Title
Photocatalytic degradation using tungsten-modified TiO2 and visible light: Kinetic and mechanistic effects using multiple catalyst doping strategies
Abstract

Tungsten-modified titanium dioxide catalysts prepared from sol–gel methods and obtained commercially were compared for their photocatalytic activity using mechanistic probes designed to examine chemical pathways of oxidation. No special visible absorbance was noted for the sol–gel catalysts. However, an increase in the single-electron transfer chemistry with the presence of WOx was noted, and a distinct wavelength dependence on the product ratios.
