A Brief Review of Transition Metal Doped TiO2 Nanoparticles for Dye-Contaminated Wastewater Treatment

Subhash Chandra, Mahendra Kumar Gora, Arvind Kumar, Sanjay Kumar

Abstract: Transition metal-doped TiO2 nanoparticles have gained significant interest for their enhanced photocatalytic performance in degrading dyes from contaminated wastewater. Doping with transition metals like Fe, Cu, Mn, Sr, and Zn modifies the electronic and optical properties of TiO2 reducing its bandgap and improving its light absorption into the visible spectrum. This review explores the impact on photocatalytic efficiency of TiO2 nanoparticles focusing on factors such as charge carrier separation, surface activity, and dye degradation rates when transition metal doping is done with TiO2 nanoparticles. The review emphasizes the potential of transition metal doped TiO2 nanoparticles as economical and ecofriendly materials for treating dye-contaminated water, supporting sustainable wastewater management methods.
