Hierarchical Porous Fe<inf>3</inf>C@Fe-N-C Catalysts from Tannin-Fe(III) Complexes for Efficient Oxygen Reduction

AbstractThe rational design of metal‐nitrogen‐doped carbons (M‐N‐C) from available and cost‐effective sources featuring high electrocatalytic performance and stability is attractive for the development of viable low‐temperature fuel cells. Herein, mimosa tannin, an abundant polyphenol easily extracted from the Mimosa plant, is used as a natural carbon source to produce a tannin‐Fe(III) coordination complex. This process is assisted by Pluronic F127, which acts as both a surfactant and a promoter of Fe‐Nx active sites. After carbonization in the presence of urea as a nitrogen precursor, this organic tannin‐Fe(III) framework produces Fe3C nanoparticles encapsulated on a Fe‐N‐C single‐atom catalyst with hierarchical porosity. The optimal catalyst, with a Pluronic F127/mimosa tannin mass ratio of 0.5, exhibits high ORR performance in both alkaline and acidic electrolytes, with half‐wave potentials of 0.87 and 0.74 V versus RHE, respectively. In addition, good performance is achieved in practical hydrogen polymer‐electrolyte membrane fuel cells using OH−‐ or H+‐conducting membranes with peak power densities of 242 and 200 mW cm−2 at cell voltages of 0.43 and 0.3 V, respectively. The synthetic approach can be explored to design new renewable M‐N‐C electrodes for electrochemical energy conversion or storage devices due to tannin's exceptional ability to coordinate metals.

The increasing demand for lithium‐ion batteries (LIBs), primarily driven by the expanding electric vehicle market and the growing need for efficient energy storage, presents both significant opportunities and challenges. The efficient and cost‐effective regeneration of spent LIBs is crucial to minimizing environmental impact and fostering a true circular economy for battery materials. Herein, an innovative one‐step lithiation process is introduced for spent LiFePO4 cathodes, conducted in aqueous solution under ambient conditions. This method utilizes readily available and low‐cost reagents, including a lithium source and ascorbic acid (vitamin C) as a green reducing agent, offering a substantial advantage over traditional techniques that require harsh conditions and complex setups. The lithiation reaction proceeds rapidly, producing pure and fully regenerated LFP. This environmentally friendly process was successfully demonstrated at the scale of 18650 cells with electrodes composed entirely of recycled LFP. These cells exhibit excellent electrochemical performance, even after 1000 cycles at 1C rate, comparable to those made with pristine LFP. By providing a sustainable, cost‐effective, and easily scalable solution for LFP cathode regeneration, the approach supports the closure of the materials loop, contributing to the sustainable management of LIBs and advancing the shift toward a circular economy.


Olivine NaMn<inf>0.66</inf>Fe<inf>0.34</inf>PO<inf>4</inf> as a Cathode Material for Advanced Sodium Ion Batteries
Tassadit Ouaneche, Lorenzo Stievano, Laure Monconduit, Claude Guéry, Moulay Tahar Sougrati, and Nadir Recham
Wiley
AbstractSodium‐ion batteries continue to rise in the energy storage landscape, their increasing adoption being driven by factors such as cost‐effectiveness and sustainability. As a consequence, there is a growing emphasis on the development of new electrode materials. Among these, olivine phosphates emerge as a promising family of cathode materials. However, viable synthesis routes are still lacking. In this study, cathode materials of olivine NaMn1‐xFexPO4 (x=0.34 and 1) were prepared by directly sodiating Mn1‐xFexPO4 through a solid‐state process at 300 °C. X‐ray diffraction, Mössbauer spectroscopy and electrochemical measurements were employed to study their structural and electrochemical features. NaMn0.66Fe0.34PO4 exhibits two pseudo‐plateaus profile with an average potential of ~3.2 V vs. Na+/Na0 with a reversible capacity reaching 75 mAh/g at C/20 via a monophasic (de)intercalation mechanism. In parallel, the intermediate composition Na0.5Mn0.66Fe0.34PO4 could be prepared via the solid‐state reaction of NaMn0.66Fe0.34PO4 and Mn0.66Fe0.34PO4. Such a solvent‐free sodiation process not only provides a simplified preparation of NMFP, but also offers easy scalability compared to the more laborious electrochemical sodiation route, making it an interesting prospect for future industrialization. Finally, this research confirms that the olivine NMFP is indeed an attractive candidate as a cathode material for SIBs.

Prussian blue analogues receive tremendous attention owing to their spacious three-dimensional skeleton, high theoretical specific capacity, facile synthesis procedure, and high cost-effectiveness as among the most promising candidates for cathode materials in sodium-ion batteries (SIBs). Nonetheless, the practical specific capacity, especially under high current, is particularly frail due to the sluggish ion diffusion. In this study, the strategy of Ni substitution and formation of water-coordinated Fe is applied to lower the crystal field energy and elevate the active low-spin (LS) Fe content, which leads to a capacitive sodium storage mechanism, resulting in a substantial specific capacity under high current density. The delivered specific capacity of PW-325@2NiFe-55 is 95 mAh g-1 at 50 C, which is 72.5% capacity retention of the one at 0.5 C. Also, it maintains 80.2% of its initial specific capacity after 500 cycles at 5 C. Furthermore, a hypothesis of a joint diffusion-controlled and capacitive mechanism for high-spin (HS) Fe and a mere capacitive mechanism for LS Fe is put forward and verified through potentiastatic tests, operando 57Fe Mössbauer spectroscopy, and ex situ XRD, which provides a new horizon to enhance the electrochemical performance for SIBs.

Mononuclear Fe ions ligated by nitrogen (FeNx) dispersed on nitrogen-doped carbon (Fe-N-C) serve as active centers for electrocatalytic O2 reduction and thermocatalytic aerobic oxidations. Despite their promise as replacements for precious metals in a variety of practical applications, such as fuel cells, the discovery of new Fe-N-C catalysts has relied primarily on empirical approaches. In this context, the development of quantitative structure-reactivity relationships and benchmarking of catalysts prepared by different synthetic routes and by different laboratories would be facilitated by the broader adoption of methods to quantify atomically dispersed FeNx active centers. In this study, we develop a kinetic probe reaction method that uses the aerobic oxidation of a model hydroquinone substrate to quantify the density of FeNx centers in Fe-N-C catalysts. The kinetic method is compared with low-temperature Mössbauer spectroscopy, CO pulse chemisorption, and electrochemical reductive stripping of NO derived from NO2- on a suite of Fe-N-C catalysts prepared by diverse routes and featuring either the exclusive presence of Fe as FeNx sites or the coexistence of aggregated Fe species in addition to FeNx. The FeNx site densities derived from the kinetic method correlate well with those obtained from CO pulse chemisorption and Mössbauer spectroscopy. The broad survey of Fe-N-C materials also reveals the presence of outliers and challenges associated with each site quantification approach. The kinetic method developed here does not require pretreatments that may alter active-site distributions or specialized equipment beyond reaction vessels and standard analytical instrumentation.

Wiley
AbstractThe iron‐based polyanionic fluoro‐oxalate material, KFe(C2O4)F (KFCF), has been synthesized by hydrothermal methods. This compound shows promising reversible lithium and sodium insertion properties as a cathode material. The material delivered a first‐cycle discharge capacity of 120 mAh g−1 at ∼3.3 V (Li+/Li) and 97.4 mAh g−1 at ∼3.0 V (Na+/Na) in LIB and NIB, respectively. Stable cycling performance was observed in both cases. The involvement of reversible Fe2+/Fe3+ redox was confirmed by ex‐situ Mössbauer spectroscopy supported by first‐principles calculations. This study reveals promising performance from a mixed oxalate‐fluoride based polyanionic material thereby opening up further possibilities for materials discovery in the design of new electrode materials.

While improved activity was recently reported for bimetallic iron-metal-nitrogen-carbon (FeMNC) catalysts for the oxygen reduction reaction (ORR) in acid medium, the nature of active sites and interactions between the two metals are poorly understood. Here, FeSnNC and FeCoNC catalysts were structurally and catalytically compared to their parent FeNC and SnNC catalysts. While CO cryo-chemisorption revealed a twice lower site density of M-Nx sites for FeSnNC and FeCoNC relative to FeNC and SnNC, the mass activity of both bimetallic catalysts is 50-100% higher than that of FeNC due to a larger turnover frequency in the bimetallic catalysts. Electron microscopy and X-ray absorption spectroscopy identified the coexistence of Fe-Nx and Sn-Nx or Co-Nx sites, while no evidence was found for binuclear Fe-M-Nx sites. 57Fe Mössbauer spectroscopy revealed that the bimetallic catalysts feature a higher D1/D2 ratio of the spectral signatures assigned to two distinct Fe-Nx sites, relative to the FeNC parent catalyst. Thus, the addition of the secondary metal favored the formation of D1 sites, associated with the higher turnover frequency.
