Pioneering action of photocatalytic and antibacterial behaviors of BaSnO3/rGO/Ag nanocomposites

Abstract

Currently, designed materials consist of efficient, cost-effective, and sustainable photocatalysts that alleviate the constant crisis of environmental pollution for enormous interest. Hither, synthesized a new classification of perovskite-type BaSnO₃/rGO/Ag nanocomposites by hydrothermal method. The structure and morphology of the samples were investigated through XRD, FT-IR, Raman, diffuse reflectance spectra (UV–Vis DRS), and SEM morphological analyses. XRD results revealed that BaSnO₃ has a cubic crystalline phase. SEM morphological analysis of BaSnO₃/rGO/Ag nanocomposites exhibits a swing-dangle toy-like structure. The calculated band gap energies of BaSnO₃, BaSnO₃/rGO, and BaSnO₃/rGO/Ag nanocomposites are 3.4 eV, 3.3 eV, and 3.06 eV, respectively, indicating the enhanced efficiency of the BaSnO₃/rGO/Ag nanocomposites. The M–O vibrational modes were confirmed in the range of 400 to 700 cm⁻¹ and were further utilized in degradation studies, achieving 88% degradation within 80 minutes for the final sample. Moreover, the synthesized samples were tested for photocatalytic and antimicrobial activities. This research may provide some insights into the design of practical nano-photocatalytic and antibacterial materials.
