Collection optics of TiO{sub 2} photocatalyst on hollow glass microbeads floating on oil slicks
- Univ. of Texas, Austin, TX (United States)
We analyze the optics of sunlight collection in hollow glass microbead attached TiO{sub 2} particles floating on oil slicks, photoassisting their dissolution. This technology uses glass microbeads that float on the oil slick. The microbeads are partially coated with a layers of 3.0-3.3-eV bandgap TiO{sub 2}, a known catalyst for the photoassisted oxidation of organics. The fraction of the UV solar irradiance ({lambda} = 360 nm) directly and indirectly exciting the TiO{sub 2} photocatalyst is calculated. It is shown that a glass microbeads collects most of the sunlight, channeling it to the attached photocatalyst particles. Therefore, 30-40% coverage of the microbeads is optimal for photodissolving oil slicks. Here, the collection optics of the floating, coated microbeads is analyzed. 14 refs., 12 figs.
