Metal oxide-supported multielement alloy nanoparticles are very promising as highly efficient and cost-effective catalysts with a virtually unlimited compositional space. However, controllable synthesis of ultrasmall multielement alloy nanoparticles (us-MEA-NPs) supported on porous metal oxides with a homogeneous elemental distribution and good catalytic stability during long-term operation is extremely challenging due to their oxidation and strong immiscibility. As a proof of concept that such synthesis can be realized, this work presents a general “bottom-up” l ultrasonic-assisted, simultaneous electro-oxidation–reduction-precipitation strategy for alloying dissimilar elements into single NPs on a porous support. One characteristic of this technique is uniform mixing, which results from simultaneous rapid thermal decomposition and reduction and leads to multielement liquid droplet solidification without aggregation. This process was achieved through a synergistic combination of enhanced electrochemical and plasma-chemical phenomena at the metal–electrolyte interface (electron energy of 0.3–1.38 eV at a peak temperature of 3000 K reached within seconds at a rate of ~105 K per second) in an aqueous solution under an ultrasonic field (40 kHz). Illustrating the effectiveness of this approach, the CuAgNiFeCoRuMn@MgO-P3000 catalyst exhibited exceptional catalytic efficiency in selective hydrogenation of nitro compounds, with over 99% chemoselectivity and nearly 100% conversion within 60 s and no decrease in catalytic activity even after 40 cycles (>98% conversion in 120 s). Our results provide an effective, transferable method for rationally designing supported MEA-NP catalysts at the atomic level and pave the way for a wide variety of catalytic reactions.

Breakthroughs brought about by two-dimensional (2D) materials in the field of photodetection have opened up new possibilities in infrared imaging. However, challenges still exist in fabricating high-density detector arrays using such materials, which are essential for traditional imaging systems. In this study, we present a state-of-the-art computing imaging system that utilizes a MoTe2/Si self-powered photodetector coupled with flexible Hadamard modulation algorithms. This system demonstrates remarkable capability to produce high-quality images in the shortwave infrared (SWIR) band, surpassing the capabilities of devices based on alternative material systems. The exceptional infrared imaging capability primarily stems from the MoTe2/Si photodetector's inherent features, including an ultra-wide spectral range (265–1550 nm) and extremely high sensitivity (linear dynamic range (LDR) up to 123 dB, responsivity (R) up to 0.33 A W–1, external quantum efficiency (EQE) up to 43% and a specific detectivity (D*) exceeding 2.9 × 1011 Jones). Moreover, the imaging system demonstrates the ability to achieve high-quality edge imaging of objects in the SWIR band (1550 nm), even in strong scattering environments and under low sampling rate conditions (sampling rate of 25%). We believe that this work will effectively advance the application scope of 2D materials in the field of computational imaging in SWIR bands.

Static rechargeable zinc-iodine (Zn-I2) batteries are superior in safety, cost-effectiveness, and sustainability, giving them great potential for large-scale energy storage applications. However, the shuttle effect of polyiodides on the cathode and the unstable anode/electrolyte interface hinder the development of Zn-I2 batteries. Herein, a self-segregated biphasic electrolyte (SSBE) was proposed to synergistically address those issues. The strong interaction between polyiodides and the organic phase was demonstrated to limit the shuttle effect of polyiodides. Meanwhile, the hybridization of polar organic solvent in the inorganic phase modulated the bonding structure, as well as the effective weakening of water activity, optimizing the interface during zinc electroplating. As a result, the Zn-I2 coin cells performed a capacity retention of nearly 100% after 4000 cycles at 2 mA cm−2. And a discharge capacity of 0.6 Ah with no degradation after 180 cycles was achieved in the pouch cell. A photovoltaic energy storage battery was further achieved and displayed a cumulative capacity of 5.85 Ah. The successfully designed energy storage device exhibits the application potential of Zn-I2 batteries for stationary energy storage.

Lithium metal batteries (LMBs) are desirable candidates owing to their high-energy advantage for next-generation batteries. However, the practical application of LMBs continues to be constrained by thorny safety issues with the formation and growth of Li dendrites. Herein, the ZIF-67 MOFs are in situ coupled onto a single face of 3D porous nanofiber to fabricate an asymmetric Janus membrane, harnessing their anion adsorption capabilities to promote the uniform deposition of Li ions. In addition, the poly(ethylene glycol) diacrylate and trifluoromethyl methacrylate are introduced into nanofiber skeleton to form Janus@GPE, which preferentially reacts with Li metal to form a LiF-rich stable SEI layer to inhibit Li dendrite growth. Importantly, the synergistic effect of the MOFs and stable solid electrolyte interphase (SEI) layer results in superior cycling performance, achieving a remarkable 2500 h cycling at 1 mA cm−2 in the Li/Janus@GPE/Li configuration. In addition, the Janus@GPE electrolyte has a certain flame retardant, which can self-extinguish within 3 s, improving the safety performance of the batteries. Consequently, the Li/Janus@GPE/LFP flexible pouch cell exhibits favorable cycling stability (the capacity retention rate of 45 cycles is 91.8% at 0.1 C). This work provides new insights and strategies to improve the safety and practical utility of LMBs.
锂金属电池（LMB）具有高能量优势，是下一代电池的理想候选材料。然而，LMB 的实际应用仍然受到锂枝晶形成和生长的棘手安全问题的制约。在本文中，ZIF-67 MOFs 被原位耦合到三维多孔纳米纤维的单面上，制成了非对称 Janus 膜，利用其阴离子吸附能力促进锂离子的均匀沉积。此外，在纳米纤维骨架中引入聚乙二醇二丙烯酸酯和甲基丙烯酸三氟甲基酯，形成 Janus@GPE，优先与金属锂反应，形成富含 LiF 的稳定 SEI 层，抑制锂枝晶的生长。重要的是，MOFs 和稳定的固体电解质相（SEI）层的协同效应带来了卓越的循环性能，在锂/Janus@GPE/锂配置中，1 mA cm-2 的循环时间达到了 2500 h。此外，Janus@GPE 电解质具有一定的阻燃性，可在 3 秒内自熄，提高了电池的安全性能。因此，锂/Janus@GPE/LFP 柔性袋电池表现出良好的循环稳定性（在 0.1 C 下，45 次循环的容量保持率为 91.8%）。这项工作为提高锂电池的安全性和实用性提供了新的见解和策略。

Broadband photodetectors (PDs) capable of multi-wavelength detection have garnered significant interest for applications in environmental monitoring, optical communication, spectral analysis, and imaging sensing. Low-bandgap Pb–Sn hybrid perovskite photodetectors can extend the spectral response from the ultraviolet–visible (UV–vis) range to the near-infrared (NIR) and reduce the toxicity associated with Pb2+. The strategic introduction of Sn2+ into Cs0.15FA0.85PbxSn1−xI3 (x = 1, 0.8, 0.6, 0.5, 0.4, 0.2, and 0) not only preserves the cubic crystal structure with conformal multigrain growth but also broadens the film's absorption spectrum from 800 to 1000 nm NIR region. This indicates a well-controlled tunability of the Pb–Sn binary perovskite system. Specifically, the self-powered photodetector with a device structure of ITO/NiOx/PTAA/Cs0.15FA0.85Pb0.5Sn0.5I3/PCBM/BCP/Ag has shown remarkable optoelectrical properties. It exhibits a high external quantum efficiency (EQE) of up to 80% across the spectrum from 300 to 1000 nm, a responsivity (R) exceeding 0.5 A/W, and high detectivity (D*) value of 1.04 × 1012Jones at 910 nm and 3.38 × 1011Jones at 1000 nm after weak attenuation. Intriguingly, the dark current of the Cs0.15FA0.85Pb0.5Sn0.5I3 device is four orders of magnitude lower than that of devices made with pristine Pb or Sn only, strongly correlating with its significantly increased built-in potential and reduced trap density. Consequently, it demonstrates a −3 dB bandwidth of 2.23 × 104 Hz, fast rise and decay times of 61 and 30 μs, respectively, and a linear dynamic range (LDR) of 155 dB. Benefiting from its high sensitivity, a 5 × 5 PD array for NIR imaging and non-invasive pulse detection for photoplethysmography applications has been successfully demonstrated, showcasing the prosperous potential of Pb–Sn hybrid perovskite in the NIR range.

Aqueous zinc‐ion batteries (AZIBs) have garnered significant research interest as promising next‐generation energy storage technologies owing to their affordability and high level of safety. However, their restricted ionic conductivity at subzero temperatures, along with dendrite formation and subsequent side reactions, unavoidably hinder the implementation of grid‐scale applications. In this study, a novel bimetallic cation‐enhanced gel polymer electrolyte (Ni/Zn‐GPE) was engineered to address these issues. The Ni/Zn‐GPE effectively disrupted the hydrogen‐bonding network of water, resulting in a significant reduction in the freezing point of the electrolyte. Consequently, the designed electrolyte demonstrates an impressive ionic conductivity of 28.70 mS cm−1 at −20°C. In addition, Ni2+ creates an electrostatic shielding interphase on the Zn surface, which confines the sequential Zn2+ nucleation and deposition to the Zn (002) crystal plane. Moreover, the intrinsically high activation energy of the Zn (002) crystal plane generated a dense and dendrite‐free plating/stripping morphology and resisted side reactions. Consequently, symmetrical batteries can achieve over 2700 hours of reversible cycling at 5 mA cm−2, while the Zn || V2O5 battery retains 85.3% capacity after 1000 cycles at −20°C. This study provides novel insights for the development and design of reversible low‐temperature zinc‐ion batteries.image

The unity of high-stability and high-performance in two-dimensional (2D) material devices has consistently posed a fundamental challenge. Halide perovskites have shown exceptional optoelectronic properties but poor stability. Conversely, oxide perovskites exhibit exceptional stability, yet hardly achieve their high photoelectric performances. Herein, for the first time, high-stability 2D perovskite LaNb2O7 (LNO) is engineered for high-performance wide-temperature UV light detection and human motion detection. High-quality LNO nanosheets are prepared by solid-state calcination and liquid-phase exfoliation technique, resulting in exceptional stability against high temperature, acid, and alkali solutions. As expected, individual LNO nanosheet device achieves ultra-wide temperature (80–780 K) and ultra-high (3.7 × 104 A W−1 at 780 K) UV light detection. Importantly, it shows high responsivity (171 A W−1), extraordinary detectivity (4 × 1012 Jones), fast speed (0.3/97 ms), and long-term stability under ambient conditions. In addition, wafer-scale LNO film devices can be used as pixel array detectors for UV imaging, and large-area flexible LNO film devices exhibit satisfactory photodetection performance after repeated bending tests. Interestingly, LNO nanosheets also exhibit distinct piezoelectric characteristics, which can serve as high-sensitivity stress sensors for human motion detection.

在二维（2D）材料设备中实现高稳定性和高性能的统一一直是一个基本挑战。卤化物类包晶石具有卓越的光电特性，但稳定性较差。与此相反，氧化物类包晶石表现出卓越的稳定性，但却难以实现其较高的光电性能。本文首次将高稳定性二维包晶 LaNb2O7（LNO）用于高性能宽温紫外光检测和人体运动检测。高质量的 LNO 纳米片是通过固态煅烧和液相剥离技术制备的，因此对高温、酸和碱溶液具有极高的稳定性。正如预期的那样，单个 LNO 纳米片器件实现了超宽温度（80-780 K）和超高（780 K 时为 3.7 × 104 A W-1）紫外光检测。重要的是，它显示出高响应度（171 A W-1）、超强检测度（4 × 1012 Jones）、快速（0.3/97 ms）以及在环境条件下的长期稳定性。此外，晶圆级 LNO 薄膜器件可用作紫外成像的像素阵列探测器，而大面积柔性 LNO 薄膜器件在反复弯曲测试后也表现出令人满意的光探测性能。有趣的是，LNO 纳米片还表现出明显的压电特性，可用作人体运动检测的高灵敏度应力传感器。这些令人鼓舞的结果可能会为二维包晶氧化物材料的创新发展及其多样化应用铺平道路。

Halide perovskites have shown exceptional optoelectronic properties but poor stability. Conversely, oxide perovskites exhibit exceptional stability, yet hardly achieve their high photoelectric performances. Herein, for the first time, high-stability 2D perovskite LaNb<sub>2</sub>O<sub>7</sub> (LNO) is engineered for high-performance wide-temperature UV light detection and human motion detection. High-quality LNO nanosheets are prepared by solid-state calcination and liquid-phase exfoliation technique, resulting in exceptional stability against high temperature, acid, and alkali solutions. As expected, individual LNO nanosheet device achieves ultra-wide temperature (80–780 K) and ultra-high (3.7 × 10<sup>4</sup> A W<sup>−1</sup> at 780 K) UV light detection. Importantly, it shows high responsivity (171 A W<sup>−1</sup>), extraordinary detectivity (4 × 10<sup>12</sup> Jones), fast speed (0.3/97 ms), and long-term stability under ambient conditions. In addition, wafer-scale LNO film devices can be used as pixel array detectors for UV imaging, and large-area flexible LNO film devices exhibit satisfactory photodetection performance after repeated bending tests. Interestingly, LNO nanosheets also exhibit distinct piezoelectric characteristics, which can serve as high-sensitivity stress sensors for human motion detection. These encouraging results may pave the way for more innovative advances in 2D perovskite oxide materials and their diverse applications.","PeriodicalId":48538,"journal":{"name":"Infomat","volume":null,"pages":null},"PeriodicalIF":22.7,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141883263","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}
Solid-state Li metal battery has attracted increasing interests for its potentially high energy density and excellent safety assurance, which is a promising candidate for next generation battery system. However, the low ionic conductivity and Li+ transport number of solid-state polymer electrolytes limit their practical application. Herein, a composite polymer electrolyte with self-inserted structure is proposed using the layered double hydroxides (LDHs) as dopant to achieve a fast Li+ transport channel in poly(vinylidene-co-trifluoroethylene) [P(VDF-TrFE)] based polymer electrolyte. In such a composite electrolyte, P(VDF-TrFE) polymer has an all-trans conformation, in which all fluorine atoms locate on one side of the polymer chain, providing fast Li+ transport highways. Meanwhile, the LDH can immobilize the anions of Li salts based on the electrostatic interactions, promoting the dissociation of Li salts, thereby enhancing the ionic conductivity (6.4 × 10−4 S cm−1) and Li+ transference number (0.76). The anion immobilization effect can realize uniform electric field distribution at the anode surface and suppress the dendritic Li growth. Moreover, the hydrogen bonding interaction between LDH and polymer chains also endows the composite electrolyte with strong mechanical properties. Thus, at room temperature, the Li || Li symmetric cells can be stably cycled over 1000 h at a current density of 0.2 mA cm−2, and the full cells with LiFePO4 cathode deliver a high capacity retention (>95%) after 200 cycles. This work offers a promising route to construct solid-state polymer electrolytes with fast Li+ transport.
固态锂金属电池因其潜在的高能量密度和出色的安全保证而受到越来越多的关注，是下一代电池系统的理想候选材料。然而，固态聚合物电解质较低的离子电导率和 Li+ 迁移次数限制了其实际应用。本文提出了一种具有自嵌式结构的复合聚合物电解质，以层状双氢氧化物（LDHs）为掺杂剂，在聚（亚乙烯基-共三氟乙烯）[P(VDF-TrFE)]基聚合物电解质中实现快速的 Li+ 传输通道。在这种复合电解质中，P(VDF-TrFE) 聚合物具有全反式构象，其中所有的氟原子都位于聚合物链的一侧，从而提供了快速的 Li+ 传输通道。同时，基于静电作用，LDH 可以固定 Li 盐的阴离子，促进 Li 盐的解离，从而提高离子电导率（6.4 × 10-4 S cm-1）和 Li+ 迁移数（0.76）。阴离子固定效应可在阳极表面实现均匀的电场分布，抑制树枝状锂的生长。此外，LDH 与聚合物链之间的氢键作用还赋予了复合电解质很强的机械性能。因此，在室温条件下，锂||锂对称电池可在 0.2 mA cm-2 的电流密度下稳定循环 1000 小时，而采用磷酸铁锂阴极的全电池在循环 200 次后可实现较高的容量保持率（95%）。这项工作为构建具有快速锂+传输能力的固态聚合物电解质提供了一条前景广阔的途径。
