Ag promotion of TiO 2 -anatase disinfection capability: Study of Escherichia coli inactivation

Ag promotion of TiO 2 -anatase disinfection capability: Study of Escherichia coli inactivation In this report we investigate the promotion of the TiO 2 -anatase disinfection capability by addition of silver. Ag–TiO 2 systems were prepared by two different methods, impregnation and photodeposition, and their anti-microbial properties analyzed as a function of the silver content using Escherichia coli as a benchmark microorganism. Both Ag–TiO 2 series of samples display maximum photokilling activity for a 1 wt.% silver loading but behave very differently for higher silver loadings. The noble metal roles played on the E. coli inactivation and their physical grounds were analyzed by a multitechnique approach using XRD, and Raman, UV–vis and electron paramagnetic resonance (EPR) spectroscopies. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Catalysis B: Environmental Elsevier

Abstract

In this report we investigate the promotion of the TiO 2 -anatase disinfection capability by addition of silver. Ag–TiO 2 systems were prepared by two different methods, impregnation and photodeposition, and their anti-microbial properties analyzed as a function of the silver content using Escherichia coli as a benchmark microorganism. Both Ag–TiO 2 series of samples display maximum photokilling activity for a 1 wt.% silver loading but behave very differently for higher silver loadings. The noble metal roles played on the E. coli inactivation and their physical grounds were analyzed by a multitechnique approach using XRD, and Raman, UV–vis and electron paramagnetic resonance (EPR) spectroscopies.
