On the Photoassisted Hydrogen Production from Titania and Water.
Abstract
When TiO2, reduced by H2 or CO, is placed in an ambient of gas phase water and illuminated with band gap light, H2 is evolved. Adding a small amount of O2 completely retards this reaction. A dark reaction of reduced TiO2 with water to form H2 also occurs at temperatures above 200 C. These results show that H2 evolution is not the result of catalytic water photolysis but a photoassisted reaction of water with oxygen vacancies produced by the reduction. (Author)
