In this work, ZnCdS was anchored on the surface of CoSx by in-situ hydrothermal method, thereby constructing a ZnCdS/CoSx ohmic heterojunction and achieving directional electron transfer from ZnCdS to sulfur rich CoSx. Among them, CoSx was modified by sulfur enrichment and amorphization. The modified CoSx can expose more S active sites, effectively weaken S-Hads bonds, and promote the desorption process of hydrogen gas. In addition, after the formation of heterojunctions, the broad spectral response of CoSx can effectively enhance the visible light absorption ability of ZnCdS, improve the utilization of visible light, and facilitate the hydrogen evolution reaction (HER) process. Specifically, ZnCdS/CoSx-20 exhibits a significant hydrogen evolution rate of 28.4 mmol g-1 h-1 under visible light irradiation, which is approximately 9.8 times that of pure ZnCdS (2.9 mmol g-1 h-1). Density functional theory (DFT) calculations indicate that a significant negative shift in the d-band center in ZnCdS/CoSx heterojunctions, which is beneficial for the weaken S-Hads bond and desorption process of hydrogen gas. In situ XPS further confirm the charge transfer direction and prove increase surface charge density of CoSx. This work provides new insights into the design of ZnCdS based heterojunctions to achieve effective charge transfer.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"30 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143723289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, water−induced side reactions and dendrite growth severely compromise the stability of zinc−ion batteries. Moreover, it remains challenging to prepare both tough and recyclable hydrogel electrolytes. This work developed tough and recyclable borate−crosslinked polyvinyl alcohol (PVA/borax/ZnCl2) composite hydrogels through a one−pot method. These hydrogels were engineered through dynamic chemical crosslinking and entanglements of PVA chains induced by partial dehydration, with continuous ion migration pathways. Borax not only plays an important role in chemical crosslinking but also regulates the solvation structure of hydrated Zn2+. The strong interactions between PVA and free water effectively reduced water molecule activity, and thereby, side reactions were suppressed. Additionally, these hydrogel electrolytes exhibited excellent environmental adaptability, mechanical robustness, self−adhesiveness, recyclability, and self−regeneration. The Zn||Zn symmetric batteries displayed stable performance at both −20 and 25 C (1500 h of cycle life at 2 mA·cm−2) even after recycling (1000 h of cycle life at 2 mA·cm−2), without dendrite growth or side reactions.

However, the slow oxygen reduction reaction (ORR) at the cathode, especially at intermediate-low temperatures, poses a critical challenge to the development of MS-SOFCs. Here, we report a synergistic effect of co-doping in a cation-ordered double perovskite type material, Sm(Ba0.5Sr0.5)Co2-xFexO5+δ (SBSCFx), which has enhanced catalytic activity for ORR and chemical compatibility with Ce0.9Gd0.1O2-δ (GDC). X-ray photoelectron spectroscopy and thermogravimetric analysis were used to examine how Fe-doping in SBSCFx impacts the functional properties. A composite cathode with GDC was further prepared to enhance thermal compatibility with GDC, which effectively reduces the thermal expansion of the SBSCFx cathode from 23.35×10-6 K-1 to 15.04×10-6 K-1. The electrochemical results of symmetrical cells and the DRT fitting analysis demonstrate that the SBSCFx-GDC composite cathode exhibits strong ORR activity. Notably, the SBSCF10-GDC composite cathode achieves a remarkably low polarization resistance of 0.05 Ω·cm² at 650°C. The metal-supported single cell with SBSCF10-GDC cathode exhibited an open-circuit voltage of 0.85 V and showed a peak power density of 833 mW cm-² at 650℃.

Since prior studies have focused on STF with Fe content x = 0.7, questions remain as to whether other compositions provide better stability and performance over a range of fuel compositions. The present study examines a wider composition range from x = 0.5 to 0.8. Furthermore, phase evolution during exposure to varying H2/H2O is observed in situ using x-ray diffraction and correlated directly with impedance spectroscopy observations of electrochemical characteristics and stability. All STF compositions exhibited good phase and polarization resistance stability in the perovskite structure for pH2/pH2O ratio of 1. However, decomposition occurred in more reducing fuels pH2/pH2O≥10, into Ruddlesden-Popper (R-P) Perovskite, Strontium Oxide, and metallic Fe, after an incubation time of ~ 2 – 4 h, the same time frame over which polarization resistance increased rapidly. That is, the results show a clear correlation between phase decomposition and rapid electrochemical degradation. The results suggest that the R-P transformed oxide was less electrochemically active despite the presence of exsolved Fe. Decreasing the Fe content x resulted in slower and reduced decomposition, but slightly higher initial polarization resistance values.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"41 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143723346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike conventional studies that assume uniform catalyst surfaces, this work systematically measured the interaction strength on different ZnO facets, using atomic force microscopy (AFM)-based force spectroscopy under conditions replicating the reaction environment. Interaction strengths among ZnO surfaces followed the order: O-terminated > Zn-terminated > mixed-terminated. The finding that ZnO powder, with polar Zn- and O-terminated surfaces, exhibited adsorption capacity approximately five times higher than that of ZnO nanorods, which have non-polar mixed-terminated surfaces, despite having an order of magnitude lower surface area further highlights the role of surface interactions in governing adsorption and subsequent photocatalytic performance. Stronger adsorption under acidic conditions enhanced the degradation efficiency, while alkaline conditions altered adsorption orientations and reduced the capacity. The degradation pathways were found to be highly facet- and pH-dependent, leading to distinct sets of intermediates with varying toxicity. Cytogenotoxicity assays revealed that certain degradation products formed under alkaline conditions were more harmful than diuron itself, underscoring the need for optimized photocatalyst designs. This work provides critical insights into facet-dependent interactions and pH effects, paving the way for more effective and safer photocatalytic solutions for environmental remediation.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"35 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a customized structural reconstruction strategy is developed to tackle the activity-stability paradox of IrOx electrocatalyst for acid water electrolysis. By tuning the structural reconstruction of NiCoIr alloy, a crystallized NiCo-IrOx catalyst with 3D nanoporous structure is obtained. At Ir loading as low as 0.62 mg cm-2, the NiCo-IrOx catalyst achieves a record low overpotential of 209 mV for oxygen evolution and 37 mV for hydrogen evolution to reach 10 mA cm−2. Negligible degradation is observed for operating over 100 h under the current density of 100 mA cm-2. The NiCo-IrOx catalyst showcases superior performance and considerable potential in proton exchange membrane (PEM) electrolyzer application. In situ analysis combined with theorical simulations reveals distinct modulation mechanism of Ni and Co on the reconstruction of Ir sites. The deployment of Ni primarily augments the exposure of active sites, while Co doping modifies the electronic structure of Ir sites, optimizes the adsorption energy of reaction intermediates and suppress the participation of lattice oxygen during oxygen evolution reaction. The coordination of Ni and Co balances the geometric and electronic effects, therefore enhances the activity and stability of the IrOx catalyst simultaneously.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"23 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, the recovery of valuable metal elements from spent batteries has become a current focus of research. In this study, deep eutectic solvents were employed as green leaching and precipitation agents to selectively separate lithium from nickel, cobalt, and manganese and synthesize MnaCobNiOx catalysts for the simultaneous removal of NO and benzene. The catalytic performance was optimized by controlling the manganese content. A key aspect of study is to explore the influence of lithium ion removal process on the catalytic material. Compared to catalysts synthesized from traditional metal salts, those derived from spent lithium-ion batterie demonstrates superior low-temperature reducibility, enhanced surface acidity, and richer surface-active oxygen species and oxygen defects due to the de-lithium and presence of trace lithium ions. During the simultaneous removal process, the catalyst exhibits over 90% denitrification efficiency in a wide temperature range of 100-270°C and achieves 90% benzene removal at 180°C. In situ DRIFTS results reveal that benzene adsorption occupied the Lewis acid sites of the catalyst, inhibiting the adsorption of NH3 and NO. Furthermore, the competitive utilization of active oxygen by NH3 and NO hinders the oxidation of benzene to intermediates, thereby preventing the formation of CO2 from benzene oxidation.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"27 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
