| Sumario: | The present study reported biofabrication of flower-like SnO<sub>2</sub> nanoparticles using <i>Pometia pinnata</i> leaf extract. The study focused on the physicochemical characteristics of the prepared SnO<sub>2</sub> nanoparticles and its activity as photocatalyst and antibacterial agent. The characterization was performed by XRD, SEM, TEM, UV-DRS and XPS analyses. Photocatalytic activity of the nanoparticles was examined on bromophenol blue photooxidation; meanwhile, the antibacterial activity was evaluated against <i>Klebsiella pneumoniae</i>, <i>Escherichia coli Staphylococcus aureus</i> and <i>Streptococcus pyogenes</i>. XRD and XPS analyses confirmed the single tetragonal SnO<sub>2</sub> phase. The result from SEM analysis indicates the flower like morphology of SnO<sub>2</sub> nanoparticles, and by TEM analysis, the nanoparticles were seen to be in uniform spherical shapes with a diameter ranging from 8 to 20 nm. SnO<sub>2</sub> nanoparticles showed significant photocatalytic activity in photooxidation of bromophenol blue as the degradation efficiency reached 99.93%, and the photocatalyst exhibited the reusability as the degradation efficiency values were insignificantly changed until the fifth cycle. Antibacterial assay indicated that the synthesized SnO<sub>2</sub> nanoparticles exhibit an inhibition of tested bacteria and showed a potential to be applied for further environmental and medical applications. |
