However, surface termination can hardly achieve effective and homogeneous passivation on large-area CsPbI3 films, which is one key challenge toward high-performance inorganic perovskite solar modules (PSMs). The strong ionic bond between Cs and the Pb-I framework in inorganic CsPbI3 makes it difficult to construct 2D perovskite layer on film surface via post treatment, which is otherwise a classic and effectual approach for defect elimination in organic–inorganic hybrid perovskites. Herein, a novel and programmable surface reconstruction strategy is reported that can facilely tune surface termination to 2D passivation on CsPbI3 perovskite using 2-(1-cyclohexenyl) ethyl ammonium iodide (CHEAI). In comparison to surface termination, the in situ formation of 2D CHEA2PbI4 by adjusting the stoichiometry of CHEAI demonstrates more comprehensive passivation effects and favorable energy level alignment for CsPbI3 films. Such 2D construction has greatly facilitated the enhancement on device performance, especially when scaling up the area. The optimal CsPbI3 PSM (active area of 12.44 cm2) based on 2D CHEA2PbI4 achieves a record-high efficiency of 19.32% (certified efficiency of 18.83%) with much improved stability, endorsing the practical promotion of this intrinsically stable perovskite material.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"218 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143723994","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}

Despite substantial progress, the practical application of e-textiles in wearable technologies remains limited by challenging tasks of integrating both optimal electrical performance and thermal-moisture comfort into a single fabric, particularly at industrial scales. Herein, leveraging a meta-textile structural design, a smart treble-weaving electronic textile (TWET) that combines highly sensitive sensing capabilities with radiative cooling is developed and enhanced sweat management through meta-yarn junction blocks forming hierarchical fabric architectures. Unlike conventional layered fabrics by simply compositing different functional layers, the TWET fabric integrates multimodal sensing, optical and moisture management into an all-in-one construction and leverages its interlacing structures as conduits for heat and moisture transmission, which contributes to outstanding thermal-moisture comfort. Moreover, it is demonstrated that the TWET performs robust monitoring and perception of human motion signals against heat stress. It is also shown that frequency-domain signals resulting from Fourier transformation can interpret and distinguish temporal-spatial features of regulating walking and stepping in place. This meta-textile hierarchical-assembly concept enables integrated thermal and moisture management in next-generation e-textiles, offering great potential for scalable production and multifunctionality through the precise engineering of meta-structures.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"48 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713567","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}

This study introduces a novel soft−hard interface design approach, which modifies the interlayer structure of Bi2Te3/MXene for the first time. Bi2Te3 is systematically assembled between MXene nanosheets via van der Waals forces, yielding a mechanically stratified architecture that combines both soft and hard components. In this configuration, MXene serves as a flexible buffer layer, mitigating the significant volume fluctuations of Bi2Te3 during Na-ion intercalation and de-intercalation, while concurrently establishing a conductive network that promotes rapid charge transfer. In-situ TEM analysis demonstrates a rapid and reversible intercalation/de-intercalation process between the Bi2Te3 and MXene layers, which is pivotal for enhancing rate capability and cycling stability of the material. Theoretical calculations and COMSOL simulations further elucidate that MXene markedly improves charge transfer in Bi2Te3 and mitigates its volume expansion. As a result, the Bi2Te3/MXene composite exhibits exceptional electrochemical performance.

However, the synthesis of APSNCs with well-defined active centers and stable structures remains a huge challenge due to uncontrollable aggregation during synthesis and catalytic reactions. Herein, the Ru3 nanocluster catalysts uniformly dispersed on oxidized carbon nanotubes (Ru3/OCNT) is successfully synthesized by using a rapid pyrolysis of precursor strategy. The obtained Ru3/OCNT exhibits excellent catalytic performance for alkaline hydrogen evolution reaction (HER). The catalyst achieves an overpotential of 19 mV at a current density of 10 mA cm−2 in 1 m KOH solution, outperforming commercial 20 wt.% Pt/C and 5 wt.% Ru/C. Moreover, the mass activity of Ru3/OCNT is 23.47 and 11.83 times higher than that of commercial Pt/C and Ru/C. Density functional theory (DFT) calculations reveal that the metal–metal interaction and metal–support interaction in Ru3/OCNT effectively modulate the electronic structure of Ru atoms, lower the hydrogen adsorption energy of the catalytic site, and promote the H* desorption.

Herein, a dual structural engineering strategies of electron configuration modulation and molecular intercalation for the regulation of desolvation kinetics between nitrogen-doped lamellar carbon-intercalated 1T-molybdenum disulfide (MoS2) superlattice nanoflower (1T-MoS2-NC) and Na(H2O)x+ is demonstrated. The synergy of cation-π interaction and adjustable interlayer structure induced by NC intercalation reduces the desolvation energy and promotes dehydration degree of Na(H2O)x+, thereby providing more interspace for Na+ accommodation. The abundant 1T metal phase accelerates the charge transfer while lowering the Na+ diffusion energy barrier. Benefitting from the advantages above, 1T-MoS2-NC exhibits superior capacitive deionization performance, including outstanding brackish water desalination capacity (80.9 mgNaCl g−1) and splendid long-term stability in a 1000 mg L−1 NaCl solution at a cell voltage of 1.4 V, which exceeds most of the state-of-the-art electrodes under similar experimental conditions.

Hydrovoltaic devices have garnered widespread attention due to their miniaturization, portability, and substantial power generation potential. However, solid-liquid interactions in conventional hydrovoltaic devices are limited by the strong screening charge effect of the film structures, which leads to diminished device performance. This work presents a three-dimensional (3D) synergistic strategy for patterning zinc oxide (ZnO) hydrovoltaic devices to achieve high voltage output. At 50% relative humidity and 20 °C, the single patterned ZnO hydrovoltaic device can continuously generate a pulse voltage exceeding 9 V within 7 h, which is 15 times greater than the 0.6 V of similarly sized ZnO thin-film device. Further assembling multiple parallel units of patterned ZnO, a power supply is conducted well for a watch demonstration. Moreover, the lightweight (20 g m−2) and flexible characteristics of the patterned ZnO hydrovoltaic devices make them ideal for large-area integration and energy collection in practical applications. Thousands of printed and fabricated patterned ZnO devices will be expected to establish surface micro/nanostructure platforms for various energy devices in outdoor environments through extensive series-parallel connections.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"18 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713624","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}

Combining experimental characterizations and theoretical calculations, this confirms that solvated water and free water are the key variables dominating the onset potential and intensity of HER, respectively. An in-depth understanding of the HER process realizes better HER inhibition through synchronously weakening onset potential and HER activity. Additionally, fixed multi-polyanions and salt anions endow PAHE with high cation transfer efficiency and accelerated desolvation kinetics by forming cooperative ion pairs. Consequently, structurally and electrochemically stable PAHE optimizes the Zn-electrolyte interface, markedly enhancing Zn chemistry reversibility.

Herein, a local phosphorization strategy by precisely controlling phosphorus (P) atom doping location is presented to modulate the IEF orientation smartly in high-low crystalline carbon nitride (g-C3N4) homojunction. Different orientation of IEF is found to guide different photocatalytic reaction paths. By incorporating P in low-crystalline g-C3N4 (P-LCN), IEF is modulated by directing from P-LCN to high-crystalline g-C3N4 (HCN), which contributes to S-scheme mechanism over the P-LCN/HCN homojunction. Conversely, P doping in HCN (P-HCN) modulates the IEF in LCN/P-HCN reversing from P-HCN to low-crystalline g-C3N4 (LCN), and the photocatalytic reaction follows type-II mechanism. Profiting from the effective photocarriers transfer and separation dynamics, especially the favored electrons reducing capacity, P-LCN/HCN performs a superior H2 evolution (12.09 mmol·g−1·h−1) than LCN/P-HCN (4.53 mmol·g−1·h−1).
