Titania nanotubes with aminated reduced graphene oxide as efficient photocatalysts for antibacterial application under visible light.

ABSTRACT: Titania and reduced graphene oxide (rGO) are well-known materials with excellent photocatalytic properties, but research on the photocatalytic-based antibacterial effects of their combination remains limited. This study explored the suitability of titania nanotubes (TiO₂ NTs) combined with rGO and two terminal functional groups (nonfunctional and aminated groups (NH₂)) as efficient photocatalysts for antimicrobial applications under visible light irradiation. Field-emission scanning electron microscopy observations revealed that rGO covered the entire surface of the TiO₂ NTs. Tauc plots calculated from the spectra of diffuse reflectance spectroscopy showed that the band gaps of the nonfunctional and amine functional groups of rGO-coated TiO₂ NTs
