TY - JOUR T1 - TiO(2) Nanotube/CdS Hybrid Electrodes: Extraordinary Enhancement in the Inactivation of Escherichia coli JF - Journal of the American Chemical Society Y1 - 2010 A1 - Hayden, S. C. A1 - Allam, N. K. A1 - El-Sayed, Mostafa A AB - Titanium dioxide nanotubes offer distinct advantages over films of the same material in the production of hydroxyl radicals and subsequent inactivation of Escherichia coli in wastewater. However, their visible light absorption capabilities are limited. Semiconducting nanocrystals of cadmium sulfide have been used to increase the sensitivity of TiO(2) nanotubes to visible light. A small applied potential, using CdS-coated TiO(2) nanotube arrays, allowed for total inactivation of E. call in hitherto record short time. VL - 132 SN - 0002-7863 N1 - Hayden, Steven C.
