| Popis: | This paper demonstrates the successful synthesis of TiO2 with (001) crystal plane; its morphology and structure were characterized using XRD, TEM and Raman spectrometer. The results showed that TiO2 nanosheets were bounded by (001) facets on both the top and bottom. TiO2-001/UV photocatalytic process was proved to be a powerful method for degrading tri(chloro-propyl) phosphate (TCPP) in aqueous solution. Under the given parameters, 95% of TCPP was removed in 360 min. The photodegradation followed the pseudo-first-order kinetic reaction. The reactive species during photocatalytic oxidation of TiO2-001 was mainly hydroxyl radical. TCPP was decomposed into small molecule organics by hydroxyl radicals, along with the release of PO43- and Cl-, and most of these intermediates were eventually degraded into carbon dioxide and water. |
