High-entropy oxides provide a powerful platform for engineering mechanically driven catalysis, yet their underlying mechanisms remain poorly understood. Here, we investigate the catalytic performance of high-entropy perovskites, Sr(Ti, Zr, Hf, Sn, Nb)O3 (STZHSN) and Pb(Mg, Nb, Zr, Ti, Hf)O3 (PMNZTH), alongside single-component oxides SrTiO3 (STO) and BiFeO3 (BFO), revealing a clear correlation between compositional complexity and activity. PMNZTH exhibited the highest catalytic efficiency, followed by STZHSN and STO, with BFO performing the least effectively. Using combined ultrasonic and blade-induced agitation, we show that fluid turbulence and solid–liquid interfacial dynamics critically enhance charge transfer. Spectroscopic and theoretical analyses indicate that surface hydroxyl groups facilitate the formation of reactive oxygen species, while cavitation and friction drive a self-sustaining redox cycle. These insights culminate in a unified surface-electrostatics-driven catalysis model, where interfacial surface potential, hydroxyl adsorption, and turbulence-enhanced charge transport govern the activity beyond intrinsic piezoelectric effects. This study establishes high-entropy design as a versatile strategy for optimizing mechanically driven catalysts for energy conversion and environmental remediation.
高熵氧化物为工程机械驱动催化提供了一个强大的平台,但其潜在的机制仍然知之甚少。在这里,我们研究了高熵钙钛矿,Sr(Ti, Zr, Hf, Sn, Nb)O3 (STZHSN)和Pb(Mg, Nb, Zr, Ti, Hf)O3 (PMNZTH)以及单组分氧化物SrTiO3 (STO)和BiFeO3 (BFO)的催化性能,揭示了成分复杂性和活性之间的明确相关性。PMNZTH的催化效率最高,其次是STZHSN和STO, BFO的催化效率最低。利用超声和叶片诱导搅拌相结合的方法,我们发现流体湍流和固液界面动力学极大地增强了电荷传递。光谱和理论分析表明,表面羟基促进了活性氧的形成,而空化和摩擦驱动了一个自我维持的氧化还原循环。这些见解最终形成了一个统一的表面静电驱动的催化模型,其中界面表面电位、羟基吸附和湍流增强的电荷输运控制着固有压电效应之外的活性。本研究建立了高熵设计作为优化能量转换和环境修复的机械驱动催化剂的通用策略。

Triboelectric nanogenerators (TENGs) continue to serve as promising candidates to harvest micromechanical energy from ambient sources and convert into useful electrical energy for meeting the globally increasing energy demands. However, the output from TENG is pulsed alternating current (AC) with high crest factor, often unsuitable for directly powering electronic devices. This necessitates the need for additional rectification measures, such as a rectifier bridge, diode, etc. which reduces the energy utilization efficiency and portability of the TENG. Novel frictional materials and designs have enabled the generation of direct current (DC) output based on the conjunction of semiconductor technology and contact electrification. This emerging class of energy harvesting materials is termed as tribovoltaic nanogenerators (TVNGs). This review provides an overview of this important technology, collating the important developments and future insights. We start by a general introduction of TVNGs, elucidating its mechanism, dynamic interface upon friction, and output performance. We then delve into the different materials and device configurations of TVNGs, such as metal-semiconductor, semiconductor- semiconductor, insulator-based and liquid-interfaces. We then discuss the factors affecting the performance of TVNGs and possible solutions to design efficient TVNGs. We finally conclude by elucidating the recent developments in TVNGs, the grand challenges incurred, and proposing future solutions to accelerate the development of more efficient TVNGs concurrent with increasing energy demands.
摩擦电纳米发电机(TENGs)继续作为有希望的候选者从环境源中收集微机械能,并将其转化为有用的电能,以满足全球日益增长的能源需求。然而,从TENG输出脉冲交流电(AC)与高波峰系数,往往不适合直接为电子设备供电。这就需要额外的整流措施,如整流桥、二极管等,从而降低了TENG的能源利用效率和便携性。基于半导体技术和接触电气化的结合,新型摩擦材料和设计使产生直流(DC)输出成为可能。这种新兴的能量收集材料被称为摩擦伏打纳米发电机(tvng)。本文综述了这一重要技术,整理了重要的发展和未来的见解。我们首先概述了tvng,阐明了它的机理、摩擦的动态界面和输出性能。然后,我们深入研究了不同的材料和器件结构,如金属半导体,半导体-半导体,基于绝缘体和液体界面。然后,我们讨论了影响tvng性能的因素以及设计高效tvng的可能解决方案。最后,我们阐明了tvng的最新发展、面临的重大挑战,并提出了未来的解决方案,以加速开发更高效的tvng,同时满足不断增长的能源需求。

Band alignment has been extensively utilized in thermoelectric materials to enhance carrier mobility and suppress lattice thermal conductivity. However, its impact on ionic transport in superionic conductors remains largely unexplored. In such systems, the migration of Cu ions complicates carrier and phonon transport since the additional scattering effects and ionic conductivity. Herein, we propose a novel path of in-situ forming endotaxial CsPbBr3 nanoprecipitates within a Cu1.96S matrix. It is found that the valence band alignment and crystallographic coherence facilitate carrier mobility. The endotaxial nanostructures decrease ionic conductivity and lattice thermal conductivity by Cu ion suppression and all-scale phonon scattering enhancement. Consequently, a peak ZT of 2.4 is realized in Cu1.96S-1.16 vol% CsPbBr3 specimen at 973 K. This approach offers a novel framework for regulating carrier, phonon, and ion transport, with significant potential for advancing thermoelectrics and other functional material systems.
带对准已广泛应用于热电材料,以提高载流子迁移率和抑制晶格热导率。然而,它对超离子导体中离子输运的影响在很大程度上仍未被探索。在这样的系统中,由于额外的散射效应和离子电导率,Cu离子的迁移使载流子和声子的输运复杂化。在此,我们提出了一种在Cu1.96S基体中原位形成内源性CsPbBr3纳米沉淀的新途径。发现价带排列和晶体学相干有利于载流子迁移。内源性纳米结构通过抑制Cu离子和增强全尺度声子散射来降低离子电导率和晶格热导率。因此,在973 K时,Cu1.96S-1.16 vol.% CsPbBr3样品的ZT峰值为2.4。这种方法为调节载流子、声子和离子输运提供了一种新的框架,具有推进热电和其他功能材料系统的巨大潜力。

Dual-atom catalysts (DACs) have emerged as a frontier in electrocatalysis, offering unique active site geometries and exceptional performance across diverse electrochemical reactions. However, simultaneously achieving high metal loading while maintaining atomic precision in diatomic site synthesis remains a critical challenge. Here, we report a host-guest nested architecture strategy to synthesize high-loading dual-atom Fe catalysts with atomic precision. By leveraging graphdiyne (GDY)’s electron-rich sp-carbon bonding network and intrinsic triangular cavities as a host matrix, we covalently embed Fe2(CO)9 guest molecules into its voids, enabling precise nesting of Fe2 pairs at cavity centers. The resulting Fe2-N-GDY catalyst achieves an ultra high diatomic Fe loading of 16.2 wt%, while maintaining a well-defined 2.6 Å Fe-Fe spacing. This structure delivers exceptional oxygen reduction reaction (ORR) performance, with a half-wave potential of 0.92 V and limiting current density of 6.0 mA cm−2. In situ characterization reveal that due to the form of paired atoms, atomic Fe sites synergistically reduce the O-O bond cleavage energy barrier, accelerating the *OOH → *O + *OH conversion pathway and enhancing 4-electron selectivity. This work provides a route for designing high-loading DACs and elucidating their reaction mechanisms in electrochemical catalysis via targeted host-guest nested engineering, with insights into their structure performance relationships.
双原子催化剂(dac)已成为电催化领域的前沿,在不同的电化学反应中具有独特的活性位点几何形状和卓越的性能。然而,在双原子位合成中,如何在保持原子精度的同时实现高金属负载仍然是一个关键的挑战。在这里,我们报告了一种主客嵌套架构策略来合成具有原子精度的高负载双原子铁催化剂。通过利用石墨炔(GDY)的富电子sp-碳键网络和固有的三角形空腔作为宿主基质,我们将Fe2(CO)9客体分子共价嵌入到其空腔中,实现了Fe2对在空腔中心的精确嵌套。所得的Fe2-N-GDY催化剂实现了16.2 wt.%的超高双原子铁负载,同时保持了明确的2.6 Å Fe-Fe间距。该结构具有出色的氧还原反应(ORR)性能,半波电位为0.92 V,极限电流密度为6.0 mA cm-2。原位表征表明,由于成对原子的形式,原子Fe位点协同降低了O-O键的裂解能垒,加速了*OOH→*O + *OH的转化途径,提高了4电子的选择性。这项工作为设计高负载dac提供了一条途径,并通过目标主客体嵌套工程阐明其在电化学催化中的反应机制,并深入了解其结构性能关系。

Alluaudite-type Na2.6Fe1.7(SO4)3 is a promising high-voltage cathode material for sodium-ion batteries (SIBs), whose practical application is severely hindered by intrinsic structural instability. To overcome this limitation, high-charge-density Ti4 + was incorporated into the Fe site to stabilize the lattice framework by modulating local electron distribution and mitigating Na+ enrichment. Cationic rearrangement is effectively suppressed, primarily attributed to the Ti-induced regulation of the local Na+ distribution, as revealed by CV. Furthermore, b-axis lattice distortion is remarkedly alleviated owing to the strong covalent nature of Ti-O bonds, which enhances structural stability accompanied with the introduction of the metastable FeNaO10 framework, as confirmed by in-situ XRD measurements. Consequently, a high specific capacity of 71.68 mAh g−1 was observed at 20 C, with 75.22 % capacity retention after 6000 cycles, and 49.19 mAh g−1 was retained at −20 °C under 2 C conditions. Overall, this strategy effectively enables structural stabilization and demonstrates a widely applicable and generalizable approach for advancing high-performance SIBs.
冲积型Na2.6Fe1.7(SO4)3是一种很有前途的钠离子电池高压正极材料,但其固有的结构不稳定性严重阻碍了其实际应用。为了克服这一限制,将高电荷密度Ti4 +掺入Fe位点,通过调节局部电子分布和减轻Na+富集来稳定晶格框架。CV显示,阳离子重排被有效抑制,这主要归因于ti诱导的局部Na+分布的调节。此外,原位XRD测量证实,由于Ti-O键的强共价性质,b轴晶格畸变明显减轻,随着介稳FeNaO10框架的引入,结构稳定性增强。结果表明,在20 ℃条件下,电池的比容量高达71.68 mAh g−1,在6000次循环后,电池容量保持率为75.22 %,在2 ℃条件下,电池在- 20℃条件下的比容量保持率为49.19 mAh g−1。总体而言,该策略有效地实现了结构稳定性,并为推进高性能sib展示了一种广泛适用和可推广的方法。

To overcome this limitation, high-charge-density Ti<sup>4 +</sup> was incorporated into the Fe site to stabilize the lattice framework by modulating local electron distribution and mitigating Na<sup>+</sup> enrichment. Cationic rearrangement is effectively suppressed, primarily attributed to the Ti-induced regulation of the local Na<sup>+</sup> distribution, as revealed by CV.
