title: Data from: Microwave-assisted graphene oxide/carbon spheres with silver nanoparticles: Dual catalyst for peroxide detection and antibacterial use

description: 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.

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. ### Files and variables #### File: Dataset.zip **Description:** This dataset file contains the data and descriptions of all experimental parameters required to construct the charts and graphs presented in the manuscript and supplementary material.
