This work explores a new family of MnOx-supported IrOx and IrRuOx electrocatalysts for the acidic oxygen evolution reaction (OER). Comprehensive ex situ and in situ characterization uncovers synthesis-structure-activity relationships of the OER materials with insight into the origin of their exceptional activity: The MnOx support provides beneficial dispersion while the introduction of Ru into IrOx/MnOx leads to a modulation of the chemical state of Ir coupled with a strong surface reconstruction. In half-cell tests, IrRuOx/MnOx reveals an Ir mass activity of 964.7 A gIr−1 at 1.53 VRHE, which is 36 times higher than that of the commercial IrO2 (C-IrO2). It is also demonstrated that this promising catalytic OER activity translates into a realistic PEMWE performance. IrRuOx/MnOx and IrOx/MnOx thin catalyst layers are developed in low Ir-loaded membrane electrode assemblies (MEAs) and an outstanding PEMWE cell performance is reported with cell voltages of 1.66 V at 2 A cm−2. This translates into a favorable (Ir + Ru) platium group metal (PGM) demand of <0.05 gPGM kW−1 at 70% voltage efficiency, meeting a 2035 technical demand target.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"43 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their performance on rough substrates and large-area devices is often hampered by SAMs self-clustering and poor perovskite wettability. In this study, these limitations are addressed with a straightforward micelle-assisted SAMs adsorption strategy. By incorporating a small amount of long-chain surfactants into the SAMs solution, the surfactants aggregate to form micelles that encapsulate SAMs molecules within their hydrophobic cores, significantly increasing the adsorption density of SAMs through micelle-admicelle interactions. Notably, the residual surfactants further improve perovskite wettability, enhance crystal quality, and facilitate hole transport across the buried interface. Consequently, the wide-bandgap single-junction perovskite solar cell achieves a notable power conversion efficiency (PCE) of 20.95% and enhances long-term stability compared to control devices. By integrating tunnel oxide passivated contact (TOPCon) silicon solar cells, a 1 cm2 monolithic perovskite/silicon tandem device achieving a PCE of 29.8% is demonstrated, ranking among the highest reported efficiencies for perovskite/homojunction silicon tandem solar cells. Furthermore, the unencapsulated device maintains 92% of its initial performance after 300 h of maximum power point (MPP) tracking under unfiltered Xenon Lamp illumination.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"69 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143641140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the disparity in synthesis methods, catalyst formulations, and structures previously studied precludes quantitative comparisons between the two families. Herein, a rigorous framework is pioneered to benchmark InZrOx and ZnZrOx materials prepared by a standardized flame spray pyrolysis synthesis platform, enabling consistently high surface areas and tunable metal speciation ranging from isolated atoms (<5 mol%) to predominantly nanoparticles (>10 mol%). Isolated indium and zinc species are commonly identified to be optimal for activity and methanol selectivity in their respective families, maximizing CO2 and H2 activation abilities. InZrOx outperforms ZnZrOx across speciations and is less structure sensitive, as deviations from atomic dispersion is less detrimental on performance for the former. Focusing on representative catalysts featuring saturation of isolated species, the higher activity of 5 mol% InZrOx over its ZnZrOx counterpart is linked to differences in surface oxygen vacancy chemistry, a lower degree of product inhibition, and more facile hydrogenation of the formate intermediate to methoxy. The identification of reactivity descriptors governing both families facilitates the development of unified guidelines in designing reducible oxide catalysts.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"6 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143641145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, SSCs tend to exhibit a 2-electron transfer reaction in CO2RR, and there remain significant challenges in achieving efficient conversion above 2-electrons (methane (CH4) and multicarbon products(C2+). Therefore, a systematic review is crucial to summarize the recent advancements in single site CO2 electrocatalysts and their structure-activity relationship. The discussion begins with the state-of-the-art characterization techniques of SSCs. Then the influence of central atoms, coordination environments, support and metal-support interactions on catalytic performance of SSCs is discussed in detail. Subsequently, the regulation strategies to improve the activity and selectivity of CH4 and C2+ products are discussed. Furthermore, the dynamic evolution of metal active sites and the true nature of active sites during CO2RR are also addressed.

Conventional approaches to mitigate crystallinity necessitate elevated operation temperatures of 50–60 °C. Interestingly, this work indicates that the predominant factor limiting ambient-temperature performance is the robust coordination between lithium-ion (Li+) and ether oxygen (EO), rather than the crystallinity. By rationally tailoring the Li+ concentration, this work effectively weakens the coordination strength, thereby enhancing the ambient-temperature electrochemical performance. An optimal SPE with EO: Li ratio of 9:1 exhibits remarkable ionic conductivity (1.76 × 10−4 S cm−1 at 35 °C), a high Li+ transference number (0.486 at 35 °C), and superior adhesion to electrodes in compression-free pouch cells. The practical feasibility of the SPE is demonstrated in solid-state Li-LiFePO4 cells achieving a specific capacity of 149.66 mAh g−1 at 0.1 C and 35 °C and 90.5% capacity retention over 100 cycles. The electrolyte also exhibits compatibility with high-voltage cathodes of LiNi0.6Co0.2Mn0.2O2 and LiNi0.8Co0.1Mn0.1O2 for high-energy Li-metal batteries.

Here in this work, this challenge is addressed by developing a photothermal system that synthesizes ammonia from nitrogen and natural seawater under simulated solar irradiation, employing ruthenium-doped barium tantalum oxynitride semiconductors. This method significantly enhances solar-to-ammonia conversion efficiency, providing a viable alternative to the energy-intensive Haber–Bosch process. Optimized at 240 °C, the system achieves an ammonia evolution rate of 5869 µmol g−1 h−1 in natural seawater. Moreover, detailed characterizations have shown that the use of seawater not only leverages an abundant natural resource but also improves the reaction kinetics and overall system stability. The catalysts maintain their activity and structural integrity over multiple cycles, demonstrating both the feasibility and the durability of this innovative system. Achieving a solar-to-ammonia efficiency of 13% and an overall energy conversion efficiency of 6.3%, this breakthrough highlights the potential to decentralize ammonia production, enhancing accessibility and sustainability.

However, the limited energy density remains a major obstacle to further advancement of NVP. Herein, a medium-entropy NASICON Na3.3V1.4Al0.3(MgCoNiCuZn)0.06(PO4)3 (NVAMP-0.3) is designed by introducing Al3+, Mg2+, Co2+, Ni2+, Cu2+, and Zn2+ to regulate configurational entropy. These NVAMP-0.3 achieve an elevated average operating voltage (3.33 V) and high capacity (138.1 mAh g−1, based on 2.3 Na+) through V3+/V4+/V5+ multi-electron reactions. By simultaneously enhancing capacity and voltage, NVAMP-0.3 exhibits an impressive energy density of 460 Wh kg−1. Furthermore, NVAMP-0.3 demonstrates excellent low-temperature tolerance with a capacity retention rate of 94.6% after 300 cycles at −40 °C. In situ XRD unveils the underlying cause of the unique phenomenon where the solid-solution reaction accounts for the faster electrochemical reaction kinetics of the V4+/V5+ compared to the V3+/V4+ redox. DFT calculations indicate that NVAMP-0.3 possesses superior electronic conductivity and reduced Na+ migration energy barriers.
