CuBr 2 serves as a dual-functional additive to realize anion-cation co-passivation for perovskite defects. • CuBr 2 modification boosts crystallinity, increases grain size, and suppresses non-radiative recombination in perovskite films. • The optimized device yields enhanced efficiency, reduced hysteresis, and improved stability. Perovskite solar cells (PSCs) are a promising photovoltaic technology, characterized by high efficiency, low cost, and simple solution fabrication. However, the defects at grain boundaries impair optoelectronic performance and degrade long-term operational stability of PSCs. Herein, CuBr 2 additive was incorporated into the perovskite precursor solution, enabling Cu 2+ and Br⁻ to co-passivate iodine vacancies and uncoordinated Pb 2+ . The CuBr 2 -mediated perovskite films demonstrated the optimized crystallinity, facilitated interfacial carrier transportation, and diminished trap concentration. The PSCs achieved an improved efficiency from 18.53% to 20.10% and demonstrated significantly improved long-term environmental stability. This work provides a novel strategy for anion-cation co-passivation of defects in PSCs.

Achieving high CO selectivity in integrated carbon capture and hydrogenation (ICCH) remains a challenge because Ni-based dual functional materials (DFMs) inevitably catalyze competing methanation. Here, we demonstrate that trace chloride incorporation into Ni–Ca DFMs switches the dominant hydrogenation pathway from methanation to the reverse water−gas shift reaction. Chloride preferentially interacts with the CaO sorbent phase, forming Ca–Cl species that drive CaO densification and substantially lower the reducibility of the adjacent Ni active sites. Consequently, the 1% Cl-modified DFM attains 91.6% CO selectivity at 600 °C, in contrast to the 20.5% CO selectivity of the Cl-free counterpart. Cyclic testing confirms that the Cl-modified DFM maintains stable CO2 conversion and high CO selectivity. In situ experiments further show that chloride suppresses the deep hydrogenation of formate intermediates, thereby terminating the reaction at the CO-forming step rather than proceeding to CH4. This study establishes halogen engineering as an effective and operationally simple strategy for steering product selectivity in ICCH processes.

As a major carbon resource, carbon dioxide recycling can effectively address issues of the greenhouse effect and carbon resource shortages. Carbon dioxide based polypropylene carbonate (PPC) is a polymer material produced from carbon dioxide and propylene oxide, with advantages in environmental protection and sustainability. However, its relatively low thermal stability severely limits its application prospects. In this study, a novel cellulose acetate grafted carbon dioxide based polypropylene carbonate (CA-DMC-CO 2 ) ultrafiltration membrane was prepared by epoxidation and high-pressure catalysis of cellulose acetate side chains. The molecular weight of CA-DMC-CO 2 was 428,169 Da, and its thermal decomposition temperature reached 365 °C. The introduction of polycarbonate side chains endowed the CA-DMC-CO 2 ultrafiltration membrane with good hydrophilicity and excellent permeability, reaching 115.9 L/m 2 h, which performed better than the CA ultrafiltration membrane. In addition, good hydrophilicity of CA-DMC-CO 2 provided effective anti-fouling performance. This study highlights the potential for developing environmentally friendly and sustainable ultrafiltration membranes for practical applications.

Multi-enzyme immobilization offers promise for sensitive glucose detection, but traditional random co-immobilization hampers spatial control. Here, a compartmentalized system (HRP.PDA.GOx@NPC-10) was constructed by localizing GOx and HRP in the inner and outer polydopamine layers on hierarchical porous carbon spheres. This method can precisely control the spatial arrangement of enzyme molecules, effectively reduce the inhibitory effects of H2O2, and enhance the catalytic efficiency of multi-enzyme catalysis. The immobilization yields of GOx and HRP reached 54.6% and 65.0%, respectively. The resultant HRP.PDA.GOx@NPC-10 exhibited 1.65-folds higher activity than free enzymes and maintained favorable stability under extreme pH and temperature conditions. After 7 cycles, HRP.PDA.GOx@NPC-10 retained 75.66% of its initial activity, demonstrating reusability. Especially, HRP.PDA.GOx@NPC-10 has been demonstrated to possess a glucose detection limit as low as 0.28 μM and a reaction time of only 3 min, indicating its potential for practical glucose detection.

Polydiacetylene (PDA) materials are typically obtained through solid-state topochemical polymerisation of diacetylene monomers, a process that strongly depends on precise molecular packing and often leads to limited control over molecular weight and dispersity. Herein, we report a co-assembly-confined polymerisation strategy for the synthesis of polydiacetylene acids with intrinsically narrow dispersity. Phenyl diacetylene acid and 1-naphthalenemethylamine form co-assembled precipitates via acid – base interactions and aromatic stacking, providing a spatially restricted environment that satisfies the geometric requirements for topochemical polymerisation. Upon UV irradiation, efficient polymerisation of diacetylene units occurs within the precipitated phase. Subsequent side-chain amidation renders the polymers soluble, enabling solution-state molecular weight characterisation. Gel permeation chromatography reveals consistently narrow dispersity (Đ =1.1 ~ 1.2) across different polymerisation temperatures, while the apparent molecular weight remains tunable. This work demonstrates a simple and reproducible materials-oriented strategy to suppress chain-length divergence in polydiacetylene systems, offering new opportunities for controlled PDA materials.

FeCu-FeO x @SFCu 0.24 M-DP/RP enables ethylene–electricity cogeneration from ethane in oxide-ion-conducting SOFCs. • FeCu–FeO x promotes C–H bond activation and facilitates ethane dehydrogenation. • The cell achieves 78.4% ethane conversion and 81.7% ethylene selectivity at 750 °C. • Stable operation is sustained for 400 h with negligible performance degradation and coke deposition. Steam cracking of alkanes such as ethane accounts for over 90% of global ethylene production, but relies on energy-intensive, high-temperature pyrolysis, leading to significant carbon emissions and complex by-products that require costly purification. Enabling the co-generation of ethylene and electrical energy in oxide-ion-conducting solid oxide fuel cells (SOFCs), we design a highly selective anode for the electrochemical oxidative dehydrogenation of ethane (EOD-eth). The anode consists of a hierarchical heterostructure featuring oxygen-vacancy-rich FeCu-FeO x anchored onto a Sr 2 Fe 1.26 Cu 0.24 Mo 0.5 O 6-δ double-perovskite/Ruddlesden-Popper matrix (FeCu-FeO x @SFCu 0.24 M-DP/RP). The SOFCs demonstrate outstanding performance, maintaining CO 2 -free operation for over 400 h, while delivering a high-power density of 0.51 W cm −2 with an ethylene selectivity of 81.7% and an ethane conversion rate of 78.4% at 750 °C. Mechanistic investigations reveal that FeO x acts as both an effective oxygen-ion channel and an oxygen storage reservoir, activating ethane C–H bonds and promoting dehydrogenation, while FeCu enhances both ethylene selectivity and electronic conductivity. Beyond this specific reaction, the FeCu–FeO x –SFCu 0.24 M-DP/RP architecture embodies the essential attributes universally required of fuel electrode—including multivalent redox adaptability, robust structural resilience, and compatibility with diverse hydrocarbon or syngas fuels—thereby representing a broadly applicable catalytic platform for next-generation fuel-flexible SOFCs.

Antibiotics, as typical emerging contaminants posing significant ecological risks, are frequently detected in global coastal environments. Their biotransformation in marine environments depends on the stress responses of functional microbial communities, while the underlying response mechanisms remain unclear. Through integrated metagenomic and metabolomic approaches, this study systematically investigated the structural and functional responses of marine microbial communities during the co-metabolic degradation of sulfamethoxazole (SMX), a representative antibiotic. A marine microbial consortium was employed for SMX co-metabolism with alginate, prototypical marine natural organic matter, as the co-substrate. Results revealed that under SMX stress, the microbial community underwent a marked shift in OTU composition, alongside significant increases in richness and diversity. The dominant functional taxon Vibrionaceae exhibited a significant decrease in relative abundance from 97.0% to 82.7%, while Paracoccaceae with SMX degradation potential and other low-abundance (<0.01%) functional taxa were significantly enriched, collectively sustaining stable alginate metabolism and facilitating SMX co-metabolism. Co-occurrence network analysis revealed enhanced interspecies associations. Moreover, the functional profile of the microbial community was profoundly reshaped. Specifically, the microbial community activated adaptive responses, enhancing TCS activation, EPS and endospore production, flagellar motility and chemotaxis, antioxidant capacity and DNA repair, and antibiotic resistance, to mitigate the toxicity of SMX and its intermediates. Concurrently, metabolic strategies were altered via regulation of key pathways (e.g., carbohydrate metabolism and amino acid metabolism), which increased by 7.8% and 17.5% in relative abundance compared to the control, boosting energy supply and SMX-degrading enzyme synthesis to enable SMX co-metabolism. This study provides new insights into the response mechanisms of marine microbial communities to SMX stress and the ecological risk assessment of antibiotics in coastal waters.

A Ru nanocluster-coupled Co/Co 2 P heterostructure was rationally designed. • Ru nanoclusters regulate interfacial electrons and catalytic active centers. • Electronic modulation optimizes H* adsorption and accelerates water dissociation. • Hierarchical porous carbon improves mass transport and active-site accessibility. • The catalyst delivers excellent HER activity and overall water splitting. Achieving sustainable hydrogen production via water electrolysis relies heavily on the availability of efficient, stable, and economically viable electrocatalytic systems. Herein, we report a Ru nanocluster-regulated Co/Co 2 P heterostructure catalyst confined within a nitrogen-doped hierarchical porous carbon framework via an ion-exchange-assisted chemical vapor deposition strategy. The synergistic interaction among Ru nanoclusters and Co/Co 2 P heterointerfaces induces interfacial charge redistribution and modulates the electronic structure of the catalytic active sites, thereby facilitating the HER process. Combined experimental analyses and density functional theory calculations reveal that Ru nanoclusters effectively regulate hydrogen adsorption behavior, accelerate water dissociation kinetics, and reduce the Gibbs free Gibbs free-energy change of alkaline HER. Benefiting from the synergistic effects of heterointerface engineering, nanocluster regulation, and hierarchical porous architecture, the resultant optimized catalyst delivers a current density of 10 mA cm −2 at an ultralow overpotential as low as 40 mV, coupled with remarkable long-term cycling stability. Moreover, the Co-Co 2 P@Ru@NC||RuO 2 electrolyzer delivers a low cell voltage of 1.52 V at 10 mA cm −2 , demonstrating its potential for efficient overall water splitting. This work provides a rational strategy for constructing advanced electrocatalysts through synergistic electronic modulation and interface engineering toward sustainable hydrogen production.

Nitrogen-rich carbon dots loading with transition metals have received tremendous attention during the last decade due to superior catalytic performance in toxic pollutants degradation. The cobalt-doped carbon dots (Co-CDs) with high content of pyrrolic N have been synthesized in formamide solution via one-step solvothermal method. The pyrrolic N offers binding sites for the cobalt ions, forming Co N bond which facilitates the peroxymonosulfate (PMS) adsorption. It was found that the degradation in the Co-CDs/PMS system was dominated by high-valent cobalt-oxo species (Co IV =O) through a nonradical pathway. The simulation reveals that the formation of Co IV O species is favored by cleavage of the Co N bond and electron transfer from Co atom to O atom in the PMS. This study provides a deep understanding of PMS activation by carbon dots, and inspires rational design of environmental catalysts.

Steel slag-derived CaO-based composites were designed for high-performance heat storage. • Fe Mn co-modified composites retained 97% heat storage density after 20 cycles. • Fe Mn co-modification enhanced solar absorptance (82%) and compressive strength (1.26 N). • Fe Mn coexistence promoted oxygen vacancies and accelerated CO 2 uptake. CaO-based thermochemical energy storage (TCES) materials have attracted wide attention due to their high energy density, favorable reaction reversibility, and potential integration with CO 2 capture. Steel slag, as a Ca-rich solid waste naturally containing Fe and Mn, offers intrinsic advantages for developing structurally stable and solar-absorptive heat storage materials. However, current steel slag-derived TCES materials still suffer from limited understanding of the functional role of inherent transition-metal elements during repeated high-temperature cycling. In this work, Fe/Mn modified steel slag-derived CaO-based composites were rationally designed to clarify the individual and synergistic effects of Fe and Mn during high-temperature cycling. Fe/Mn containing phases formed a stable framework among CaO particles, effectively suppressing grain sintering and pore collapse. The Fe Mn co-modified sample exhibited superior overall performance. After 20 cycles, Fe Mn co-modified composite maintained a heat storage density of 1263 kJ/kg, corresponding to 97% retention of its initial capacity. The Fe Mn co-modified composite achieved a solar absorptance of 82% and a crushing strength of 1.26 N, which were 1.2 and 4.1 times higher than those of the unmodified sample, respectively. Moreover, the coexistence of Fe and Mn promoted electron transfer and oxygen vacancy formation through double-exchange interactions, thereby facilitating the carbonation reaction. This study demonstrates a targeted Fe Mn co-modification strategy based on the intrinsic Fe-rich feature of steel slag and provides new insights into the high-value utilization of steel slag for sustainable and durable TCES materials.

Electrochemical bicarbonate reduction reaction offers a promising pathway of integrating carbon capture and conversion, which could bypass the energy-intensive upstream CO 2 regeneration and downstream CO 2 separation processes. Since the limited in-situ CO 2 ( i -CO 2 ) generation at the electrochemical interface, designing catalysts with highly exposed active sites and optimized structures is the key to achieve efficient bicarbonate reduction. In this work, we prepared a series of NiCu-based porous catalysts, using SiO 2 hard templates of different sizes to tune the pore structure. There exist an optimal mesopore size that could balance the mass transport, local i -CO 2 enrichment, and active-site distribution in bicarbonate electroreduction to CO. The optimal catalyst NiCu-TE achieved a bicarbonate-to-CO electrolysis at 100 mA cm −2 with 92.4% Faradaic efficiency (FE) and 41.3% energy efficiency (EE) in the membrane electrode assembly (MEA). It maintained a FE CO of 68.3% at a current density of −300 mA cm −2 . We found that pore architecture engineering, rather than pore size alone, is crucial in constructing efficient electrochemical microenvironments for bicarbonate electroreduction.
