Titanium dioxide (TiO2) as a photocatalyst has been ubiquitously studied for environmental applications. Though, readily available, nontoxic, and environmentally friendly; lower efficiency, less energy harvesting within the UV-Vis range with the ease of photogenerated charge recombination is still a concern for its full-scale deployment as a photocatalyst for environmental remediation applications. In the light of this, this mini review considers heteroatom doping, dye/metal sensitization, metal oxide/semiconductor coupling, heterojunction constructions, surface morphology regulation as well carbonaceous and other nanomaterial hybrids for the improvement of TiO2 photocatalytic activity performance efficiency in the removal of contaminants of emerging concern (CECs) from aqueous systems.
