摘要：
Noble metals, usually platinum or palladium, supported on titania are commonly used to improve the effectiveness of photocatalyst in decomposing aqueous solutions of organic compounds. 0.5 and 2% platinum supported on TiO2 (P25 - Degussa) and 10% TiO2 supported on SiO2 appeared to be very active in powerful oxidation of Tritons, nonionic surfactants, dissolved in water. A platinum-promoted photocatalyst was by about 20% more active than TiO2 alone. Titania supported on silica makes Pt/TiO2/SiO2 pholocatalyst reusable because it can be very easily separated from aqueous solution after decomposition process.
