Abstract

A visible light photocatalyst based on palladium oxide nanoparticles dispersed on nitrogen-doped n-TiO2 was reported. The strong anti-microbial effects of TiON/PdO photocatalyst under visible light illumination and their post-illumination activity provided various opportunities such as continuous solar-powered disinfection during daytime and at night, for a wide range of environmental applications. TiON/PdO photocatalytic fibers were synthesized by a sol-gel process. Titanium tetraisopropoxide (TTIP), tetramethylammonium hydroxide (TMA), and palladium acetyacetonate (Pd(acac) 2) were used as precursors to provide titanium, nitrogen, and palladium sources. The resulting combination of photocatalytic and post-illumination catalytic properties of these materials made them best suited for solar-based systems.
