Electroless Ag nanoparticle deposition on TiO2 nanorod arrays, enhancing photocatalytic and antibacterial properties
The Ag nanoparticle content was controlled by the Ag deposition process. The TiO<sub>2</sub>/Ag nanorod array containing 6.6 atomic% Ag as nanoparticles of ∼ 25 nm in diameter degraded 88 % of the RhB in 6 h compared to 54 % degradation for bare TiO<sub>2</sub> nanorods under the same reaction conditions. Decreased photoluminescence with heterojunction formation would indicate electron transfer from the TiO<sub>2</sub> into the Ag nanoparticles, thereby reducing charge carrier recombination. The antibacterial test conducted in the dark revealed enhanced performance for the TiO<sub>2</sub>/Ag sample compared to TiO<sub>2</sub> nanorods against Methicillin-resistant Staphylococcus aureus after 16 h exposure with a death rate of 84 %.
