One strategy is accessing high voltage capacity through high-valent redox reactions. Such reactions usually cause instability in cathode materials, but Na<small><sub>2</sub></small>Mn<small><sub>3</sub></small>O<small><sub>7</sub></small> (NMO) has demonstrated excellent performance and reversibility in the high-valent regime due to its unique lattice structure with ordered Mn vacancies. This work expands the universality of the ordered vacancy as a design principle and increases the material candidates with such exceptional electrochemical behavior. Our approach involves synergizing cationic ordered vacancies with tunable metal-ligand hybridization through partial metal substitution. In particular, we successfully incorporated Fe<small><sup>3+</sup></small> for Mn<small><sup>4+</sup></small> in NMO to make Na<small><sub>2.25</sub></small>Mn<small><sub>2.75</sub></small>Fe<small><sub>0.25</sub></small>O<small><sub>7</sub></small> and achieved improved high-valent redox behavior. Fe substitution leads to larger specific capacities (171 vs 159 mAh/g first cycle), enhanced cycle stability (97 vs 60 mAh/g after 50 cycles), and superior rate performance. This study lays the foundation for developing new cathode materials with stable high-valent redox through substitution of redox-active transition metals by employing cationic ordered vacancies and partial transition metal substitution as design principles in tandem.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"8 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143599040","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}

Therefore, it is imperative to minimize ΔEnr through rational molecular design and device engineering. In this work, three small molecular acceptors with different terminal steric hindrance groups (Y-PH-H, Y-PH-CH3, and Y-PH-2CH3) are designed as the third components to elaborately reduce the π-π interactions in the acceptor phase and improve the photoluminescence quantum yield (PLQY). All the third components effectively improve the fluorescence quantum yield of the acceptor phase and inhibit ΔEnr. Among these systems, the Y-PH-CH3 ternary system exhibits remarkable suppression of non-radiative energy loss, coupled with refined charge transport capabilities. Consequently, it achieves an impressive power conversion efficiency (PCE) of 18.63%, accompanied by a low non-radiative energy loss of merely 0.178 eV. Moreover, by adopting this third component design strategy into D18:L8-BO system, significantly improved open circuit voltage (VOC) of 0.924 V, and high PCE of 19.18% can be achieved.

Mendes","doi":"10.1039/d4ta08136f","DOIUrl":"https://doi.org/10.1039/d4ta08136f","url":null,"abstract":"A solar redox flow cell (SRFC) is singular in its ability to use a photoelectrochemical (PEC) cell for efficiently converting solar energy into electrochemical storable energy and heat. The generated solar fuels can be easily converted into electrical power at a redox flow battery (RFB). However, the SRFCs remain at a low Technology Readiness Level (TRL) mainly due to the low semiconductor efficiency, system durability, and lack of validated demonstrators. By leveraging the unique properties of tantalum nitride (Ta3N5) photoelectrodes, this work studies the role of this semiconductor material for the development of high performing SRFC devices. Opaque Ta3N5 photoelectrodes reached special interest for PEC water splitting due to the impressive photocurrent density achieved so far. However, for SRFC applications based on coloured electrolytes, Ta3N5 needs to be semi-transparent to allow backside sunlight illumination. Electrophoretic deposition (EPD) stands out as a suitable method for preparing semi-transparent Ta3N5 films. For the first time, the synthesis conditions were optimized, focusing on the EPD cycle time and annealing temperature, in an NH3 atmosphere, as well as employing a Ta‑doped TiO2 (TTO) underlayer for addressing simultaneously reproducibility and high efficiency. The best-performing bare Ta3N5 photoelectrodes were prepared with an electrophoretic deposition time of 7 min and annealed at 425 ºC, displaying an unprecedented photocurrent density of ca. 4.0 mA⸳cm-2 and a maximum power density of ca. 1.1 mW⸳cm-2, using a ferrocyanide-based electrolyte. These conditions allowed improving charge transfer kinetics and reducing recombination rates, as observed by electrochemical impedance spectroscopy. The optimized Ta3N5 photoelectrode was then paired with a perovskite solar cell, in a PEC-PV arrangement, to demonstrate 100 h operation of an aqueous alkaline SRFC, based on ferrocyanide (K4Fe(CN)6) and anthraquinone-2,7-disulphonate (2,7-AQDS) redox pairs both dissolved in KOH solutions.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"86 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143590142","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, electron transfer (ET) phenomena at the interface of graphitic electrodes and nonaqueous media are poorly understood, with several non-idealities in the use of conventional models such as the Butler–Volmer model reported. Possibilities for these non-idealities include the adsorption of redox species at the electrode, fundamental ET limitations related to the density of states at the electrode, and the presence of chemical and spatial heterogeneities at the surface of the electrode. To this point, we present a computational and experimental approach to comparatively investigate the ET behavior of two redoxmers, ferrocene (Fc) and 2,3-dimethyl-1,4-dialkoxybenzene (C7) on single layer graphene (SLG), hydrogen-functionalized SLG (H-SLG), and pristine and hydrogen-functionalized graphite electrodes. Scanning electrochemical microscopy (SECM) experiments revealed enhanced ET kinetics for both redoxmers on H-SLG electrodes compared to pristine SLG electrodes, with the degree of functionalization playing a key role in this enhancement. Electrodes such as boron-doped diamond and hydrogenated graphite mirrored these enhancements. Density functional theory (DFT) calculations indicate only small differences in the binding strengths for Fc and C7 redoxmers on SLG and H-SLG surfaces, but Marcus–Hush–Chidsey (MHC) kinetic theory analysis suggests that the density of states (DOS) of the carbon electrode likely plays a crucial role in the observed ET enhancement. These findings refine our initial assumption of binding energy (BE) as a dominant factor for interfacial behavior in the case of Fc and C7 redoxmers. Our findings create new opportunities to explore systems with varying degrees of surface modification to understand and design better redox flow batteries.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"41 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143599041","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}

Layered double hydroxides (LDH) based adsorbents are emerging as a promising potential for treating wastewater contaminated with difficult-to-remove organic dyes. However, single LDH adsorbents still face serious challenges in practical applications, including low adsorption capacity, poor structural stability, and a narrow pH range. Here, we employed a simple hydrothermal method to fabricate a 3D flower-like structure of FeOOH hybridized nickel-aluminum LDH (FeOOH@NiAl-LDH). The FeOOH derived from MOF-235 possesses a higher specific surface area and pore volume, which provides more adsorption sites and pore space, effectively enhancing the adsorption performance of Congo red (CR). Meanwhile, the interaction between FeOOH and NiAl-LDH enhances the structural stability of the adsorbent, endowing it with efficient adsorption and reproducibility under strongly alkaline conditions, thus achieving a dual enhancement in adsorption capacity (1297.0 mg/L) and stability under extreme pH (2−12) conditions. Additionally, the assessments for antibacterial activity and cytotoxicity confirms that FeOOH@NiAl-LDH exhibits excellent antibacterial activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Overall, this study not only provides new insights into the application of LDH in the field of water treatment but also offers important theoretical foundations for the design and preparation of high-performance dye adsorption materials.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"36 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143590153","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}

Unexpectedly, while a CaTiO3 cube presents (002) lattice fringes in transmission electron microscopy (TEM) images, a cuboid shows (001) lattice fringes. They also have discernably different lattice point patterns. These lattice features give rise to dissimilar dielectric constants and optical facet dependence. The cuboid crystals show stronger piezoelectric and ferroelectric responses than cubic particles do. Their surface properties differ completely with cuboidal particles being moderately active toward rhodamine B photodegradation, while cubes are inactive from floating above the dye solution with stirring. The CaTiO3 cuboids are more effective than cubes in photocatalyzing the formation of benzimidazole.

The electrochemical performance of existing ECDs, however, is often constrained by the conductivity of electrolytes, the contact interface between electrodes and electrolytes, and the severe intolerance of ECDs to low temperature environments. In this study, we couple two approaches. Firstly, we harness the Hofmeister effect to modulate the concentration of an ionic compound within the hydrogel electrolyte. This modulation enhances ion solvation and ionic conductivity, thereby facilitating internal ion transport within the self-powered ECD and accelerating the device's response time. Secondly, we illustrate how it is possible to capitalize on the designable properties of the substrate. Paper offers a unique controllable substrate structure, which can be readily modified in terms of surface micro-roughness, which, in turn, can be utilized during the forming of the gravure printed electrode. This novel optimization can improve the final surface morphology of the paper-based electrode, enhancing its surface area properties. This enhancement subsequently facilitates improved integration of the electrode interface with the hydrogel electrolyte, reducing interface impedance and increasing ion transport efficiency within the ECD. Combining this morphological effect with the increased ion solvation in the hydrogel electrolyte enables an improved electrochemical performance and cyclic stability, maintaining stability even at temperatures as low as −40 °C.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"60 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143589961","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}
