Au nanoparticle sensitized blue TiO₂ nanorod arrays for efficient Gatifloxacin photodegradation.

ABSTRACT: TiO₂ nanorod arrays have been widely used in photocatalytic processes, but their poor visible light absorption and rapid carrier recombination limit their application. Both introducing oxygen vacancies and using precious metals as surface plasmon resonance (SPR) stimulators are effective strategies to enhance their photocatalytic performance. Herein, Au nanoparticle sensitized blue TiO₂ nanorod arrays (Au/B-TiO₂) were successfully fabricated for efficient Gatifloxacin photodegradation. The degradation efficiency of Gatifloxacin was up to 95.0%. Moreover, the corresponding reaction rate constant (K_a) was up to 0.02007 min^-1. Additionally, it was suggested that Gatifloxacin could be subject to three different degradation pathways.
