Magnetic Ag-TiO2-FeOx nanotubes induced a 6log10 reduction of E. coli within 1 h.
The bacterial reduction time was much faster compared to TiO2 and Ag-TiO2 nanotubes.
The magnetic Ag-TiO2-FeOx nanotubes were easily harvested after bacterial reduction.
Bacterial reduction occurred with leaching out ppb amount of Fe and Ag-ions.
