Ultrasound-assisted Self-Assembly Synthesis of WO3 Nanoparticles and Its Photocatalytic Study for Tetracycline Photooxidation

The existing work demonstrated the successful synthesis of WO3 nanoparticles in one-pot system via self-assembly synthesis using triton-X as non-ionic polymer templating agent. The fast and efficient method was achieved by ultrasound irradiation. Characterization by using XRD, FTIR, XPS, UV-DRS, SEM, TEM and HRTEM demonstrated the formation of pure WO3 having particle size of 10-25 nm. With the band gap energy of 2.25 eV, the prepared nanoparticles showed excellent photocatalytic performance towards tetracycline photooxidation with removal of 91.84 % during 60 of treatment.
