Anion doping in cobalt-based catalysts can modulate catalytic performance by altering the coordination environment and electronic structure of active sites, thereby affecting surface reconstruction and reaction kinetics. Here, anion-modified cobalt hydroxysalts [Co(OH)2-x(Am-)x/m, A = CO32-, F-, Cl-] were synthesized to investigate anion-specific effects on electrooxidation of 5-hydroxymethylfurfural. The carbonate-incorporated nanowire catalyst exhibited outstanding performance, lowering the oxidation potential to 1.33 V at 50 mA cm-1 and increasing the active site density by 1.5 times relative to undoped Co(OH)2. In contrast, F- and Cl- doping led to redox potential shifts and reduced activity. In situ Raman spectroscopy revealed that the catalytic reaction was driven by active CoOOH species generated under anodic polarization. This process was accompanied by carbonate leaching and irreversible phase changes, which contributed to catalyst deactivation. This study provides insights into anion-controlled catalyst design for efficient and durable biomass electrooxidation.","PeriodicalId":713,"journal":{"name":"Nano Research","volume":"19 3","pages":"94908223-94908223"},"PeriodicalIF":0.0,"publicationDate":"2025-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ruthenium (Ru)-based catalysts exhibit Pt-like activity at a fraction of the cost, but their performance is hampered by excessive hydroxide accumulation on Ru sites, a consequence of their overly strong oxygen affinity and suboptimal d-band center. Herein, we reported a class of Mo/V-dual-tailored Ru metallic glass nanosheets (Mo/V-Ru NSs) to enable spatial segregation of water dissociation sites (on Mo/V) from hydrogen evolution sites (on Ru), achieving the acceleration of alkaline HER electrocatalysis. The optimized Mo/V-Ru NSs deliver outstanding alkaline HER performance, with overpotentials of 36 mV and 86 mV at 10 and 100 mA cm⁻2, respectively, outperforming pure Ru counterparts and commercial Pt/C. Remarkably, the Mo/V-Ru NSs-based AEMWE can achieve a high current density of 100 mA cm−2 at a low cell voltage of 1.68 V and exhibit excellent durability for over 120 h.

In this study, a Co-MOF@CNTs precursor was converted into a composite of Co nanoparticles embedded in defective porous carbon nanotubes (Co@CNTs-800). The resulting Co@CNTs-800/PMS system exhibited remarkable catalytic activity in the degradation of rhodamine B (RhB), achieving complete degradation within 4 minutes with a rate constant of 1.025 min-1. The material demonstrated excellent stability across a broad pH range (pH = 4~10) and exhibited high performance in the presence of common inorganic anions (Cl⁻ and NO₃⁻) as well as natural organic matter, with maintained stability over 6 cycles. Quenching assays and electron paramagnetic resonance (EPR) spectroscopy revealed that both free radical (SO4•–, •OH, and O2•–) and non-radical (1O2 and charge transfer) pathways contribute to the degradation process, with non-radical mechanisms dominated by 1O2. The degradation pathway of RhB was elucidated based on intermediates detected by liquid chromatography-mass spectrometry (LC-MS) and density functional theory (DFT) calculations.

Most contemporary wound repair materials passively release loaded drugs, resulting in poor therapeutic outcomes. In this study, we designed sequentially triggered triple-responsive hydrogels containing alginate (ALG)-phenylboronic acid (PBA), copper polydopamine (Cu-PDA), metformin (MET), and deferoxamine mesylate (DFO) to cover the continuous process of diabetic-infected wound healing and improve the wound microenvironment through warming in the infectious phase and on-demand drug release in the inflammatory and proliferative phase. The hydrogels exhibited good adhesivity, injectability, self-healing ability, and biocompatibility. The hydrogels show remarkable photothermal responsiveness due to the presence of PDA. Studies showed that appropriate high temperatures and the release of Cu2+ resulted in the hydrogels displaying excellent bactericidal properties in the infectious phase. Furthermore, the instability of the phenyl borate bond in a hyperglycemic and acidic microenvironment enables the glucose/pH responsiveness of the release of MET and DFO from the hydrogels. Mechanistic studies have shown that the hydrogels could suppress the activity of the NOD-, LRR-, and pyrin structural domain-containing protein 3 (NLRP3)/caspase-1/GasderminD (GSDMD)/IL-1β pathway and activate the hypoxia-inducible factor 1 alpha (HIF-1α)/vascular endothelial growth factor (VEGF) pathway.
