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

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..., The dataset for this study was collected through data acquisition from analytical instruments. , , # Data from: Microwave-assisted graphene oxide/carbon spheres with silver nanoparticles: Dual catalyst for peroxide detection and antibacterial use

## 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 visual...,
