Visible-light-sensitive sub-5nm anatase titanium dioxide (TiO2) nanoparticles (NPs) were fabricated without any doping and calcination treatments. The energy band gap was effectively narrowed to ~2.98eV. The surface and subsurface hydroxyl defects were ascertained as the origin for the band gap narrowing and for the efficient azo-based dye degradation in water and formaldehyde decomposition in air, as well as disinfection of Staphylococcus aureus bacteria, under visible light irradiation.
