Currently, this reaction is catalyzed by transition metal molecular complexes, which show low activity, limiting their industrial application. Therefore, the development of highly active heterogeneous catalysts for this reaction is desirable. Herein, metal dimers introduced into graphene are assessed as heterogeneous catalysts for the CO2-ethylene coupling reaction using density functional theory calculations. It is found that Pd, Rh, Ni, and Cu dimers facilitate the βH transfer steps, whereas Zn, Ru, and Os facilitate the CC coupling steps. The variation of the overall energetic barrier based on the energetic span model is rather narrow, as these two elementary steps are anticorrelated with each other. Furthermore, the stability of metallalactones is found to be a key descriptor for the activation energies of both the CC coupling and the βH transfer steps. Using Crystal Orbital Hamilton Population analysis, it is identified that the strength of the CβCγ bond in metallalactones can serve as an electronic-level descriptor for activation energies. It is anticipated that the insights gained from this study will guide the development of heterogeneous catalysts for the CO2-ethylene coupling for producing acrylic acid.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501359"},"PeriodicalIF":6.6,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145068697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single-atom catalysts (SACs) with metal-nitrogen-carbon motifs have been transformative in electrocatalytic CO2 reduction (eCO2R), due to their high atomic utilization, undercoordinated active sites, and unique electronic structures. Herein, porous CNFs from three polymers, viz. Bacterial cellulose, Aramid, and Zylon, are optimally synthesized. The textural and porous architectures of the CNFs are exploited for ambient and high-pressure CO2 capture, with Aramid-CNFs exhibiting the highest CO2 adsorption capacity of ≈4 mmol g-1 at 1 Bar, 273 K. Subsequently, the N-doped CNFs of carbonized bacterial cellulose (N-CBC) are explored for hosting Ni single atoms to yield Ni-N-CNF SACs. Extended x-ray absorption fine structure (EXAFS) analysis, microscopic studies and corroborative density functional theory (DFT) calculations confirmed the atomic dispersion of Ni sites on N-CBC matrix having Ni-N4 coordination. Ni-N-CBC at a mere 0.1 wt% Ni loading exhibited competitive and durable eCO2R-to-CO performance with Faradaic efficiency (FECO) of 94 ± 3% at -0.53 V versus reversible hydrogen electrode (RHE) and a high turnover frequency (TOF) of 35.26 s-1.

After conversion to the hydroxide (OH-) form, membranes are characterized using gravimetric water vapor sorption, infrared spectroscopy, thickness variation measurements, and conductivity testing under controlled humidity. Results reveal that the chemical nature and spatial accessibility of the ionic group play a central role in modulating hydration, OH- mobility, and membrane performance. The FAA-3-50 membrane, with a rigid diazabicycle (DABCO)-based group, exhibits limited water uptake and pronounced conductivity hysteresis. In contrast, the A17 membrane, incorporating a more flexible piperidinium group, demonstrates enhanced hydration, lower hysteresis, and better retention of ionic conductivity under varying humidity. The findings underscore the impact of water-ionomer interactions on membrane dimensional stability and conduction mechanisms. Ultimately, the study provides insights into designing advanced AEMs through tailored ionic functionalities and controlled water management, essential for high-performance and durable AEM fuel cells, particularly under low-humidity or dynamically fluctuating conditions.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501604"},"PeriodicalIF":6.6,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145068748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many factors contribute to charge transfer, such as flexibility of the backbone, redox moiety type, and distance between neighboring redox sites. In a previous work, a series of spatially defined 2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPO)-containing polymers was reported, with varied spacer lengths between the redox sites. Herein, the synthesis and characterization of spatially defined polymers is reported with the same spacing of three different redox pendants (phenothiazine, phthalimide, and dopamine) and the corresponding electrochemical properties. By doing so, the effect of solution-polymer interactions (in both the charged and neutral states) is revealed. The apparent diffusion coefficient (Dapp), the self-exchange rate constant (kex), and the polymer-solvent interactions (χ and A2) of the phenothiazine, phthalimide, and TEMPO polymers are compared. The dopamine-based polymer exhibits limited solubility, preventing further characterization. Dapp and kex correlate with χ, suggesting that solvent favorability enhances charge transfer in the solution state. These findings highlight the important role that polymer-solvent interactions play in the transfer of electrons, suggesting that a swollen polymer chain conformation promotes solution-state electron transfer and that solvent favorability promotes charge transfer.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501121"},"PeriodicalIF":6.6,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145063008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biocatalytic methods are often presumed to be more sustainable alternatives to chemical approaches; however, their environmental and economic viabilities require critical evaluation. This review summarizes the recent advancements in natural product glycosylation and provides a comprehensive techno-economic and environmental assessment based on yield, titer, rate, environmental factor, and impact on endpoint categories using a life cycle impact assessment approach. Although biocatalytic methods are highlighted for their superior yields, they are frequently hindered by lower titers and reaction rates compared to their chemical counterparts. Surprisingly, chemical glycosylation exhibited lower environmental factors (E-factors), whereas biocatalytic approaches displayed lower impacts on endpoint categories, highlighting that E-factors fail to capture the environmental implications of a process. This review demonstrates the challenges associated with quantifying the environmental impacts of a process, especially given the lack of experimental detail reporting in the biocatalytic field. It exposes the misguided assumption that biocatalytic processes always exert lower environmental burdens and identifies key opportunities to enhance process efficiency and sustainability, providing guidance for selecting and developing a given natural product glycosylation reaction.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2501094"},"PeriodicalIF":6.6,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
