| Summary: | In recent years, visible-light-driven eco-friendly titania-based photocatalytic nanocomposite materials innovations have sparked a lot of interest in environmental applications such as water treatment, hydrogen production, and sensing to clinical and health monitoring. Many appealing physio-chemical properties are viable with the advent of such materials. However, despite the frontier of research on titania-based nanocomposites rapidly expanding, transforming the technology into the market or large-scale applications is still an open issue due to their performance/cost trade-off factor. From this perspective, researchers working on the development of titania-based materials towards more reliable and better performance in terms of under solar light by altering the energy structures of titania are modified primarily by adjusting the crystal structures and surface properties by using different strategies such as elemental doping and composite materials. Hence, this review mainly focuses on the novel strategies adopted for the realization of improved titania-based nanocomposite products for environmental applications.
