Abstract
The work was designed for the construction of AgNPs@Cs-Ta@GO nanocomposite, which involves incorporating silver nanoparticles into carbon spheres and then distributing them on graphene oxide. The fabrication process was expedited using a microwave-assisted technique. The nanocomposite with the core based on silver nanoparticles with an average diameter of 21 ± 12 nm showed significant peroxidase-like activity by oxidizing 3,3’,5,5’-tetramethylbenzidine to its oxidized form in the presence of H2O2. This compassionate H2O2 colorimetric detection allowed for quick identification of H2O2 in a broad range (0.6 ppm - 9.0 ppm) with a low detection limit of 0.2 ppm (S/N = 3). The viability of this method was confirmed by qualitatively detecting H2O2 residual in aquaculture water samples. Additionally, antibacterial tests showed strong inhibitory effects on Vibrio parahaemolyticus ATCC 17802 (gram-negative) and Staphylococcus aureus ATCC 25923 (gram-positive) with antibacterial zones of 46.1 ± 0.11 mm and 49.3 ± 0.17 mm, respectively, at a composite concentration of 50 ppm. The rapid microwave-assisted incorporation of silver nanoparticles into carbon spheres within the graphene oxide network not only improves synthesis duration but also the catalytic and antibacterial performances thanks to minimizing coagulation and promoting electron transfer on the silver nanoparticles' surface.

Description of the data and file structure
The data was collected as part of experimental efforts to characterize the properties and evaluate the performance of the materials under study. High-Resolution Transmission Electron Microscopy (HR-TEM) was employed to examine the microstructure and morphology of the samples at the nanoscale. X-Ray Diffraction (XRD) was used to analyze the crystallographic structure and phase composition. Fourier Transform Infrared Spectroscopy (FTIR) provided information on the functional groups and chemical bonding. UV-Vis spectroscopy was conducted to study peroxide detection using the colorimetric method. Additionally, antimicrobial experiments were carried out, and photographic evidence of the results was captured to visually assess the inhibitory effects against microbial growth.
These comprehensive experimental techniques ensured a thorough understanding of both the physical and functional properties of the materials.
