However, synthesizing metastable noble metals like Ru remains challenging due to strong metallic bonding. Herein, a solvent dynamics‐limiting effect is proposed to regulate the dynamics of nucleation and growth processes to achieve the precise synthesis of metastable metal fcc‐Ru. Furthermore, on the basis of the solvent dynamics‐limiting effect, the construction of metastable/stable homoatomic fcc/hcp‐Ru heterophase interface is successfully realized through a dynamic slow phase transformation strategy. The experimental result shows that the generation of homoatomic heterophase interfaces combines the superiority of different crystal phases and enhances intrinsic activity and stability, thus promoting efficient HER performance in a wide pH range. Specifically, overpotentials as low as 17.1/22.9/22.6 mV are required to achieve 10 mA cm−2 current density in alkaline/neutral/acidic conditions with significantly improving stability. Theoretical calculations demonstrate that the construction of homoatomic heterophase interfaces reduces the dissociation energy of water, optimizes the catalyst's adsorption capacity for hydrogen, thereby promoting an efficient HER pathway. Moreover, the proposed method has potential applications for other metals and oxides, offering new insights for crystal phase engineering.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"72 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144622262","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}

In this proof‐of‐concept study, a systematic methodology is introduced for the preparation of multilayer catalysts that combines Radio Frequency (RF) magnetron sputtering with laser microstructuring for the synthesis of high‐density Cu/ZnO interfaces. By means of a specifically designed split target, alternating few‐nanometer‐thick layers of Cu and ZnO are deposited under precise control and with high reproducibility. Laser scribing is then employed to create defined microstructures that reveal buried interfaces, improving access to catalytically active interfaces. As‐deposited and laser‐scribed multilayer's structural and chemical stability is confirmed through Atomic Force Microscopy (AFM), X‐Ray Fluorescence (XRF), X‐Ray Diffraction (XRD), X‐Ray Photoelectron Spectroscopy (XPS), and Scanning Electron Microscope (SEM) characterizations. Catalytic activity is evaluated under gradient‐free, continuous‐stirring conditions for CO2 hydrogenation to methanol where the catalyst produces methanol and CO under laboratory‐scale conditions. The strategy addresses specific design bottlenecks such as limited control over interfacial geometry and exposure while acknowledging the inherent limitations of thin‐film systems in terms of surface area and scalability. While demonstrated for CO2‐to‐methanol conversion, the method is generally applicable to other interface‐dependent reactions.

However, the uncontrolled proliferation of zinc dendrites and severe interfacial side reactions have emerged as substantial obstacles to their practical application. In this study, a novel “polar ionic hub regulation” strategy is introduced, which involves the covalent bonding of hydrophilic‐hydrophobic bifunctional groups to construct an asymmetric topological structure, thereby forming a nanoscale Janus interface at the molecular level. The carboxyl and amide groups synergistically anchor Zn2+ ions through spatial cooperation, creating localized Zn2+‐rich domains. Meanwhile, the benzene ring repels free water molecules via its hydrophobic effect, effectively blocking the interfacial side reactions initiated by water molecules. Consequently, the zinc anode achieves an ultralong cycling lifespan exceeding 3600 h at 1 mA cm−2 and 1 mAh cm−2. Moreover, the zinc symmetric cell attains a cumulative plating capacity of 4.875 Ah cm−2 at a high areal capacity of 5 mAh cm−2.

Kinetic calculations present that the flow system optimizes the first‐order reaction of the conventional non‐flow system to zero‐order reaction, which facilitates the efficient and long‐lasting photocatalytic CO2RR. Ab initio quantum chemical simulations of both the ground and excited states reveal that the enhanced performance stems from charge transfer photoexcitation associated with the doped single Co atom, which facilitates proton adsorption, reduces the energy barrier, and promotes C–OH bond cleavage. Taking advantage of the three‐phase flow system and single‐atom catalyst, the CO generation rate increases to 2.35 µmol h−1 with a selectivity of 97.8%.

However, perovskite solar cells still face problems such as poor stability and lead toxicity, and it is both time‐consuming and expensive to find new materials with properties that meet the demand through traditional trial‐and‐error methods. To address this problem, a multi‐property screening method is proposed for lead‐free halide double perovskite based on a transfer learning technique. First, a source domain model with the formation energy of halide double perovskites as the target property is established, and high‐precision predictive models of Ehull, band gap, bulk modulus, and shear modulus are constructed by the transfer learning technique. In particular, the “continuous transfer” method is proposed. The bulk modulus model, after transfer learning, is used as the source domain model to transfer the shear modulus model again. Finally, the high‐throughput screening of multi‐properties of halide double perovskites are successfully realized, and computationally verified that the Cs2CuIrF6 material has good stability, a suitable bandgap (1.06 eV), and ductility (G/B = 0.27). This proposed transfer learning strategy provides an effective method for screening stable perovskite materials with potential for multiple optoelectronic applications.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"14 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144622266","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}
