development of high-efficient hydrogen (H 2 ) production via water electrolysis based on precise bubble manipulation is garnering significant attention. This study presents a novel three-dimensional (3D) micro-cone engineered electrode to enhance the ion exchange rate and catalytic active site regeneration during the electrochemical water splitting process, thereby improving H 2 production rates. The unique micro-cones enables precise manipulation of H 2 bubble behavior, which achieves directional transport from nucleation to detachment at the top within a mere 224 ms. Simultaneously, the bubble manipulation performance of micro-cones with varying geometric configurations and dimensional parameters is investigated. The optimal bubble manipulation performance is achieved when the micro-cones have a circular base with a diameter of 100 μm, a height of 300 μm, and an array center distance of 100 μm. The performance of the 3D micro-cone engineered electrode outperforms conventional commercial electrodes, with its capacitance ( C dl ) value reaching 35.1 mF cm −2 , which is significantly higher than those of Ni foam and Ni-CP. Additionally, under a 1.7 V vs. RHE condition, the electrode achieves a current density of 80 mA cm −2 , with a H 2 collection rate 32.3 % higher than that of a Ni foam under identical conditions. Large-scale outdoor experiments driven by solar energy further confirm the scalability and stability of the micro-cone engineered electrodes, which is capable of producing substantial H 2 quantities over extended periods without bubbles blockage. The large-area micro-cone electrodes, when operated continuously under high outdoor current density, still exhibit excellent H 2 production and bubble directional manipulation stability. This research highlights the transformative impacts of advanced electrode design on water electrolysis efficiency and H 2 bubbles manipulation, offering new insights for ultra-high efficient sustainable H 2 production.

Releasing residual stress and reducing interface defects are crucial approaches for improving the photoelectric conversion efficiency and performance stability of perovskite solar cells (PSCs). This research introduces nickel chloride (NiCl 2 ) into the electron transport layer of tin dioxide (SnO 2 ) and applies it to the buried interface of all-inorganic CsPbBr 3 PSCs to prepare carbon-based FTO/SnO 2 -NiCl 2 /CsPbBr 3 /C cell devices. Through the morphological and structure characterization, it is found that introducing nickel chloride facilitates the formation of large and dense perovskite films with residual strain released and the passivation of interface defects. Simultaneously, an analysis of the interfacial energy level structure reveals that optimized energy levels enhance electron-hole separation and transport efficiency while effectively suppressing non-radiative recombination. The open-circuit voltage of the all-inorganic perovskite solar cell base on the SnO 2 -NiCl 2 electron transport layer reaches to 1.591 V, and optimal photoelectric conversion efficiency (PCE) of the solar cell devices has been improved from 8.11 % of the control to 9.33 % with NiCl 2 , and the unencapsulated device V OC long term stability maintained 96.9 % within 30 days under atmospheric environment conditions. This study provides new insights into the design of efficient electron transport layer materials to enhance the photovoltaic and environmental stability of PSCs.

Aiming to address the bottleneck issues of database complexity and signal drift in electronic nose systems, this study proposes a novel supplementary strategy for multi-component gas detection. The MEMS gas sensor developed here, based on temperature-programmed desorption (TPD), enables the extraction of multiple volatile target compounds in Baijiu (Chinese distilled spirits) through an adsorption process. Subsequently, the TPD spectrum is employed to derive characteristic signals of these target substances for identification. By incorporating this sensor into a Baijiu detection system and combining it with pattern recognition algorithms, accurate classification of aroma profiles has been successfully achieved for both known and unknown Baijiu samples across different brands. This multi-component gas detection method not only offers an effective complement to electronic nose technology but also provides valuable insights for improving the selectivity of metal oxide semiconductor (MOS) gas sensors.

Nano powder plays a key role in preparing high performance tungsten-based materials. It is necessary to synthesize powder with uniform element distribution, low impurity content, and fine particles for preparing higher performance tungsten-based materials with more uniform microstructure, with smaller grain size and higher densification. However, it is difficult to synthesize uniform oxide/carbide reinforced tungsten matrix composite powders with specific structure by traditional powder metallurgy method. In this manuscript, nano W-Y-Ti powders with core-shell structure were synthesized by organic chemical method. The average grain size of W-Y-Ti is 33.33 nm, which indicates the powder refinement is 1 order of magnitude compared with other methods. Moreover, due to the difference of Y 3+ and Ti 4+ , the Y phase tends to form core in W particle and the Ti phase tends to form shell around W particle in these powders synthesized by organic chemical method. This powder structure is conducive to in-situ dispersion of the reinforced phase during sintering and significantly improves the interface properties of the reinforced phase /W matrix phase. The W-Y-Ti composite prepared by SPS shows fine grain size (750 nm) and uniform distribution (Y 2 O 3 is distributed within the W grain, while Ti is distributed at the grain boundaries). It means the microstructure of the powder can be inherited to the bulk materials, which can improve the performance of these composites. This manuscript provides ideas and data basis for the synthesis and preparation of high-strength, tough and high-performance W-based composite materials.

This study presents a novel electrochemical approach for fabricating ethoxy terminated diamond (EtO-diamond) surfaces through high-voltage ethoxide ion treatment in ethanol. Using X-ray photoelectron spectroscopy (XPS), we systematically characterized the voltage dependent surface chemistry, revealing a two-step grafting mechanism: hydrogen abstraction by ethoxy radicals followed by covalent bond formation, as evidenced by C O and CH x peaks. The applied voltage critically governs surface composition, high voltages induced competing pathways (e.g., sp 2 carbon formation). Comparative hydrogen ion treatment enhanced CH x groups and avoided sp 2 carbon formation, indicating minimal oxidation.

Near-infrared (NIR) luminescent materials are promising NIR light sources for multifunctional applications; providing a strategy to tailor the emission and enhance the performance of NIR phosphors is crucial. Herein, a green HF-free synthetic strategy is realized to tune the NIR emission advantageously by substituting on the adjacent octahedral, completely different from breaking the d–d parity forbidden transitions of Cr3+ through conventional lattice distortion. Broadband NIR phosphor K2Na1−xLixAlF6:Cr3+ with excellent thermal quenching resistance is prepared using the hydrothermal method. Controllable emission tuning from 726 to 765 nm and broadening full width at half-maximum from 105 to 130 nm, is achieved by substituting Li+ for Na+, resulting from weakening the crystal field and increasing electron–phonon coupling. Lithium ions play a critical role in suppressing nonradiative relaxation of the emission centers, thereby significantly enhancing the emission intensity of K2NaMF6:Cr3+ (M = Al, Ga, In) phosphors. The as-fabricated prototype NIR phosphor-converted light-emitting diode device, exhibits significant promise in the fields of night vision and information encryption. This study provides an effective design strategy for developing broadband NIR luminescent materials with high efficiency and good thermal stability.

The efficient separation of bio-based solvents, such as acetone, butanol, and ethanol (ABE), is a critical challenge in biofuel production. Traditional separation methods, such as distillation, are energy-intensive, prompting the need for more sustainable alternatives. The salting-out process offers a promising approach by exploiting phase separation induced by inorganic salts, yet research on its equilibrium time remains limited. This study systematically investigates the salting-out performance and separation kinetics of ABE using K3PO4 under varying salt concentrations (200–400 g/kg) and temperatures (25–50°C). Results show that increasing salt concentration from 200 to 400 g/kg reduced the salting-out equilibrium time from approximately 100 min to 30 min for acetone and 1-butanol, while ethanol reached equilibrium in less than 5 min under all conditions. Higher temperatures further extended equilibrium time. This work highlights the positive effect of salt concentration on shortening equilibrium time and the counterintuitive effect of higher temperatures in extending equilibrium time, offering new insights into optimizing salting-out separation for biofuel production.

The production of semi-coke via low- and medium-temperature coal pyrolysis offers a promising avenue for coal utilization, yet the resultant wastewater poses significant treatment challenges due to its complex pollutants. This study introduces an innovative approach that shifts from “treatment” to “conversion,” utilizing phenolic substances and ammonium compounds in the wastewater to synthesize thermosetting phenolic resin (PR) and porous carbon (PC). These were activated with potassium hydroxide (KOH), yielding high-performance PC. Using response surface methodology (RSM), optimal conditions were identified: a KOH to PR ratio of 2.798:1, temperature of 816.43 °C, and duration of 1.22 h, achieving maximum iodine adsorption of 1457.22 mg/g. Thermal analysis and kinetic studies showed easier activation of PRs than methenamine, with mixed phenol-derived resins having the lowest activation energy. The pore structure analysis revealed that catechol, 2,3-dimethylphenol, and 2,6-dimethylphenol generated substantial mesopore and micropore volumes, whereas phenol and m-cresol primarily formed large pores. Ammonia addition rendered the PC pores round and regular. This research establishes a theoretical basis for transforming semi-coking wastewater into valuable resources and synthesizing advanced PC materials.

To endow silk with multifunctionality and expand its application fields, the silk fabric was treated with protocatechualdehyde to prepare a novel silk fabric with Schiff base structure (CAT@Silk). Then, CAT@Silk was immersed in iron (III) solution to chelate Fe 3+ to obtain flame retardant , antibacterial and UV-resistant silk fabric (CAT@Fe@Silk). Compared with the limiting oxygen index (LOI) value of the original silk, the CAT@Fe@Silk increased from 23.3 % to 35.1 %, and remained 32.4 % even after 20 laundering cycles (LCs), indicating excellent flame retardant durability. The UV protection coefficient of CAT@Fe@Silk was 67.74, which was higher than that of the original sample (21.02). In addition, CAT@Fe@Silk had good antibacterial effects against Escherichia coli ( E. coli ) and Staphylococcus aureus ( S. aureus ). This work constructed a dynamic cross-linking network that mimicked the adhesion of mussels generating from the complexation of catechol groups and Fe 3+ ions (catechol-Fe 3+ ), which not only endowed silk fabric with good flame retardancy, but also with UV resistance and antibacterial properties, demonstrating good potential application.
