ResumoOrganic contaminants (textile dyes, pesticides) in industrial wastewater have adverse effects on the environment and human health. Such environmental pollutants are resistant in the environment and are difficult to completely remove through treatment techniques. Therefore, titanium dioxide (TiO2) nanostructure-based photocatalytic processes have received much attention due to their environmentally green nature with high efficiency for complete photodegradation of organic pollutants to produce safe and clean water. In this chapter, zero-dimensional to three-dimensional TiO2 nanostructures functionalized with various polymeric and nanocarbon hybrid materials are discussed as low-cost, nontoxic, and highly efficient photocatalytic materials for photodegradation of chemical pollutants, in comparison with pristine TiO2, through expansion of the visible light photoresponse and regulation of the bandgap propertiesBand gap properties of TiO2. Various chemical synthesis methods, surface modifications with various polymers and nanostructured carbons, compositions, morphological structures, growth mechanisms, physicochemical properties, electronic and optical characteristics, and photocatalytic mechanisms (e.g., reactive oxygen species generation) of various heterostructured TiO2-based photocatalysts are discussed in terms of their prospects and future challenges in the fields of photocatalytic environmental remediation and hydrogen generation.
