Polymers are promising materials but show insufficient ion transport properties, a limitation that can be lifted by the fabrication of composite polymer electrolytes. Nevertheless, the role of the inorganic particles in tuning the conduction properties is often unclear, especially when inert fillers are added. Herein, poly(trimethylene carbonate) and alumina particles: α-Al2O3, γ-AlOOH and γ-Al2O3 are mixed by two dispersion methods to prepare a series of composites. The correlations between microstructure, surface chemistry, and transport properties are studied, which are evaluated by combining synchrotron nanotomography, solid-state nuclear magnetic resonance, and electrochemical impedance spectroscopy, respectively. An increase of the conductivity by a factor of 1.9 ± 0.6 (1.4 ± 0.4) is observed for α-Al2O3 (γ-AlOOH) while no beneficial effect of dispersion is seen for γ-Al2O3. It is found that dispersion of the particles is crucial, with an interfacial area between polymer matrix and inorganic fillers increased by a factor of 1.3-3 when the particles are dispersed. Moreover, the density of surface groups is estimated at the interface and correlations are found to the changes in conductivity, showing that interactions at the interface of the particles are one key parameter driving the composite performance.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2402709"},"PeriodicalIF":6.6,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144990962","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}

In order to improve its working potential, a new insoluble small-molecule organic cathode named 1,7-dicyano-perylene-tetracarboxylic dianhydride (PTCDA-2CN) is designed and synthesized with two electron-withdrawing groups cyano bonds (-CN). As expected, PTCDA-2CN can exhibit the high working potential ≈2.8 V (vs. Li) with its decreased lowest unoccupied molecular orbital energy, which is ≈0.3 V higher than PTCDA. And the introduction of two -CN groups can maintain the basis CT value of 121 mAh g-1 for PTCDA-2CN. Consequently, PTCDA-2CN exhibits the good cathode performances in Li-ion half/full cells. In half cells, PTCDA-2CN can show the discharge capacities of 117-107 mAh g-1 with the stable cycling retention of 91% during 100 cycles. Meanwhile, using the reduced state (LiC6) of graphite (C) as the anode, the LiC6//PTCDA-2CN full cells can also exhibit good performances of 116-98 at 50 mA g-1 with the high median voltage of 2.7 V.

Although the degradation of MnO2 cathodes has been extensively investigated, the underlying reaction mechanisms have long remained a subject of debate, and the associated mechanical evolution during cycling is still poorly understood. In this work, a comprehensive investigation of electrochemical phase transitions and chemical strain evolution in δ-MnO2 cathode is presented using a custom-built in situ strain testing system based on digital image correlation. The results reveal that the discharge-charge mechanism of δ-MnO2 proceeds through initial cointercalation of H+ and Zn2+ causing elastic deformation, followed by phase transformation to ZnMn2O4. During charging, this phase transformation coupled with ZnMn3O7 formation induces irreversible plastic deformation, generating substantial residual strain and cathode volume expansion. Increasing current density can effectively reduce residual strain by suppressing phase transformation, thereby enhancing electrode cycling stability.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501270"},"PeriodicalIF":6.6,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144990906","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}

A combination of zeolites with photocatalytic materials can address this issue by oxidizing adsorbed VOCs from the zeolite surface to CO2 gas under light irradiation. Herein, the in situ formation of photocatalytic active defect-rich graphene is presented on a commercial zeolite surface (ZSM-5) when properly dealuminated ZSM-5 is exposed to an acetaldehyde/humid air mixture under visible light. This in situ photocatalytic activation occurs when a critical amount of local surface coverage of acetaldehyde and water molecules is achieved on a dealuminated zeolite surface under visible light. The findings not only provide a deeper understanding of VOCs removal by zeolite but also suggest a new and simple approach to enhancing the performance of zeolite for VOCs removal through the combination with a photocatalytic material.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2501165"},"PeriodicalIF":6.6,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144990910","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}

Herein, a host-guest strategy is reported for engineering metal-organic frameworks (MOFs) through the encapsulation of conductive polymers to stabilize reticular skeletons and regulate interfacial water for efficient CO2-to-CH4 conversion. Specifically, polypyrrole (PPy) and polyaniline (PANI) are confined within Cu-anchored UiO-67 frameworks, resulting in hybrid catalysts-PPy@Cu-UiO-67 and PANI@Cu-UiO-67-with preserved crystallinity and enhanced electronic conductivity. Among them, PANI@Cu-UiO-67 exhibits superior CH4 Faradaic efficiency (FECH4 up to 71.1%), outperforming PPy@Cu-UiO-67 and unmodified Cu-UiO-67. Spectroscopic analysis reveals that the polymers reinforce structural integrity and induce distinct perturbations in the interfacial water network. In situ Raman and attenuated total reflection surface-enhanced infrared absorption spectroscopy measurements identify the dominance of weakly hydrogen-bonded water (2-HB·H2O) at the PANI-modified interface, which supports rapid proton transfer while suppressing HER. This study offers a rational design strategy for MOF electrocatalysts by integrating conductive polymers to modulate both the electronic and interfacial environments for high-efficiency methane production.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501318"},"PeriodicalIF":6.6,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937345","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}

The main roadblocks of current plastic recycling technologies include low-quality recycled plastics and inefficient degradation under harsh conditions, which highlights the urgent need to develop efficient and sustainable recycling processes. Herein, for the first time, a strategy is developed using bio-based solvent dihydrolevoglucosenone (Cyrene) for efficient recycling of waste PET-to-polymer or monomer. In this study, Cyrene effectively dissolves PET at 165 °C within 20 min. Furthermore, PET dissolved in Cyrene and regenerated by ethanol as an antisolvent, exhibiting excellent chemical and thermal stability with minimal degradation. Cyrene also functions as a cosolvent for the alkaline hydrolysis of PET, resulting in ≈100% PET degradation to terephthalic acid (TPA) with a yield of 98.2% within 18 min at 80 °C. The presence of Cyrene enhances the interface compatibility between PET and solvent, while the hydroxyl groups in EG form hydrogen bonds with Cyrene, facilitating the interaction between PET and NaOH. Overall, this study contributes to the advancement of solvent-based recycling strategies for the cost-effective recovery of PET waste.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501352"},"PeriodicalIF":6.6,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937214","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}

Herein, a flexible solid-state polymer skeleton employed with ionic liquid and metal-organic frameworks (PIM) electrolyte is proposed to strengthen interfacial Li ion exchange by improving the Li+ sieving effect and interfacial wettability. Thanks to the immobilization effect of TFSI- anions affected by positive metal atom centers and pore morphology, the PIM electrolyte exhibits exceptional properties, i.e., a high ionic conductivity up to 3.1 mS cm-1 at 60 °C and an improved Li+ transference number of 0.65, enabling symmetric cells of Li metal to run steadily for over 1000 h with lower voltage hysteresis (25 mV). Meanwhile, matching with high-voltage electrodes, the solid-state PIM electrolyte exhibits good compatibility and stability toward LiNi0.6Co0.2Mn0.2O2 and LiFePO4 electrodes, showing the capacity retentions of 85.5% and 96.5% after 120 and 400 cycles, respectively.
