Here, we report a tandem-catalyzed strategy for the mild step-growth polymerization of a fatty acid-derived monomer into high-molar-mass aliphatic polyanhydrides. Selective ruthenium-catalyzed self-metathesis of 10-undecenoic acid affords eicos-10-enedioic acid with high conversion and minimal olefin positional isomerization within the substrate. The resulting diacid is subsequently converted into a polyanhydride through magnesium-catalyzed dehydrative polycondensation using dimethyl dicarbonate as a stoichiometric dehydrating reagent. The two catalytic transformations are operationally compatible and can be performed as a sequential one-pot process without isolation of the diacid intermediate. The orthogonal Ru/Mg sequence affords polyanhydrides with weight-average molar masses above 30 kg/mol, while the independently optimized magnesium-catalyzed polymerization reaches weight-average molar masses above 80 kg/mol. A ruthenium species derived from the metathesis catalyst can also promote the dehydrative coupling step, providing an auto-tandem pathway, although with lower molar-mass control. The resulting polyanhydride films exhibit water contact angles of 95°–100°, within the range reported for polyethylene and polypropylene surfaces. This work establishes a mild and step-efficient route from a renewable unsaturated fatty acid to hydrophobic aliphatic polyanhydrides.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 21","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cssc.71206","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149331841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The catalyst was prepared via wet impregnation of presynthesized Cu–Zn species into the metal-organic framework (MOF). Batch tests under mild temperatures and low CO2 concentration showed that the MOF-based system achieved higher methanol yields than a commercial catalyst at 150 °C. Step-response experiments in a plug-flow reactor revealed that the MOF retained a significant amount of CO2 under high-pressure and dynamic conditions. In situ diffuse reflectance infrared Fourier transform spectroscopy identified methanol-related surface intermediates, while ex situ postreaction 1H nuclear magnetic resonance spectroscopy supported the formation and retention of methanol and oxygenated species in the MOF-based catalyst. X-ray absorption spectroscopy showed partial reduction of oxygenated Cu species during reaction, while in situ X-ray diffraction demonstrated structural stability of the Mg2(olz) MOF framework.

Electrons and hydrogen atoms emerge as the dominant agents of defluorination, while hydroxyl radicals play a secondary role. Coupled with experimental validation in a nonthermal plasma reactor, we demonstrate that electron upconversion facilitates catalytic defluorination cycles through radical–anion cross-reactions, enhancing fluoride release up to four-fold.

We summarize how in situ Raman and Fourier transform infrared spectroscopy enable real-time identification of adsorbed intermediates and active species, providing mechanistic insights inaccessible to ex situ methods. We then evaluate noble-metal and non-noble-metal catalysts and discuss how their structural characteristics regulate EG adsorption, OH− activation, and intermediate conversion.

We further survey EGOR applications in electrolysis systems, including pairing with hydrogen evolution for coproduction of value-added chemicals and hydrogen and coupling with CO2 reduction or organic synthesis to construct energy-efficient electrochemical cells.

Herein, we investigate how functional group chemistry influences Li/Li+ interactions, dissolution behavior, interfacial evolution, and electrochemical accessibility in naphthalene-derived organic anodes. Using naphthalene as a model framework, we systematically compare hydroxylated and carboxylated derivatives through combined computational, electrochemical, spectroscopic, and morphological analyses. Density functional theory (DFT) calculations reveal stronger localized Li+ interactions at the vicinal dihydroxyl groups of 2,3-dihydroxynaphthalene (DHN) and the carboxyl group of 2-naphthoic acid (NPA) than in Naph and the monohydroxylated derivatives. However, this enhanced local affinity does not translate into improved electrochemical reversibility. Naphthalene and the monohydroxylated derivatives exhibit limited dissolution, relatively stable interfacial behavior, and sustained cycling performance over 1000 cycles. In contrast, DHN and NPA exhibit greater active material dissolution and more extensive interfacial reconstruction, resulting in reduced electrochemical accessibility and inferior reversibility. This work highlights the importance of balancing favorable Li/Li+ interactions with resistance to dissolution and interfacial reconstruction to preserve electrochemically accessible active material in small-molecule organic anodes.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 21","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cssc.71197","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149310872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the OA side chains further improved thermal insulation through increased phonon scattering and latent heat absorption, collectively contributing to excellent infrared stealth and thermal protection.

Through systematic electrolyte engineering, the bottlenecks of electrochemical performance and electrolyte viscosity are simultaneously addressed. Specifically, redox targeting is introduced to boost cathode kinetics, with trace additives concurrently suppressing anodic hydrogen evolution, enabling a 10 wt% Fe/Ni achieves an energy density boost from 3 to 21 Wh L−1, along with stable operation for 100 cycles.
