Titanium Dioxide Nanomaterials and its Derivatives in the Remediation of Water: Past, Present and Future

The aim of this review article is to summarize the role of titanium oxide (TiO2) nanomaterials in the remediation of the aquatic environment contaminated with various emerging pollutants. The advanced oxidation process led by the semiconductor TiO2 is an impetus in the remediation technology. Therefore, a vast number of literature works are available in this area. Further, the role of modified TiO2 or thin film materials were discussed in the review. Also, the Localized Surface Plasmon Resonance (LSPR) effect of using noble metaldoped TiO2 played an interesting role in the remediation process.
