Description:

The flame-synthesized catalysts have higher surface areas than commercial-grade titania and are composed of nanometer-sized primary particles with low internal porosity. Preliminary studies suggest that flame-synthesized iron-doped titania may be photoactivated in the visible light region but its photocatalystic activity is decreased with the increase of doping amount. To examine the decrease of the activity, other transition metal species, such as Co, Mn could be used as doping species in the flame synthesized titania. The oxidation efficiencies of different film reactors are compared for certain partial oxidation processes. The catalyst characterizations are conducted with respect to surface and optical properties. Phase compositions, morphologies, particle sizes, XRD patters, and optical properties of those flame-synthesized doped titania are established. The effectiveness of these different catalyst at degrading phenol in aqueous solutions is reported.
