摘要

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.
