Titanium oxide-based nanomaterials (TiOBNs) have been widely utilized as potential photocatalysts for various applications such as water remediation, oxidation, carbon dioxide reduction, antibacterial, food packing, etc. The benefits from TiOBNs for each application above have been determined as producing the quality of treated water, hydrogen gas as green energy, and valuable fuels. It also acts as potential material protecting foods (inactivation of bacteria and removal of ethylene) and increases shelf life for food storage. This review focuses on recent applications, challenges and future perspectives of TiOBNs to inhibit pollutants and bacteria. Firstly, the application of TiOBNs to treat emerging organic contaminants in wastewater was investigated. In particular, the photodegradation of antibiotics pollutants and ethylene using TiOBNs are described. Secondly, applying TiOBNs for antibacterial to reduce disease, disinfection, and food spoiling has been discussed. Thirdly, the photocatalytic mechanisms of TiOBNs to mitigate organic pollutants and antibacterial were determined. Finally, the challenges for different applications and future perspectives have been outlined.
