LONG-LIVED HIGH VOLUMETRIC ACTIVITY PHOTOCATALYSTS |
摘要 |
The present disclosure relates to nanocrystalline titanium dioxide (TiO2) photocatalysts having nanocrystallites of less than 14 nanometers in diameter, which are substantially defect-free. The TiO2 photocatalysts form porous particles having a very large mass transfer surface area, large cylindrical pores, and low mass transfer resistance. The nanocrystalline TiO2 photocatalysts provide at least 75% of the photocatalytic activity of commercially-available TiO2 crystals having diameters greater than 20 nm. The nanocrystalline TiO2 photocatalysts may be doped with a metal, metal oxide, or non-metal dopant. A process for preparing the nanocrystalline TiO2 photocatalysts is disclosed. The present disclosure also provides methods for using nanocrystalline TiO2 photocatalysts to remove contaminants. |
