The energy band gap was effectively narrowed to ~ 2.98 eV. 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. | URI: | http://hdl.handle.net/10397/43424 | ISSN: | 1566-7367 | DOI: | 10.1016/j.catcom.2015.09.014 |
