Herein, we use the alkaline characteristics of RLCs to convert harmful RLCs into functional molecular layer during slurry preparation process, facilitating the formation of a stable cathode electrolyte interfacial (CEI) layer. As a proof of concept, 2,5-thiophenediylbisboronic acid (TDBA) is selected for surface molecular engineering of single-crystal LiNi0.92Co0.05Mn0.03O2 cathode through neutralization with RLCs. After in situ electrochemical reaction, the uniform and stable CEI forms and provides high Li+ diffusivity and mechanical strength, effectively suppressing cathode particle cracking and electrolyte decomposition.

They govern multiple critical factors affecting the operation of photovoltaic devices such as the energetics of the contact, and the crystallization process of the thin film, thus its structural and electronic quality. Self-assembled monolayers (SAMs) have emerged as promising candidates as hole-selective materials for inverted PSCs, thanks to the flexibility provided by the large library of their functional groups. Herein, we outline a molecular hybridization strategy through the incorporation of the histamine molecule into the [4-(3,6-dimethyl-9H-carbazol-9yl)butyl]phosphonic acid (Me-4PACz), which is one of the most common hole extracting layers. Playing with intermolecular strong and weak interactions, we can contextually act on multiple processes. The proton transfer from the phosphonic acid group of the Me-4PACz to the ethylamine functional group of histamine enables the design of the interface dipole to facilitate hole extraction and minimize recombination losses. Then, the protonated amines balance the nucleation of halide components and stabilize the halide ions in the perovskite, avoiding their migration. Thus, three-dimensional nanovoids and tensile stress at the bottom surface were reduced, stabilizing the buried interface. Finally, the π-π interactions between the imidazole moiety and Me-4PACz improve the molecular assembling of the SAM, reducing disorder at the interfacial contact. The general impact of these results has been tested on PSCs based on lead mix-halide perovskites with two different bandgaps. The inverted WBG PSCs with 1.77 eV bandgap present a power conversion efficiency (PCE) of 20.34%, and maintains 95.5% of the initial PCE after 1000 hours of continuous illumination. The highly challenging WBG PSCs with 1.83 eV bandgap deliver a PCE of 18.99% with a Voc as high as 1.364 V-ranking among the highest reported PCEs and Voc values for such large bandgap.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"18 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910191","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}

Current catalysts also suffer from ultra-low loadings (< 1.0 wt.%) of atomic metal active sites in catalysts, leading to inadequate performance for CO2-to-CO conversion. Here, we develop dual Ni/Fe metal site catalysts with significantly increased atomically dispersed metal loadings (up to 4.8 wt.%). We developed a gas-phase chemical vapor deposition (CVD) approach to introduce single Ni sites into Fe2O3/ZIF-8 precursors, followed by an optimal thermal activation. The optimized CVD-Ni/Fe-N-C catalyst exhibited remarkable electrocatalytic performance for the CO2 reduction to CO in a continuous membrane-electrode-assembly electrolyzer, achieving a maximum CO Faradaic efficiency (FECO) of 96% at a current density of 700 mA cm−2 in a near-neutral electrolyte. Furthermore, a desirable but challenging acidic flow-cell electrolyzer was designed using this dual metal site catalyst to improve CO2 utilization, accomplishing a FECO of up to 95% at a CO partial current density close to 600 mA cm−2. Density functional theory (DFT) calculations suggest a synergetic effect between Fe-Ni pairs facilitating *COOH intermediate formation and *CO desorption simultaneously during CO2 to CO conversion.
