Photovoltaic
(PV) encapsulants play a pivotal role in ensuring
the long-term reliability of solar modules by protecting sensitive
cells from moisture ingress, mechanical stress, and ultraviolet (UV)
degradation. However, conventional encapsulant materials, such as
ethylene-vinyl acetate, polyolefin elastomer, and polyvinyl butyral,
exhibit several inherent limitations, including a high water vapor
transmission rate, poor delamination resistance, and easy formation
of optical haze under long-term UV irradiation in hygrothermal conditions.
To address these challenges, we herein design a CO 2 -derived
aliphatic polycarbonate-based thermoplastic polyurethane (TPU) as
a PV encapsulant, which combines high transmittance (>90.5%), flexibility,
superior water vapor barrier properties (WVP < 12.42 g·mm
m –2 day –1 ), moisture insensitivity,
and strong adhesion to PV glass and backsheet substrates. More specifically,
the multiblock TPU is synthesized via the polyaddition of poly(propylene
carbonate)diol, polyether diol, hexamethylene diisocyanate, and 1,4-butanediol.
Upon optimizing the chemical composition and incorporating proper
additives (e.g., silicone coupling agents, UV absorbers, antioxidants),
the encapsulant achieves enhanced interfacial adhesion with a peel
strength of 87.2 N cm –1 and maintains a residual
peel strength of 73.4 N cm –1 following accelerated
UV aging. Additionally, the adhesion mechanism based on TPU is proposed
and preliminarily elucidated. This study tackles key challenges in
photovoltaic module encapsulation by developing this high-performance
alternative material, demonstrating significant potential for large-scale
industrial applications.

Conventional carbon dioxide (CO 2 ) capture systems are constrained by limited uptake capacity and energy-intensive regeneration. Here, we formulate a microporous carbon capture solution (MCCS) by dispersing a permanent-porosity framework (ZIF-67) in a liquid absorbent, coupling solvent-excluded physisorption with chemical uptake and boosting the CO 2 capture capacity by ∼45%. Instead of bulk thermal stripping, we implement interfacial, microbubble-activated regeneration (MAR) with a decreased monoethanolamine (MEA) loss rate by ∼38%. Microbubble activation refreshes gas-liquid-solid contact to liberate 100% physiosorbed CO 2 , whereas microbubble-collapse events that mechanically trigger contact electrocatalysis (CEC), enabling interfacial hydroxyl radicals (•OH) that cleave carbamates under mild conditions and regenerates a substantial additional 37 to 55% of chemically absorbed CO 2 . Theoretical analyses reveal that •OH is the key species governing CO 2 regeneration in the CEC-MAR process through oxidative carbon-nitrogen bond cleavage, followed by •H-assisted intermediate reduction to regenerate the amine. To approach engineering relevance, we realize kilogram-scale zeolitic imidazolate framework (ZIF) synthesis under ambient conditions using simple mechanical stirring, providing scalable MCCS inventory to enable (i) continuous delivery of high-purity CO 2 (1437 millimoles over 200 minutes) from a laboratory-scale integrated system and (ii) direct electroreduction to carbon monoxide (CO) with a faradaic efficiency (FE CO ) of 51% without CO 2 supply. More broadly, it establishes a porous-liquid, interfacial-regeneration paradigm that decouples capacity from stoichiometry and enables electrified, continuous CO 2 capture, regeneration, and utilization under scalable, low-temperature conditions.

Efficient photocatalytic CO 2 reduction is limited by rapid carrier recombination and sluggish interfacial kinetics. Here, NiFe-LDH/ZnCdS (ZCS) heterostructures were fabricated by hydrothermal synthesis followed by electrostatic self-assembly. Mott–Schottky analysis, XPS, photoelectrochemical measurements, and density functional theory calculations collectively reveal staggered band alignment and interfacial charge redistribution, supporting a type-II charge-transfer pathway with improved carrier separation. The optimized 15NiFe-LDH/ZCS produced CO, CH 4 , C 2 H 4 , and C 2 H 6 at 16.54, 8.30, 1.22, and 4.70 μmol g −1 h −1 , respectively, while maintaining stable activity over 16 h. The enhancement originates from intimate interfacial contact, stronger visible-light harvesting, faster charge transport, and increased accessible active sites. These results establish a practical heterostructure-design strategy for multi-electron photocatalytic CO 2 conversion.

Carbon capture with chemical absorption method represents a critical pathway toward carbon neutrality in industry. However, its application faces challenges including high capture energy requirement for CO 2 desorption and limited CO 2 utilization routes. This study employed diethanolamine (DEA) as a CO 2 absorbent to prepare CO 2 –absorbed DEA (termed DEA–CO 2 ) with different CO 2 absorption amount. DEA–CO 2 was employed to modulate cement strength development, bypassing the energy-intensive CO 2 desorption step. Effects of DEA–CO 2 on cement hydration and the microstructure of the hardened cement pastes were investigated to reveal the regulation mechanism by in-situ carbonation. Results demonstrate that DEA-CO 2 additions show the potential to enhance 3d and 28d strength. Optimal performance occurs with 0.15% DEA and 0.22% CO 2 (D0.15%C0.22%), elevating 3d and 28d compressive strength by 15.3% and 29.3%, respectively. The enhancement is attributed to the accelerated hydration of aluminates and silicates by DEA–CO 2 to achieve a more condensed structure. Moreover, carbonation in cement pastes by DEA–CO 2 effectively mitigates the retardation effect of 0.15% DEA on early cement hydration. However, in the presence of DEA–CO 2 , the accelerated reaction of C 3 A with gypsum delays C 3 S hydration, especially for D0.15%C1.32%. It is hypothesized that the precipitated CaCO 3 or CaCO 3 –AFm on the surface of cement particles also inhibits further silicates hydration. Therefore, D0.15%C1.32% reduces the compressive strength before 28d. These results confirm the potential of utilizing DEA–CO 2 without desorption to optimize the strength development of cementitious materials, provided that the CO 2 dosage is carefully controlled.

Photocatalytic CO2 reduction offers a green strategy to alleviate climate change and address the energy crisis. In this work, indium oxysulfide subnanocoils with a thickness of 0.9 nm were successfully synthesized via a facile solvothermal method. Adjusting the sulfur content not only modulates the band structure and energy level positions but also enables precise control over the morphology of the as-prepared products. The optimized indium oxysulfide subnanocoils exhibit excellent photocatalytic activity for CO2 reduction, with a CO evolution rate of 61.731 μmol h–1 g–1, which ranks among the best performances for indium-based materials reported to date. The enhancement of photocatalytic performance can be attributed to the exceptionally high surface atomic exposure ratio of the unique subnanometer coiled structure. Meanwhile, the sulfur substitution-induced S–O coordination significantly reduces the average valence state of indium, narrows the band gap, and improves the reduction capability of photogenerated electrons. This study provides a feasible approach for the development of high-performance subnanoscale photocatalysts for CO2 reduction.

Electroreduction of carbon dioxide (CO2) to produce multicarbon products (C2+) holds immense potential for reducing carbon emissions and realizing high-valued CO2 utilization. However, the development of efficient catalysts still remains challenging. Cuprous oxide (Cu2O) has been identified as a promising candidate, yet its C2+ selectivity and stability require further improvement. In this study, we, for the first time, blended Cu2O with cerium oxide (CeOx) nanoparticles, forming a Cu2O/CeOx hybrid catalyst which greatly enhanced the selectivity and durability for C2+ production. The optimized catalyst achieved a remarkable carbon product Faradaic efficiency (FE) of 79.6% and a C2+ product FE of 58% (±2.4%) in an H-type electrolytic cell. Our findings provide a novel strategy for significantly improving the selectivity, efficiency, and catalyst stability of CO2 electroreduction.

We report herein the typical conductive polymer poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) to be successfully modified onto single-walled carbon nanotubes (SWCNTs) using a supercritical carbon dioxide (SC CO2) antisolvent-induced polymer epitaxy method, and the role of the experimental temperature of SC CO2 on the modification process was systematically investigated. PEDOT:PSS/SWCNTs composites with optimal modification prepared at 80 °C and 15 MPa were used as functional fillers, and functional temperature-sensitive composite hydrogels of PEDOT:PSS/SWCNTs/poly-N-isopropylacrylamide (PNIPAM) were successfully prepared. With the help of Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction, transmission electron microscopy (TEM), scanning electron microscopy (SEM), and other characterization means, the chemical composition and microscopic morphology of the composite hydrogel were systematically analyzed. The composite hydrogel exhibits reversible temperature-sensitive responsiveness, transitioning from a transparent swollen state at room temperature to an opaque collapsed state at 32 °C, and demonstrates strong adhesion to various substrates, including glass, plastic, metal, and skin. Meanwhile, the near-infrared (NIR) photothermal conversion properties of this hydrogel were evaluated, showing a significant and uniform temperature increase upon NIR irradiation. The drug release behavior was assessed in vitro after loading the hydrophilic anticancer drug 5-fluorouracil (5-FU) with the stimulation of NIR light, achieving an accelerated and on-demand release. Our experimental results indicate that the pore size increases with the increase of the addition of PEDOT:PSS/SWCNTs, enabling the precise controlled release of 5-FU. This work provides new insights and experimental support for the design of intelligent drug delivery systems.

Phase-separating absorbents show promise for reducing energy consumption, as desorption requires heating only the CO 2 -enriched phase. This study investigates triethylene glycol monobutyl ether (TGBE) as a phase-separation promoter for the N-methylaminoethanol (MAE)–water system. The role of TGBE in restructuring hydrogen-bond networks and promoting rich-phase aggregation was analyzed using gas–liquid–liquid equilibrium, 13 C NMR, gas chromatography, and molecular dynamics (MD) simulations. Experimental results demonstrate that TGBE significantly reduces rich-phase volume while achieving CO 2 equilibrium loadings of 3.59 mol/kg for water-containing systems and 4.73 mol/kg for water-free systems. MD simulations reveal that CO 2 absorption redistributes intermolecular interactions, where strengthened hydrogen bonds between water and ionic species drive polar rich-phase aggregation. Furthermore, an empirical model, a GBDT-based predictive model, and a modified Deshmukh–Mather framework were developed to describe phase behavior with AARDs of 2.81%, 4.58%, and 6.61%, respectively. These findings provide a theoretical foundation for designing energy-efficient CO 2 capture systems.

Indirect mineralization is a promising technology for carbon capture, utilization, and storage that enables CO 2 sequestration while simultaneously producing high-purity CaCO 3 . There remains a research gap in the regulation of the CaCO 3 product in the CO 2 mineralization process. This work innovatively compared CO 2 mineralization in different systems. Ca leaching from titanium gypsum was conducted using ammonium citrate, and then CO 2 mineralization was performed in Ca-rich solution (CRS) and calcium citrate precipitate (CCP) systems. The effects of key parameters including ammonia dosage, CO 2 flow rate, and temperature were studied, and the mineralization conversion rate and mineralization products were investigated. Ammonia dosage significantly influenced the mineralization conversion rate and the crystal form of CaCO 3 , and the conversion rate was 95% at 50 mL/L ammonia for CCP and 85% at 100 mL/L ammonia for CRS. Notably, increasing ammonia dosage promoted the vaterite formation in the CCP system. Temperature exhibited a pronounced impact on the mineralization conversion rate. As the temperature increased, the time required to attain the maximum conversion rate decreased markedly from 20 min to 5 min for CRS and from 60 min to 10 min for CCP. Temperature also influenced particle size and morphology, with both systems producing larger particles at higher temperatures. As to the growth mechanism of CaCO 3 , the CRS exhibited a gas–liquid interface dominated by homogeneous nucleation, while the CCP system proceeded through a gas–liquid–solid mechanism governed by heterogeneous nucleation. The high-quality CaCO 3 product (93.53% purity and 96.40% whiteness for CRS; 95.32% purity and 97.80% whiteness for CCP) meeting the standards of commercial CaCO 3 indicated promising economic benefits.

“Bimetallic-molecular” interface strategy constructs CuxAg1-x-SPyz catalysts for efficient CO 2 -to-methanol. • Cu 0.3 Ag 0.7 -Spy 0.05 achieves 46.8% methanol FE and 117 mA cm −2 partial current in a flow cell. • DFT calculations confirm Cu-Ag optimizes *CO adsorption, while pyridine modification lowers the *CO → *CHO barrier by 0.27 eV. The design of highly selective catalysts for direct methanol production via CO 2 electrolysis remains challenging due to its complex pathways and intense hydrogen evolution competition. This study employed a “bimetallic-molecular” interface synergy strategy to construct Cu x Ag 1-x -SPy z catalysts by in situ anchoring mercaptopyridine on the CuAg bimetallic surface. Experimental results indicate that the Cu 0.3 Ag 0.7 -Spy 0.05 catalyst in an H-cell exhibits a maximum Faradaic efficiency (FE) of 45.3% for methanol at −1.13 V (vs. RHE), while the FE for methanol in a flow cell reached 46.8% with a partial current density of 117 mA cm −2 , outperforming unmodified Cu Ag and existing mainstream catalysts. In situ ATR-FTIR spectroscopy simultaneously captured *COOH, *CO, *CHO, *OCH 2 , and *OCH 3 intermediates. Combined with DFT calculations, it was confirmed that Cu Ag synergistically optimized *CO adsorption energy, while the modified pyridine acted as a proton relay, lowering the *CO → *CHO energy barrier by 0.27 eV to achieve directional regulation of the methanol pathway. This study establishes a scalable molecular interface engineering paradigm for highly selective CO 2 methanolation and expands novel approaches to “metal-ligand” synergistic design in complex multi-electron reactions. Anchored by metal‑sulfur bonds, a mercaptopyridine modified copper‑silver bimetallic composite material Cu 0.3 Ag 0.7 -SPy 0.05 is prepared. The synergistic interaction between silver and copper bimetallic sites enhances the generation and adsorption of *CO, while the pyridine groups accelerate the effective protonation of *CO to methanol. It delivers a Faradaic efficiency of 46.8% with a partial current density of 117 mA cm −2 for methanol. Download: Download high-res image (179KB) Download: Download full-size image

ZIF-67-derived Co 3 O 4 /MXene Schottky heterojunction is constructed successfully. • MXene concentrates CO 2 molecules and participates in surface redox reactions. • Schottky heterointerface improves photogenerated carrier separation. • Co 3 O 4 /MXene Schottky heterojunction achieves effectively photocatalytic CO 2 reduction to CO. The escalating emission of carbon dioxide necessitates the urgent development of efficient CO 2 conversion technologies. Herein, a novel Co 3 O 4 /MXene Schottky heterojunction photocatalyst was rationally designed and synthesized, where Co 3 O 4 is derived from ZIF-67 and anchored onto MXene nanosheets. The composite demonstrates high activity in photocatalytic CO 2 reduction, achieving a yield rate of 58 μmol g −1 h −1 for CO using triethanolamine (TEOA) as an electron donor, while maintaining excellent stability over multiple cycles. The enhanced performance stems from the Schottky junction between Co 3 O 4 and MXene, which establishes a built-in electric field that drives efficient charge separation and directional carrier flow. Additionally, MXene acts as a cocatalyst that not only concentrates CO 2 molecules near active sites but also participates in surface redox reactions. This work offers an effective strategy for designing high-performance photocatalysts for sustainable solar fuel production.

High thermal stability amine solvents are critical for post-combustion CO 2 capture. For this, two novel ternary blended amine systems, AMP-AEP-MDEA and AMP-HMDA-MDEA were developed to overcome the limitations of traditional monoethanolamine (MEA) due to its poor thermal stability. The results demonstrated that both the chosen ternary systems exhibited superior CO 2 absorption-desorption performance compared to 30 wt% MEA due to synergistic kinetic effects and high molar amine density, emphasizing the importance of environmental management. To rigorously evaluate long-term durability, accelerated thermal degradation tests were conducted at 150 °C for 28 days to demonstrate AMP-AEP-MDEA had the highest thermal stability with a degradation rate of 25.1%, significantly lower than those of AMP-HMDA-MDEA (29.4%) and MEA (39.6%). Mechanistic investigations using 13 C NMR and GC-MS elucidated distinct degradation pathways. AMP undergoes independent intramolecular cyclization to form oxazolidinones, while stability of the activators dictates the overall system robustness. Rigid heterocyclic nature of AEP that restricts deep fragmentation, limiting the degradation of the side-chain cleavage. In contrast, flexible linear HMDA chains are susceptible to C-C bond breakage and dehydrogenation, leading to the formation of irreversible aromatic byproducts such as methylpyridine. The research highlights the critical role of molecular topology in solvent stability, suggesting AMP-AEP-MDEA as a promising candidate for large scale CO 2 capture to provide clean environment.
