Synthesis, Characterization, and Biological Activities of Fe‐ and V‐Doped and Co‐Doped TiO 2

Doping and co‐doping of TiO 2 nanoparticles was performed using iron and vanadium by an impregnation method and the as‐synthesized samples were characterized. The redesigned photocatalyst mainly covered the anatase phase in the presence of metal ions in the lattice of the TiO 2 photocatalyst. The UV‐vis extinction coefficient and Raman spectroscopy revealed a redshift with an increase in the concentration of metal ions. The synthesized photocatalysts did not change the shape of the nanoparticles. The anticancer and antibacterial activities were checked using doped and co‐doped TiO 2 nanoparticles on a lung cancer cell line and E. coli , respectively. The results indicated effective cell inhibition using the co‐doped TiO 2 nanoparticles and maximum antibacterial activity in TiO 2 doped with ferric ions.
