Effect of Gold Dispersion on the Photocatalytic Activity of Mesoporous Titania for the Vapor-Phase Oxidation of Acetone

Figure 7

Yield of CO₂ (curves (a)–(c)) and C₂H₆ (curve (d)) as a function of time, when mesoporous TiO₂ (sample T1) was used for the UV-induced vapor-phase photocatalytic oxidation of acetone present at varying concentrations in air. (a) 2.7, (b) 5.3, (c) 10, and (d) 13 mol%.
