摘要
双金属纳米粒子因其独特的性质和多样化的应用而在众多领域具有重要意义。本研究采用简单的湿化学方法合成了银（Ag）和钴（Co）单金属纳米粒子（MNPs）和银钴双金属纳米粒子（BNPs）。在确认 BNPs 时采用了多种分析技术。粉末 X 射线衍射 (PXRD) 分析显示形成了 FCC 结构。透射电子显微镜（TEM）显微照片证实了双金属性质和 Janus 结构。合成的纳米粒子在降解 4-硝基苯酚染料方面表现出更高的催化活性。认识到金属纳米粒子在显著提高三电纳米发电机（TENG）效率方面的潜力，将合成的 AgCo 双金属纳米粒子与聚合物基体结合，细致分析了其对三电性能的影响。有趣的是，8 毫升双金属纳米粒子复合量较高的 TENG 表现出更高的性能，可产生约 270.52 V 的输出电压和 5.24 µA 的电流。因此，所获得的增效 BNPs 在水处理和能量收集应用方面都显示出了广阔的前景。
Robust Ag-Co bimetallic nanoparticles: Dual role in catalytic and triboelectric performance
Bimetallic nanoparticles are of great significance in numerous areas due to their unique properties and diverse applications. In the present study, silver (Ag) and cobalt (Co) monometallic nanoparticles (MNPs) and AgCo bimetallic nanoparticles (BNPs), are synthesized using a simple wet chemical route. Various analytical techniques are adopted for the confirmation of the BNPs. Powder X-ray diffraction (PXRD) analysis revealed the formation of FCC-structure. Transmission Electron Microscopy (TEM) micrographs confirmed the bimetallic nature and Janus structure. The synthesized nanoparticles exhibit higher catalytic activity for degrading 4-nitrophenol dye. Recognizing the potential of metal nanoparticles to significantly boost the efficiency of triboelectric nanogenerators (TENG), the synthesized AgCo bimetallic nanoparticles are incorporated into polymer matrix to meticulously analyze the impact on the triboelectric performance. Interestingly, TENG with a higher composite quantity of 8 ml BNPs exhibited greater performance, generating an output voltage of about 270.52 V and a current of 5.24 µA. Hence, the procured synergistic BNPs show their promising avenue towards both water treatment and energy harvesting applications.
期刊介绍：
Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
