However, conventional MOFs often have insufficient catalytic activity and Li<sup>+</sup> transport control, and the role of their internal pore structure in regulating Li<sup>+</sup> flux and polysulfide conversion remains unclear, limiting their effectiveness as high-performance separators. Herein, we report a series of azolate hybrid frameworks (M-AHF-DPDC, M = Fe, Co, Ni) featuring one-dimensional anionically charged channels that implement a dual-function regulation mechanism, simultaneously promoting uniform Li<sup>+</sup> flux and catalyzing polysulfide conversion. Incorporation of Fe centers significantly enhances polysulfide redox kinetics, resulting in superior electrochemical performance, including a high initial capacity of 1400.7 mAh g<sup>−1</sup> and stable cycling over 700 cycles at 1 C, along with uniform Li<sup>+</sup> deposition, outperforming most reported MOF-based separators. Density functional theory calculations confirm that Fe sites strongly adsorb and catalytically convert diverse polysulfides, promoting rapid sulfur species transformation.

Notably, single-junction semiconductor photocathodes are attractive due to their structural simplicity, cost-effectiveness, and mature fabrication, yet they usually exhibit intrinsically poor carrier extraction efficiency. To address this challenge, we propose a synergistic “dual-electron extraction” strategy that fully unleashes the hydrogen evolution potential of single-junction p-InGaN nanowires. Remarkably, the optimized p-InGaN photocathode achieves a photocurrent density of −3.40 mA cm<sup>−2</sup> at 0 V vs. RHE—representing a 37.8-fold enhancement over the pristine device—with an onset potential of 0.82 V vs. RHE, while sustaining stable hydrogen generation for over 300 h without additional protective layers. Specifically, an electron-blocking layer was incorporated within p‑InGaN nanowires to suppress electron backflow toward the substrate and promote transport to the nanowire/electrolyte interface. Furthermore, surface anion doping in InGaN nanowires significantly enhances the band bending of InGaN, which promotes interfacial electron transfer while simultaneously optimizing hydrogen adsorption energy, thereby accelerating the hydrogen evolution reaction rate. The proposed synergistic dual-electron extraction strategy markedly improves the electron utilization efficiency of single-junction InGaN nanowires, providing a novel pathway to address the intrinsic limitations of wafer-scale III-V nitride photoelectrodes. </p><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"18 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02186-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147702250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the structural complexity and multifunctionality of these molecules demand catalysts capable of multisite activation and precise chemo-selectivity. High-entropy catalysts (HECs), which integrate five or more principal elements into a single phase, have recently emerged as a promising materials platform, offering tunable active sites, enhanced stability, and unique synergistic effects. This review provides a comprehensive and up‑to‑date overview of recent advances in HECs for the valorization of biomass‑derived chemicals. We first clarify the definition of high‑entropy materials and elucidate the relationships between the four core effects and catalytic performance. Subsequently, we systematically outline the key elements frequently incorporated in HECs, emphasizing their roles in modulating active sites and electronic structures. Design strategies, including component modulation, morphology/size regulation, defect engineering, and heterostructure construction, are discussed with a focus on synergistic mechanisms governing biomass conversion. The applications of HECs in major valorization reactions, including oxidation of 5-hydroxymethylfurfural (HMF), hydrogenation of HMF and furfural (FF), oxidative condensation of FF, depolymerization of lignin, and conversion of glucose and glycerol are detailed, highlighting clear correlations between catalyst structure and catalytic efficacy. Finally, we identify prevailing challenges and outline future research directions aimed at the rational design of next-generation HECs for efficient and selective biomass upgrading. This work aims to serve as a foundational reference and stimulate further innovation in the application of HECs in biorefinery and green chemistry.</p><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"18 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02192-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147684817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
