The electroreduction of CO 2 to CO is fundamentally hindered by sluggish COOH intermediate formation and the competing hydrogen evolution reaction. Herein, we show that this challenge can be addressed through the dynamic in-situ reconstruction of a CuO/In 2 O 3 precursor under electrochemical CO 2 reduction conditions. By employing in-situ electrochemical spectroscopy techniques in combination with theoretical calculations, we demonstrate that the presence of In 2 O 3 facilitates the complete reduction of CuO to metallic Cu. This in-situ reconstruction produces electron-rich Cu-In 2 O 3 interfaces, characterized by a reduced work function and an upshifted Cu 3 d -band center, which promote CO 2 activation and the formation of COOH/CO intermediates. Those interfacial properties lead to a pronounced electronic coupling that endows the electrocatalyst with high CO 2 -to-CO selectivity at low potentials. Specifically, the optimised Cu/In 2 O 3 achieves CO Faradaic efficiency above 90% across −0.5 to −0.9 V vs. the reversible hydrogen electrode, reaching 97.6% at −0.6 V in a H-type cell, and sustains a high CO selectivity of 96.0% even at an ultralow potential of −0.2 V in a flow-cell configuration. These findings underscore the crucial role of electron-rich interfaces in directing CO 2 reduction with exceptional selectivity and activity toward CO formation.

Electrochemical H 2 O 2 synthesis via the two-electron oxygen reduction reaction (2e – ORR) offers a green alternative to the energy-intensive anthraquinone process, but its practical viability is hindered by the sluggish and low-value oxygen evolution reaction (OER) at the anode. Here, we present an energy-saving paired electrolysis strategy that replaces anodic OER with methanol oxidation reaction (MOR) using a ternary Mn-doped NiCo layered double hydroxide (Ni 0.50 Co 0.30 Mn 0.20 LDH) catalyst in situ grown on nickel foam (NF) by a one-step hydrothermal method. The optimized catalyst achieves a low MOR potential of 1.32 V RHE at 10 mA cm –2 and a formate Faradaic efficiency of 92.9%, outperforming its undoped counterpart (Ni 0.61 Co 0.39 LDH, 1.37 V RHE and 83.3%). In-situ Raman spectroscopy and density functional theory calculations reveal that Mn doping lowers the energy barrier for the Ni 2+ /Ni 3+ redox transition, facilitating the generation of catalytically active Ni 3+ species. When coupled with graphitized hydroxyl-functionalized multi-walled carbon nanotubes coated on carbon paper (CNTs@CP) as the 2e – ORR cathode in a two-electrode electrolyzer, at the operation condition of 50 mA cm –2 , the 2e – ORR||MOR system delivers a cell voltage reduction of 254 mV, enabling a 10.3% decrease in energy consumption for H 2 O 2 production, compared with the conventional 2e – ORR||OER system. Moreover, the simultaneous generation of value-added formate at the anode yields a 97.9% increase in net economic benefit. This work establishes a generalizable paired electrolysis paradigm for the decentralized, energy-efficient, and economically viable co-production of H 2 O 2 and high-value chemicals.

Ulcerative colitis (UC) is defined as a chronic inflammatory disease with recurrent episodes, and current therapeutic strategies for this gastrointestinal disorder often fail to achieve satisfactory clinical outcomes. This clinical challenge underscores an urgent requirement to develop alternative treatment strategies. Patchouli alcohol (PA), a natural compound exhibiting anti-inflammatory and antioxidant properties, has shown potential; however, its precise mechanisms of action in UC remain to be fully elucidated. Our study shows that PA can effectively alleviate the symptoms of dextran sulfate sodium (DSS)-induced UC in mice. This therapeutic effect is achieved by reducing intestinal barrier impairment and inhibiting inflammatory reactions. In an LPS-induced inflammatory model using RAW264.7 cells, PA significantly downregulated the mRNA expression of il-1β and il-6 . Mechanistically, protein disulfide isomerase (PDI) was identified as a direct target of PA. By inhibiting IRE1 activation via PDI, PA mitigates endoplasmic reticulum stress, thereby reducing intestinal epithelial injury and ultimately alleviating the severity of UC. In this research, it is determined that the ability of PA to protect the intestinal epithelial barrier is brought about by its specific targeting of PDI, which alleviates consequent endoplasmic reticulum stress and prevents cellular damage.

The hydroxyethyl radical (•CH(CH 3 )OH)-mediated pathway, by avoiding the formation of aldehyde intermediates, constitutes a promising approach for the highly selective photocatalytic synthesis of benzimidazoles from ethanol and o -phenylenediamine. However, inefficient reactant adsorption and activation, as well as severe recombination of photogenerated charge carriers of traditional photocatalysts, impose a fundamental challenge for this reaction pathway. Herein, we construct an oxygen vacancy (V O )-rich Nb 2 O 5 decorated with Pt nanoparticles (NPs), which exhibits the highest photocatalytic activity to date, with production rates of 4.0 mmol g −1 h −1 for 2-methylbenzimidazole and 10.2 mmol g −1 h −1 for H 2 , respectively. The synergistic interaction between V O and Pt NPs markedly promotes the migration and separation of photogenerated charge carriers. The electron-accumulating Pt NPs drive efficient H 2 evolution through proton reduction, while the engineered V O sites enhance ethanol adsorption and selectively activate α-C–H bond cleavage to generate •CH(CH 3 )OH radicals, suppressing the accumulation of N-ethyl-2-methylbenzimidazole by-products inherent to conventional aldehyde-mediated reaction pathways, significantly facilitating the co-production of benzimidazoles and H 2 . This work achieves directional pathway regulation via rational design of semiconductor defects and metal co-catalysts, establishing a radical-mediated strategy for efficient and selective green synthesis of N-heterocyclic compounds.

Electrocatalytic carbon dioxide reduction (CO 2 RR) offers a highly promising strategy for achieving carbon-neutral energy cycles by converting CO 2 into high-value chemicals and fuels. While it remains challenging to modulate the electronic environment precisely and systematically around the active sites of catalysts to steer the reaction toward desired products, especially hydrocarbons such as methanol (CH 3 OH). This study reports a strategy that enables highly efficient CO 2 RR to CH 3 OH under neutral conditions by fine-tuning the electronic environment of cobalt center in cobalt phthalocyanine (CoPc) through nitrogen-rich supports. Among them, CoPc/TiN achieved a high Faradaic efficiency of 53.28% for CH 3 OH production at –1.0 V ( vs . reversible hydrogen electrode), with a partial current density of 68.76 mA cm ‒2 . X-ray photoelectron spectroscopy and extended X-ray absorption fine structure analyses reveal that electronic modulation at Co-N sites of CoPc, which can promote *HCO coupling, and it’s a critical step in CH 3 OH formation. Theoretical calculations further demonstrate that nitrogen carriers induce electronic redistribution within the Co center coordination environment. The projected density of states of *HCO on CoPc loaded on (Si)N-MXene)/TiN/C 3 N 4 shown electron deficient characteristics. It promotes the formation of *HCO, thereby facilitating CH 3 OH synthesis. This work provides new mechanistic insights into CO 2 RR for CH 3 OH and opens new avenues for designing efficient catalysts.

Natural gas vehicles (NGVs) offer significant environmental advantages by reducing pollutant emissions, but effective exhaust treatment remains a challenge due to high methane emissions and catalyst deactivation over time. This study introduces a core-shell Pd@CeO 2 /Al 2 O 3 three-way catalyst (TWC) designed to enhance the efficiency and durability of NGV exhaust treatment. The core-shell structure significantly improves catalytic performance. The optimized Pd@Ce/Al (S-500) catalyst demonstrates excellent low-temperature activity, with T 50 values of 336 °C for CH 4 and 397 °C for NO. It also achieves remarkable reductions of 113 and 177 °C in the T 90 for CH 4 and NO conversion, respectively, compared to the non-core-shell counterpart, Pd-Ce/Al (S-500). Characterizations reveal enhanced metal-support interactions, increased oxygen vacancies, and optimized Pd-CeO 2 interfaces as key active sites. Density functional theory calculations further demonstrate that the core-shell structure facilitates electron transfer at Pd-CeO 2 interfaces and lowers energy barriers for three-way reactions, enhancing catalytic efficiency. Notably, the core-shell Pd@Ce/Al (S-500) catalyst maintains high conversion efficiency for CH 4 and NO, with only slight losses (5.5% and 6.6%, respectively) over a 100-h time-on-stream stability test, following 16 h of harsh hydrothermal aging at 800 °C, showcasing its long-term stability. These findings provide a deeper understanding of the role of the core-shell Pd@CeO 2 structure in Pd-based TWCs and offer valuable insights for designing durable and efficient catalysts to meet the stringent emission standards of NGVs.

Lung squamous cell carcinoma (LUSC) is a prevalent and aggressive form of lung cancer with limited therapeutic options. Sanguinarine (SAG), a prominent benzophenanthridine alkaloid derived from Zanthoxylum nitidum (Roxb.) DC, exhibits established anti-tumor activity; however, its molecular mechanisms in LUSC remain incompletely defined. In this study, the anti-cancer effects and underlying mechanisms of SAG were systematically investigated in vitro and in vivo . Cell viability and death were evaluated using methyl thiazolyl tetrazolium (MTT) assays, colony formation assays, flow cytometry, transmission electron microscopy (TEM), and Western blotting (WB). Drug affinity responsive target stability (DARTS) combined with liquid chromatography–tandem mass spectrometry (LC-MS/MS), molecular docking, cellular thermal shift assay (CETSA), and surface plasmon resonance (SPR) were employed to identify and validate molecular targets of SAG. The results demonstrated that SAG simultaneously induces apoptosis and ferroptosis in LUSC cells by directly targeting the endoplasmic reticulum (ER) chaperone binding immunoglobulin protein (BiP). Silencing of BiP markedly attenuated SAG-induced apoptosis and ferroptosis, confirming its essential role in this process. Mechanistically, SAG up-regulates BiP expression and activates the protein kinase R-like endoplasmic reticulum kinase (PERK)/eIF2α/C/EBP homologous protein (CHOP)/GADD34 signaling axis of ER stress (ERS), ultimately leading to dual induction of apoptosis and ferroptosis in vitro and in vivo .

Based on the kinetic and thermodynamic equations, a comprehensive mathematical model for the continuous esterification process of polyester polyols was developed, which was carried out in an innovational bubbling reactive distillation tower (BRDT) at atmospheric pressure. In this new type of reactor, direct esterification between ethylene glycol and adipic acid was accomplished efficiently and rapidly. A bench BRDT with the height of 2 m was applied for the esterification process of poly (ethylene adipate) (PEA). In the continuous operation, linear oligomers were discharged from the bottom of the column, while water passed a few column trays and a packing section as a condensation byproduct. The influence of major operating conditions on reactor performance was also simulated. Simulation results were in good agreement with experimental data, providing a strategy for developing and optimizing this process.

CO 2 hydrogenation to ethanol represents a pivotal pathway for valuable utilization of greenhouse gas CO 2 , yet conventional catalysts are still limited by active-phase instability and undesirable byproduct selectivity. Herein, we propose a dual-components catalyst system synergized by hydrophobic carbon-encapsulated Fe-based catalyst (NaFe@C) and K modified CuZnAl component (KCZA), which achieves ultra-high ethanol selectivity of 35% under optimized conditions (5 MPa and 320 °C). KCZA initiates the CO 2 activation via reverse water-gas shift reaction and supplies oxygen-containing intermediates (mainly CH x O*, x = 0, 1, or 2). NaFe@C component is mainly responsible for the C–O activation for CH x * formation and C–C coupling between CH x * and CH x O*, as well as the following hydrogenation step for ethanol synthesis. Notably, the hydrophobic carbon shell in NaFe@C plays a critical role in tailoring the oxidation behaviors of Fe-based active sites and optimizing the phase ratio of Fe 3 O 4 / χ -Fe 5 C 2 via water management. Multiple characterization and theoretical simulation results clarify that the unique electronic property of Fe-based active sites endowed by the optimized phase ratio is beneficial to boost the ethanol synthesis performance by balancing the coverage of key intermediates and lowering the energy barrier of essential steps. This work is promising to provide guidance for the rational design of advanced catalysts for targeted transformation of CO 2 or syngas into ethanol and beyond.

Electrocatalytic reduction of nitrogen into ammonia (NH 3 ) is a highly attractive but challenging route for NH 3 production. We propose to realize a synergetic work of multi reaction sites to overcome the limitation of sustainable NH 3 production. Herein, using ruthenium-sulfur-carbon (Ru-S-C) catalyst as a prototype, we show that the Ru/S dual-site cooperates to catalyse eletrocatalytic nitrogen reduction reaction (eNRR) at ambient conditions. With the combination of theoretical calculations, in situ Raman spectroscopy, and experimental observation, we demonstrate that such Ru/S dual-site cooperation greatly facilitates the activation and first protonation of N 2 in the rate-determining step of eNRR. As a result, Ru-S-C catalyst exhibits significantly enhanced eNRR performance compared with the routine Ru-N-C catalyst via a single-site catalytic mechanism. We anticipate that our specifically designed dual-site collaborative catalytic mechanism will open up a new way to offers new opportunities for advancing sustainable NH 3 production.

For natural oxygenic photosynthesis, there is a consensus that H 2 O is oxidized to molecular oxygen by photosystem II (PSII) in the grana, while CO 2 assimilation takes place, long after oxygen evolution, in light-independent reactions, for example, through the Calvin-Benson Cycle in the stroma. Here, we report, for the first time, light-driven CO 2 assimilation by the PSII core complex, where the formation of methanol, along with the oxygen evolution, is validated by in - situ mass spectrometry, gas chromatography and isotopic labeling experiments. Such an unusual CO 2 assimilation is likely to be a simultaneous event along with the usual electron transfer occurring in normal light–independent assimilation. This discovery is extraordinary and is of great significance as it may substantially modify our understanding of the mechanism of photosynthesis.

Back surface recombination could have some adverse effects on superstrate antimony selenide (Sb 2 Se 3 ) solar cells. Anode interface modification, such as inserting a buffer layer with appropriate energy-level matching, is necessary. Here, a novel interfacial material, pyrolytic ammonium metatungstate (PAMT), prepared by spray pyrolysis deposition, was introduced to modify the back contract of antimony selenide solar cells. Morpho-structural and thermal analysis showed that this material is different from crystalline molybdenum oxide powder. Monology characterization showed that PAMT preferentially fills the space of the Sb 2 Se 3 grain boundary. The J–V test showed that this layer improved the interfacial contract between the absorber and the back electrode. The PAMT layer showed suitable energy matching with Sb 2 Se 3 , providing an effective channel for hole carriers transport from the absorber to the anode, and largely reducing back contact surface recombination. As a result, the PAMT-modified Sb 2 Se 3 device exhibited a much higher photovoltaic performance, significantly improving the efficiency from 5.27% to 6.11%. Graphical Abstract
