CO is a key product of CO 2 electroreduction (CO 2 ER) and an important feedstock for the production of hydrocarbons and alcohols. Herein, we synthesized electrocatalysts by growing Cu nanocluster on manganese oxide (Cu n -Mn 3 O 4 ) for CO 2 ER. In 0.5 M KHCO 3 electrolyte using an H-cell, the optimized Cu 0.4 -Mn 3 O 4 achieved a Faradaic efficiency for CO (FE CO ) of 88.5 ± 2.3% and a current density of 14.3 ± 0.2 mA cm −2 at − 0.6 V vs. RHE, while substantially suppressing the hydrogen evolution reaction (HER). The better performance was due to the electrons transferred from Mn to CO 2 by Cu as a shuttle and anchored Cu nanoclusters shifted the d-band center toward the Fermi level, which was more conducive to the intermediate formation. In situ electrochemical attenuated total internal reflectance (EC-ATR) spectroscopy and density functional theory (DFT) calculations revealed the *COOH intermediate (1399 cm⁻ 1 ) along the CO 2 → *COOH → *CO → CO pathway. Moreover, the DFT calculations further demonstrated the Gibbs free energy barrier (ΔG) of the key steps in the CO 2 ER pathway and the corresponding intermediate configurations, which were used to reveal the relationship between the catalyst structure and CO 2 ER performance. The design of the metal/metal oxide electrocatalyst in this study provides a new perspective for the highly selective reduction of CO 2 to CO. Graphical

Room-temperature plasma-assisted catalysis represents an important pathway for CO 2 valorization. Rational design of catalysts tailored to plasma environment holds significant potential for improving catalytic efficiency. Unprecedentedly, we report a coordination-engineering strategy to fabricate the Fe/Cu mix-metal organic framework (Fe/Cu-MOF) catalysts for plasma-driven CO 2 dissociation into CO. Precise modulation during synthesis revealed an optimal Fe:Cu ratio of 0.44:0.56 to generating synergistic active sites favorable for CO production. The in situ-formed FeCu-based catalyst exhibited exceptionally high CO space-time yield of 32.3 mmol·gcat-1·h-1 under room-temperature plasma conditions. The coordination-tailored electronic structure enables the dynamic variations in the oxidation states of Fe/Cu upon plasma activation, thus facilitating sustained CO 2 activation. This work establishes atomic-level control of bimetallic sites as a powerful paradigm for plasma-catalytic systems. Graphical For the first time, Fe-Cu bimetallic metal-organic frameworks (MOFs) synthesized via a one‑pot solvothermal method were used for efficient decomposition of CO 2 into CO with excellent stability under nonthermal plasma (NTP). This integrated approach offers fundamental insights and technical support for the development of robust catalysts under plasma conditions.

Background Although sensor arrays are powerful for discriminating glycosaminoglycans, the construction of a sensor array is usually cost and labour inefficient. With the purpose to acquire a high dimensional response data using only a limited number of dyes, the rational assembly of fluorescent dye molecules may provide an alternative approach. We envision that co-assembling different dyes within a supramolecular structure can trigger multiple photophysical processes, which should produce high dimensional optical signals. Results A supramolecular AIEgen-porphyrin co-assembly is synthesized by assembling a negatively charged AIEgen ( TPE ) and meso-tetra(4-carboxyphenyl)porphine ( TCPP ) on the surface of a cationic polymer saying poly(diallyldimethylammonium chloride) ( PDDA ). With the co-assembly strategy, the aggregation-induced emission of TPE , the aggregation-caused quenching characteristic of TCPP , and especially, the Förster Resonance Energy Transfer efficiency from TPE to TCPP can be manipulated by a dynamic dye assembly approach. A sensor array is thus readily constructed by varying the loading ratio of TPE and TCPP on the surface of PDDA . Significance The sensor array is determined to be powerful for pattern recognition of various glycosaminoglycans even in 100% serum media through competitive compaction or removal of the aggregated TPE and TCPP dyes on the PDDA surface. It can be successfully applied for accurate and reliable detecting trace GAG analogues in Hep samples and identifying unknown GAG samples with an accuracy of 96.88%.

The emergence of aggregation-induced emission (AIE) luminogens has revolutionized biomedical theranostics, yet the exploration of natural AIE-active therapeutics remains nascent. Herein, we propose a novel “AIE-Pharmacology” paradigm, employing the natural flavonoid acacetin as an intrinsic AIEgen with pharmacological activity for self-monitored therapy of asthenozoospermia. Overcoming traditional aggregation-caused quenching (ACQ), acacetin utilizes its aggregation-enhanced emission and excited-state intramolecular proton transfer (ESIPT) properties to enable simultaneous treatment, high-contrast imaging, and tracking. We developed an extracellular vesicles (EVs)-based co-delivery system loaded with acacetin and β-Nicotinamide mononucleotide (NMN). This nanoplatform (EVs@N + A) exhibits inherent affinity for the testicular microenvironment. Upon targeted accumulation, released acacetin triggers a potent anti-ferroptotic response by upregulating GPX4 and SLC7A11 and suppressing lipid peroxidation. In parallel, NMN elevates intracellular NAD + levels, reprogramming cellular metabolism and restoring ATP production. This dual strategy—inhibiting ferroptosis and rejuvenating metabolism—effectively rescues sperm function, enhancing sperm count, motility, and progressive movement in vivo . Our work reports acacetin as a multifunctional AIEgen in reproductive medicine and establishes a traceable theranostic platform, introducing the “AIE-Pharmacology” paradigm as a promising approach for treating male infertility and other diseases.

Co-upcycling strategy enables cross-system conversion from LiB to Zn I 2 chemistry. • Upcycled battery exhibits high I 2 redox kinetics and dendrite-free Zn plating. • Anode-free design validates interfacial engineering of recycled electrode materials. With a growing amount of spent lithium-ion batteries estimated to accumulate over years, developing efficient recycling methodologies becomes urgent. Despite many efforts in this direction, the current routes require costly procedures with limited efficiencies and give rise to the under-utilization of recovered materials over both electrodes. Here, we put forward a co-upcycling strategy by integrating hydrometallurgy with Joule heating to address these concerns. Inspired by the Zn − iodine battery research community, we fully utilize the regenerated anode and cathode species from SLIBs into constructing prototype Zn − I 2 battery affording dual-electrode regulation. Operando spectroscopic characterizations and theoretical simulations reveal the co -upcycled materials simultaneously help mitigate polyiodide shuttle effect and ameliorate Zn deposition reversibility. Leveraging this strategy, the thus-derived anode-free Zn − I 2 pouch cell demonstrates an energy density of 229 Wh kg −1 . Techno-economic analysis further suggests the material usage and energy consumption in our protocol are notably low. This work is anticipated to establish an innovative paradigm of environmentally sustainable solutions toward next-generation energy storage. Integrated Joule heating and hydrometallurgical approach is developed to upcycle dual electrodes into anode-free zinc−iodine batteries. Temperature-mediated regulation endows the cobalt-limited catalysts with high cathode loading and shuttle inhibition affording, while graphite serves as functional anode. This work reduces raw material cost, energy consumption and improving the overall energy density. Download: Download high-res image (130KB) Download: Download full-size image

Developing efficient, recyclable heterogeneous catalysts for the oxidation of p-methoxytoluene (p-MT) remains a critical challenge in industrial organic synthesis. Herein, a ternary Co-Mn-Ce oxide catalyst was synthesized via co-precipitation and systematically optimized to address limitations in mass transfer and catalyst reusability. By modulating the Ce content, the structural evolution from cobalt‑manganese spinel phases to CeO 2 -dominated crystallites was demonstrated, significantly influencing catalytic performance. The CoMn 3 Ce 1.9 catalyst with high Ce loading exhibited a p-MT conversion of 95.0% under mild conditions, outperforming the low-Ce analogs, which showed only 50–60% p-MT conversion. Characterization revealed that CeO 2 -rich catalysts featured larger average pore sizes (18 nm vs. 2–4 nm for spinel-dominated systems), mitigating diffusion constraints and enhancing oxygen activation. High-concentration experiments (8 mL p-MT) maintained 77.7% conversion after 12 h, but with increased esterification to p-methoxybenzyl acetate (p-MBAc). Remarkably, the catalyst retained >70% activity over four runs. This work highlights the optimized pore architecture in overcoming traditional limitations of spinel-based catalysts, offering a sustainable, scalable strategy for aromatic aldehyde synthesis. The findings provide critical insights into designing multifunctional heterogeneous catalysts for selective C(sp 3 )-H bond activation, with broad implications for green chemical manufacturing.

Single-atom catalysts have found widespread application in selective hydrogenation reactions partially due to their well-defined active site structures, which ensure exceptional chemical selectivity. However, the limited binding sites on single-atom catalysts hinder their application in hydrogenating larger multidentate substrates (e.g., benzonitrile). In this work, we introduced a heteronuclear Rh-Co dual-atom catalyst stabilized on the defective graphene supports (Rh 1 Co 1 /ND@G), which resolves the activity-selectivity trade-off in nitrile hydrogenation reaction. The Rh 1 site primarily activates H 2 , whereas the Co 1 site synergistically optimizes the adsorption of benzonitrile. The cooperative interaction between Rh-Co dual sites enhances the activation of the C ≡ N bond, significantly reducing the apparent activation energy compared to Rh SACs. The Rh 1 Co 1 /ND@G catalyst achieves exceptional performance under mild reaction conditions, delivering a TOF of 4068 h -1 with >98% dibenzylamine selectivity, surpassing all previous reported heterogeneous catalysts. Remarkably, the Rh 1 Co 1 /ND@G catalyst still maintains robust catalytic performance even after 12 cycles. This work not only presents a breakthrough in dual-atom catalyst design for nitrile hydrogenation, but also opens an avenue for developing high-performance industrial hydrogenation catalysts.

Abstract Two structurally similar cocrystals, colchicine/L-malic acid (COL/L-MA) and colchicine/D-tartaric acid (COL/D-TA), were prepared to investigate their co-crystallization behavior via in situ ATR-FTIR spectroscopy. Ternary-phase diagrams combined with a 1:1 solution complexation model revealed a strong complexation effect between the active pharmaceutical ingredient and both co-crystal formers. The conventional calibration strategy was applicable to the COL/L-MA system; however, an alternative calibration method was established for the COL/D-TA system to avoid undesired premature nucleation during spectral calibration. Kinetic analysis indicates that cocrystal formation governs the overall rate of the COL/L-MA process, while dissolution of D-TA constitutes the rate-determining step for COL/D-TA, which originates largely from the solubility difference between the two co-crystal formers. Intriguingly, abnormal apparent concentration rises were detected for both systems, yet they arise from fundamentally different origins: mutual solubilization accounts for the concentration surge in COL/L-MA, whereas the anomaly in the COL/D-TA system stems from complexation-induced spectral enhancement instead of real concentration variation. The proposed model successfully distinguishes these spectral artifacts, allowing credible identification of intensive nucleation events and supporting process-condition optimization. This work offers mechanistic understanding and practical guidance for co-crystallization systems containing structurally similar co-crystal formers.

Low dimensional quantum materials have been extensively studied within the physics community, among which $\mathrm{C}{\mathrm{o}}^{2+}$ is one of the most popular magnetic ions to be embedded into the structural motif. $\mathrm{CoN}{\mathrm{b}}_{2}{\mathrm{O}}_{6}$ and $\mathrm{CoT}{\mathrm{a}}_{2}{\mathrm{O}}_{6}$ both have adopted an effective spin-1/2 state, with the former attracting enduring interest while the latter being rarely investigated. This difference can be attributed to their distinct crystal structures, not only in crystal systems, but more important, how the $\mathrm{Co}{\mathrm{O}}_{6}$ octahedra are connected. We successfully merge these two compounds together and map out the doping limits. We find out Ta and Nb dopants modify the properties of the parent compounds in subtle but different ways and construct a magnetic phase diagram of the $\mathrm{Co}{(\mathrm{N}{\mathrm{b}}_{x}\mathrm{T}{\mathrm{a}}_{1\ensuremath{-}x})}_{2}{\mathrm{O}}_{6}$ $(0\ensuremath{\le}x\ensuremath{\le}1)$ series. In addition, our results suggest that Ta-doping may pave a way to strengthen the lower-dimensional quantum phenomena in $\mathrm{CoN}{\mathrm{b}}_{2}{\mathrm{O}}_{6}$ before its crystal structure starts to melt down.

The development of M-N-C catalysts (M = Fe, Co, Ni, etc.) was hindered by poor distribution of metal species and large particle size. In this work, alkaline additives were introduced during the precursor synthesis stage to regulate the distribution of metal components. Through hydrothermal and pyrolysis methods, Co-N-C catalysts (Co-N-C-NH3, Co-N-CO3, and Co-N-C-OH) were synthesized by using folic acid as the carbon and nitrogen source, cobalt chloride as metal salt, and ammonia solution, sodium carbonate solution, and sodium hydroxide solution as alkaline additives, respectively. The influence of different alkaline additives on the morphology, composition, and structure of Co-N-C catalysts was systematically analyzed through systematic characterization methods. The results indicated that the Co-N-CO3 catalyst prepared using sodium carbonate solution has a largest specific surface area, smallest and most evenly distributed Co nanoparticles. Moreover, the catalytic activity of the prepared Co-N-C catalyst in the hydrogenation of nitrobenzene was evaluated, and the influence of alkaline additives on its catalytic performance was further explored. Among them, the Co-N-CO3 catalyst achieved the best in the hydrogenation of nitrobenzene after reacting at 110 °C and under 1 MPa hydrogen for 3 hours, with a nitrobenzene conversion rate of over 99%. Comparative experiments confirmed that Co nanoparticles and Co-Nx sites constituted the active centers of the catalytic reaction. This strategy provides theoretical support and practical basis for optimizing the performance of Co-N-C catalyst.

Non-noble metal-based catalysts are promising candidates for efficient glucose hydrogenation. However, their practical application remains challenging due to limited intrinsic activity and poor stability. Herein, we demonstrate that the inverse catalyst featuring zirconium oxide nano-islands immobilized on a metallic Co matrix exhibits superior activity compared to the conventional supported catalyst. The optimal ZrO 2 /Co catalyst achieves an outstanding sorbitol productivity of 37.6 g Sor g Cat -1 h -1 and displays excellent reusability over 11 consecutive runs. Kinetic studies and comprehensive characterizations uncover that the inverse Zr-Co interface enriches oxygen vacancies and synergistically modulates the adsorption of glucose and hydrogen, thereby prompting the selective hydrogenation of carbonyl groups. This work offers a rational design strategy for developing high-performance and durable inverse catalysts for biomass hydrogenation.

A series of Co/MgAl 2 O 4 (CM1A2) catalysts with controlled cobalt loadings (0.5–3 wt%) were successfully synthesized using a co-precipitation method and tested for CO 2 -mediated oxidative dehydrogenation of ethane (CO 2 -ODHE) reaction. 1.5CM1A2 catalyst (1.5 wt%) displays the best catalytic performance, superior to other transition metal-based catalysts with ethane conversion, CO 2 conversion and ethylene yield at 700 °C about 42%, 8% and 38%, respectively. The catalysts were systematically characterized by X-ray diffraction (XRD), Raman spectroscopy, Ultraviolet-visible spectrophotometry (UV–vis), X-ray photoelectron spectroscopy (XPS), and in-situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). The results reveal that the non-reducible MgAl 2 O 4 support possesses remarkable thermal stability and the obtained catalysts exhibit resistance to dry reforming of ethane (DRE) reaction, facilitating prolonged high catalytic activity and selectivity at 650–700 °C. Co 3+ was primarily in Co 3 O 4 , whereas Co 2+ was identified within both Co 3 O 4 and highly stable CoAl 2 O 4 ; however, Co 2+ /Co 3+ decreases continuously along with cobalt loading increase. In addition, CoAl 2 O 4 promotes ethylene formation. In Co 3 O 4 , Co 3+ is more susceptible to reduction to metallic Co 0 under the reaction atmosphere, promoting reverse water-gas shift (RWGS) reaction and finally enhancing oxidative dehydrogenation of ethane. These insights offer a valuable framework for the rational design of efficient and durable catalysts for the CO 2 -ODHE process.
