Recently, researchers attempted to produce energy and chemicals via the electro-, thermo-, and photocatalytic conversion of CO₂ to realize sustainability and carbon neutrality. However, owing to the high thermodynamic stability of CO₂, these approaches are not yet ready for implementation in large-scale applications owing to their insufficient activities and selectivities and the stabilities toward resulting hydrocarbons. Therefore, more effective catalysts should be designed to transform CO₂ into various compounds. Porous crystalline frameworks, such as metal-organic frameworks (MOFs), are promising for use in catalytic CO₂ conversion, owing to their strong CO₂ adsorption capacities, high surface areas, high porosity and chemical compositions, and adjustable active sites.

Here, N/O coupled topological defect co-doped biochars (NWBCs-T) were successfully synthesized via self-assembly temperature-controlled carbonization/annealing within 500–900 °C from red bayberry pits. The influence mechanism of temperature on the formation, transformation, and interaction of N/O and pentagonal topological defect functionalities, as well as their impact on CO₂ adsorption, was systematically investigated. The results revealed that NWBC-900 exhibited the highest CO₂ adsorption capacity of 60 mg/g, primarily attributed to the prominent synergistic effect between N/O active sites and topological defect, rather than the physical adsorption force from micro-mesoporous pores, as evidenced by relevant analyses and Pearson heatmaps. Notably, the presence of pentagonal topological defects exerts a profound enhancing effect on CO₂ adsorption of edge graphitic-N and C-O-C sites, yet exerts weaker or opposite effects on other N/O configurations. Further insights from XPS and NMR analyses indicated a notable surge in pentagonal topological defects at elevated annealing temperatures, along with a reduction in total and pyrrolic nitrogen content. DFT calculation findings confirmed that pentagonal topological defects introduced at elevated temperatures adjust electron distribution, thereby facilitating improved electron transfer and boosting adsorption binding of NWBC-900 for CO₂.

This study employs a high-pressure, low-temperature microfluidic system to investigate hydrate formation and propagation during CO₂ injection in porous media. This approach enables direct visualization of pore-scale and chip-scale hydrate formation dynamics across thousands of pores, offering critical insights into large-scale submarine CO₂ storage processes. We systematically assess the effects of injection rate, temperature (1.1–9.4 °C), and pressure (6.9–13.8 MPa) on hydrate formation kinetics. CO₂ injection reduces spatial stochasticity, with nucleation occurring primarily near the injection zone due to localized subcooling. Hydrate propagation follows a cascade mechanism over a broad saturation range (9–94%). Two key parameters—induction time and propagation velocity—are identified: induction time decreases with higher injection rates, while propagation velocity remains stable. Propagation velocity follows a power-law dependence on subcooling (exponent=2) but is diminished in porous media due to the effects of tortuosity and CO₂ saturation degree. Pressure variations have minimal influence on hydrate growth, confirming that subcooling is the dominant factor controlling hydrate formation kinetics. Our findings suggest potential injection strategies for CO₂ storage as hydrates in submarine environments.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"15 ","pages":"Article 100401"},"PeriodicalIF":0.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143686271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A HDAC plant with an annual capture capacity of 3000 tonne CO₂ per year is modeled and life cycle impacts assessed for two locations (California and Louisiana) considered as potential deployment sites. The system is powered solely by electricity and is heat integrated across major sources and sinks in order to increase efficiency. A range of deployment scenarios are considered, varying both electricity source and the operational performance of the plant. Five electricity sources are considered based on the maturity of the electricity production processes and the practicality of their use at the chosen sites. The aim of this study is the evaluation of the viability of these potential deployment scenarios based on assessed life cycle impacts. In the majority of the deployment cases, electricity production dominates the global warming impacts related to capture, compression and sequestration of CO₂. The impacts related to non-electricity contributions are also explored, where it is found that the construction materials of the plant can have a notable impact in sufficiently decarbonized electricity scenarios. Sorbents are shown to have a minimal impact (carbon burden about 1 %) in agreement with previous studies. Significant net removals of CO₂ from the atmosphere are found for all scenarios considered with the carbon burden for full plant operation (capture to sequestration) ranging from 3.5 % to 64.0 % dependent mainly on the carbon intensity of the power source. A broader environmental impact assessment suggests no immediate concerns when selecting between nuclear, wind or solar power for plant operation.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"15 ","pages":"Article 100403"},"PeriodicalIF":0.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143686273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cu-Zn and Fe-Cr catalysts are used in industry for this reaction at low temperatures (LT) and high temperatures (HT), respectively.

A novel trinuclear tetradentate Schiff base chromium complex <strong>1</strong> was designed and synthesized, and combined with bis(triphenylphosphine) imidazolium salt (PPNN₃) to form a binary catalytic system (complex <strong>1</strong>/PPNN₃). This system was employed to catalyze the copolymerization of CO₂ with bicyclic epoxide compounds containing both terminal and internal epoxy groups (VCHDEP). Experimental results demonstrate that a bifunctional polycarbonate (PVCH) was efficiently synthesized through a simple one-step process, featuring a polycarbonate cyclohexene ester backbone with side chains containing both epoxy (EP) and cyclic carbonate (CC) groups. The EP/CC ratio can be precisely tuned by varying the reaction temperature and the molar ratio of PPNN₃, enabling control over polymer properties. Notably, the glass transition temperature (Tg) of PVCH was found to be 164.5 °C, significantly higher than that of conventional polycarbonates synthesized from bisphenol A (154 °C), indicating superior thermal stability and mechanical robustness. The complex <strong>1</strong>/PPNN₃ catalytic system selectively catalyzed the ring-opening copolymerization of epoxides to form the polymer backbone, while retaining unreacted epoxy groups in the side chains. In this catalytic system, the enthalpy change (ΔHₚ^θ) for the VCHDEP ring-opening polymerization is -20.5 kJ mol^-1, the entropy change (ΔSₚ^θ) is -80.3 J mol^-1 K^-1, the Gibbs free energy change (ΔGₚ^θ) is 3.5 kJ mol^-1, and the activation energy (Ea) for PVCH synthesis is 56.8 kJ/mol. Furthermore, hydrolysis and amination reactions were performed on the cyclic carbonate and epoxy groups in PVCH, yielding polycarbonates with hydroxyl, amide, and other functional groups, which further enhance the material's versatility for applications requiring strong adhesion, biocompatibility, and chemical reactivity.

However, the high viscosity of the CO₂-rich phase after phase separation often leads to challenges such as increased flow resistance, reduced heat transfer efficiency, and instability of phase separation. To address these issues, this study proposes a novel phase-change capture system comprising AEEA-DEHA-H₂O (AEEA: 2-(2-aminoethylamino)ethanol, DEHA: N, N-diethylhydroxylamine). The experimental results revealed that a biphasic absorbent composed of 30wt% AEEA, 40wt% DEHA, and 30wt% H₂O achieved an absorption capacity of 0.93 mol CO₂·mol⁻¹ amine, with a desorption efficiency of 75.3 % at 110 °C and a viscosity of 58 mPa·s after saturation at 40 °C. The energy consumption of this system was 20.5 % lower than that of the conventional MEA solvent. Quantum chemical calculations indicated that the hydroxyl group in the DEHA structure was directly bonded to the nitrogen atom, which enhanced the hydrophilicity of the system. This structural feature allowed DEHA molecules to form strong hydrogen bonds with water, thereby increasing their water solubility and reducing the viscosity of the system. Furthermore, the strong affinity of AEEA-derived products for other CO₂ capture products and H₂O resulted in their aggregation into a CO₂-rich phase. In contrast, the relatively low polarity of DEHA led to a weaker affinity for AEEA-derived products, allowing DEHA to separate from the solution and form a CO₂-lean phase.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"15 ","pages":"Article 100392"},"PeriodicalIF":0.0,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143562623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
