Abstract Ta2O5 nanoparticles were synthesized by ultrasound-assisted method. The prepared nanoparticles were characterized structurally by XRD, Raman and morphologically by SEM and TEM. From the XRD pattern, orthorhombic phase Ta2O5 was observed. Raman studies confirm the presence of Ta O at 613 cm−1. TEM images show the average particle size of about 21 nm. Band gap of Ta2O5 nanoparticles were carried out by UV-DRS and found to be 3.12 eV. Photocatalytic activity of Ta2O5 nanoparticles have been examined for the degradation of methylene blue dye and shows 96% degradation after 2 h under visible light irradiation. Ta2O5 nanoparticles also exhibited good antibacterial activity against the foodborne pathogens and anti-breast cancer (MCF-7: IC50: 45.04 μg/mL) activity.
