This study evaluates a series of A-site doped perovskite-type oxygen carriers, La0.8A0.2FeO3 (A = Ca, Sr, Ba), to investigate the influence of alkaline earth metal doping on redox behavior and catalytic performance in CL-SMR. Substituting divalent cations at the A-site effectively promotes oxygen vacancy formation and enhances lattice oxygen transfer. Among the evaluated oxygen carriers, Sr-doped LaFeO3 (La0.8Sr0.2FeO3) exhibits the most favorable performance. This is attributed to the optimal concentration of oxygen vacancies, which improved oxygen transfer, as confirmed by X-ray photoelectron spectroscopy, cerimetric titration, and O2-temperature programmed desorption. While undoped LaFeO3 (LF) exhibits the highest methane activation, its limited oxygen mobility leads to severe coke formation. Enhanced oxygen transfer in La0.8Sr0.2FeO3 effectively suppresses carbon deposition, while it shows the highest CO and hydrogen production. It achieves consistently high CO and H2 yields (6.22-6.51 and 6.48-6.69 mmol/gcat, respectively) and demonstrates excellent stability over 50 redox cycles.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501667"},"PeriodicalIF":6.6,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248973","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}

While positive electrodes containing elemental sulfur require a lithiated negative electrode, lithium-sulfide can serve as the lithium reservoir and thus be paired with bare copper electrodes in \"anode-free\" or \"zero-excess\" cell concepts. This boosts energy density and avoids handling of thin lithium metal electrodes. While promising electrochemical performance of \"anode-free\" lithium-sulfide batteries has already been demonstrated, many reported cell configurations rely on nickel- instead of copper-based negative electrodes, undermining the enhanced sustainability bestowed by lithium-sulfide positive electrodes. Demonstrating a continuous reaction between copper electrodes and soluble polysulfide species, two approaches are evaluated that restrict the migration of polysulfide species. While both, in situ polymerization of an electrolyte additive as well as electrospinning of a polymer layer at negative electrodes, enable reversible operation of copper-based \"anode-free\" lithium-sulfide batteries, the former approach offers notably enhanced capacity retention. Counterintuitively, the quantification of polysulfide distribution throughout the individual battery components reveals less confinement within the positive electrode as beneficial for the overall reversibility. This demonstrates that a balance between positive and negative electrode reversibility is required to advance \"anode-free\" lithium-sulfide batteries.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501104"},"PeriodicalIF":6.6,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249036","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}

However, the development of solid polymer electrolytes (SPEs) that simultaneously achieve high ionic conductivity, mechanical resilience, and interfacial stability remains a significant challenge. Although incorporating functionalized inorganic fillers into polymer matrices has shown partial success in enhancing ion transport, the intrinsic limitations of traditional fillers-low room-temperature ionic conductivity-hinder their further application. To address this, a novel strategy inspired by photocatalytic design principles is proposed, which involves engineering photocatalytic active fillers to generate strong and stable photogenerated electric fields. These fields modulate interfacial charge distribution, promote segmental motion of polymer chains, and facilitate lithium (Li) salt dissociation, while simultaneously optimizing the Li+ solvation structure and coordination environment. Importantly, this approach significantly minimizes anion recombination, effectively suppressing space charge layer formation and reducing Li+ concentration gradients.

Hence, a novel p-phenylenediamine substituted perylenediimide (pPDI)/nitrogen vacancy-modified carbon nitride (NV-CN) S-scheme heterojunction photocatalyst, integrated with pPDI polymers and NV-CN, is synthesized. The introduction of bridged p-phenylenediamine units in the pPDI skeleton creates a strong built-in electric field, which can significantly enhance the separation and migration of charge. Additionally, the constructed S-scheme system greatly facilitates the interfacial photogenerated carrier separation and transfer. Meanwhile, the introduction of nitrogen vacancies into NV-CN acts as an electron trap to capture electrons, thus preventing the recombination of electron-hole pairs and significantly prolongs N2 absorption capacity. Benefiting from these synergistic advantages, the optimized 10% pPDI/NV-CN heterojunction achieves a superior NH3 yield of 8.83 mM g-1 h-1, achieving 12.26 and 13.63 times increase over CN (0.72 mM g-1 h-1) and PDI (0.65 mM g-1 h-1), respectively.

A significant limitation of switchable hydrophilicity solvents is the slow rate of the switching process, which can lead to evaporative losses even of the nonvolatile solvent used as well as incurring a significant energy cost. The lengthy switching procedure can also affect the purity of compounds that possess poor thermal stability. This article details the use of a vortex fluidic device in both batch and continuous flow modes to enhance the efficiency of reactions between the amine switchable hydrophilicity solvent, water, and CO2, substantially reducing the required reaction time. The ability of the vortex fluidic device to enable the reverse switching process is tested and discussed, along with the implementation of a continuous flow methodology capable of substantially reducing switching times.

Coupling OEMs with nonvolatile solid electrolytes offers the possibility for improving the technological sustainability and inherent safety of rechargeable batteries. This report delves into the representative carbonyl-based OEM, lithium terephthalate (Li2C8H4O4, LTPA), and prevailing graphite anode, and systematically investigates their fundamental properties with polyether-based electrolytes utilizing two sulfonimide anions (i.e., bis(fluorosulfonyl)imide and bis(trifluoromethanesulfonyl)imide), aiming to elucidate the unique features of OEMs and its synergy with salt anions. Results show that LTPA suffers from poor electronic conductivity in polymer electrolytes, while parasitic side reactions and cointercalation of low-molecular-weight compounds handicap neat graphite materials. Surprisingly, blended composite electrodes comprising graphite and a small portion of LTPA exhibit higher Coulombic efficiency and better capacity retention over continuous cycles, with significant improvement in the electrochemical utilization degree of graphite. The synergy between OEMs and classic graphite electrode materials in polymer electrolytes may spur the architectural design of solid-state batteries, and promote the realization of more sustainable battery technology in the near future.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501549"},"PeriodicalIF":6.6,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230968","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}
