Abstract:Buoyant cenosphere loaded TiO 2 photocatalysts were prepared and the nanosized TiO 2 particles were characterized by XRD, BET, TEM and SEM. The photocatalytic decomposition of crude oil contamination on water has been studied. Experimental results show that Fe 3+ doped TiO 2 catalyst has higher photoactivity than undoped TiO 2. After irradiation for 8 h under a high pressure mercury lamp, the decomposition rate of crude oil on water reaches about 75%.
Keywords:photocatalytic decomposition  crude oil contamination  buoyant cenosphere  titanium dioxide
