Sustainable pollutant removal and wastewater remediation using TiO2-based nanocomposites: A critical review

Rapid industrialization and urbanization emphasized water purification and the production of carbon-neutral fuels. State-of-the-art technology that is low-cost, long-lasting, and easy to implement is required to address these issues. In this context, substantial developments in green synthesis technology have provided a more efficient, effective, and affordable procedure. One possible paradigm worth considering is a circular system that purifies water and produces biomass. Titanium dioxide-based photocatalysts (TPs) can be a great tool due to their outstanding properties, which can be modified for improving photocatalytic activities in various advanced oxidation process applications. In recent years, there has been a significant increase in the attention given to the development of environmentally sustainable TPs. A comprehensive analysis of nearly 300 academic articles in this…
