Ni-HCF nanocubes were tested to remove metronidazole (MDZ), a water contaminant antibiotic. Under simulated solar light, Ni-HCF display substantial photocatalytic activity, degrading 94.3% of MDZ in 6 hours. These achievements highlight the possibility to combine the performance of an earth-abundant catalysts with a renewable energy source for environmental remediation, thus meeting the requirements for a sustainable development.\u0000\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture>\u0000 </div>\u0000 </figure>","PeriodicalId":229,"journal":{"name":"Small Methods","volume":"9 2","pages":""},"PeriodicalIF":10.7,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/smtd.202570012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455818","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}

This work uses CoNi-MOF (metal-organic framework) as a self-template to yield the CrS doped CoNi/C bifunctional catalyst. Comparable to Pt/C and IrO2 commercial catalysts, the CrS@CoNi/C catalyst exhibits improved electrocatalytic activity toward OER and ORR due to its linked pellet architecture and intact metal sulfide@carbon structure. The CrS@CoNi/C catalyst has the most intriguing ORR/OER performance, with a significantly lower potential and an exceptionally extended cycle duration (E1/2 = 0.72 V and η10 = 260 mV). The CrS@CoNi/C-based aqueous zinc-air battery shows long-term charge-discharge stability (more than 100h/600 cycles) together with significant specific capacity (789.7 mAh g-1 Zn) and power density (132.2 mW cm-2). Most significantly, after charge-discharge stability, the recharged CrS@CoNi/C-based alkaline zinc-air battery has been employed to exhibit less structural deformation for the cathode and more zincate ion production for the anode side electrodes, which is employed through TEM analysis.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2401515"},"PeriodicalIF":10.7,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, methods for synthesizing multilayer graphene films or graphite on single-crystal nickel foils are developed. However, the chemical vapor deposition (CVD) synthesis of thick-layer graphene films or graphite (TLG) on copper substrates remains a significant challenge due to the self-limiting growth phenomenon. In this study, a novel method to grow TLG on copper substrates by controlling the silicon additive is presented. The as-grown TLG exhibits high quality, with controllable thickness from a few layers to tens of nanometers. The growth of TLG films is achieved by the synchronous growth of multilayer graphene islands on a silicide copper surface, which is likely to be in a liquid state according to the Cu-Si phase diagram. On the Cu-Si surface, all graphene layers grow synchronously, circumventing the self-limiting mechanism and the antiwedding cake growth or wedding cake mode of van der Waals material growth. Based on this synchronous growth mode, the thickness of TLG can be precisely controlled, ranging from a few to tens of nanometers. The study provides a facile and scalable way to synthesize high-quality thick vdW films for various applications.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2402129"},"PeriodicalIF":10.7,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The configuration of the PBC and its topology significantly influence the thermal conduction of cellular structures and the thermal storage properties of PCMs. This study develops a framework for multiscale topology optimization of cellular structures, which can first determine the optimal configuration for PBCs and then their optimal density distribution. The optimized topology structure is tree-like, as shown by the hierarchical pores formed by PBCs with varying densities. This hierarchical cellular structure successfully reduces the maximum temperature by 22%, improves the temperature uniformity by 9%, and shortens the melting time by 8% compared to the unoptimized structure. Cellular structures with different topology structures are selective-laser-melting 3D-printed to encapsulate paraffin wax, which experimentally validates that the hierarchical structure can shorten the melting time by 10.4% compared to a uniform structure, even if their porosity is the same. This progress breaks through the conventional concept that the effective thermal conductivity of the cellular structure cannot be modulated once its porosity is fixed and opens up a new idea to improve the melting behavior of PCMs.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2402089"},"PeriodicalIF":10.7,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the key problems of AZBs are the uncontrollable zinc dendrites growth and water-induced erosion faced by zinc anodes. Therefore, reducing the hydrophilicity of zinc anode and introducing the zincophilic sites are the availably strategy. Herein, 3D highly-conductive host is developed to inhibit Zn dendrites growth, which have a porous structure consisting of graphene and carbon nanotubes embedded with a zincophilic nucleation sites of Zn Prussian blue analogs (ZnHCF@3D-GC). The inner ZnHCF possess minimized nucleation barriers, which can serve as favorable nucleation sites, and 3D host provide a buffer interspace to allow for even more high-capacity Zn plating. Additionally, density functional theory results show that ZnHCF exhibits a strong Zn binding energy and high adsorption energy of Zn (002) plane, which can guide Zn horizontal deposition in the 3D host. As a result, the assembled symmetrical cell is able to stabilize 900 cycles at an ultrahigh current density of 100 mA cm-2.
