Synthesis of Tungsten Oxide Nanoflakes and Their Antibacterial and Photocatalytic Properties

This current work revealed a single-step fabrication of tungsten oxide nanoflakes (WO3 NFs) with the help Terminalia arjuna bark extract. Bioactive phytoconstituents T. extract were involved in nucleation process and promoted material crystalline growth particular direction. The as-prepared sample thermal decomposition was analyzed by TG/DTG. annealed at 300 °C for 2 h, characterized UV-Vis-DRS, FTIR, Raman, XRD, SEM, EDX, TEM. Synthesized WO3 samples showed monoclinic phase flake-like structure lengths 25~230 nm diameters 25~120 nm. NFs evaluated against S. aureus E. coli. Over 3 mg concentrations outperform positive control antibacterial activity. pseudo-first-order kinetics enhanced photocatalytic performance methylene blue (MB). These results prove that have sustainable MB degradation applications.
