Abstract
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.
