Performance in a fluidized bed reactor of photocatalysts immobilized onto inert supports
(Elsevier Science, 2000-05)
The performance of amodel photocatalyst (Degussa P25), immobilized onto quartz sand using a dry/wet physical deposition method has been studied in a fluidized-bed reactor. A simple model substrate, dilute oxalic acid, was ...
Hybrid photocatalysts for the degradation of trichloroethylene in air
(ELSEVIER SCIENCE BV, 2009)
Hybrid photocatalysts based on an adsorbent SiMgOx and a photocatalyst TiO(2) were developed in a plate shape. The ceramic surface was coated with TiO(2) by the slip-casting technique. The effect of the support in the ...
Fluidized bed photoreactors using composites of titania CVD-coated onto quartz sand as photocatalyst: Assessment of photochemical efficiency
(Elsevier Science Sa, 2006-12)
The photochemical efficiency of a fluidized bed (FB) of quartz sand coated with TiO2 by plasma-CVD, was investigated using a fully illuminated, parallel planar photoreactor. The local volumetric rate of photon absorption ...

Photocatalytic reduction of Cr(VI) in a fully illuminated fluidized bed reactor
(Iwa Publishing, 2011-08)
The potential of a fluidized bed reactor for the UV-A photocatalytic reduction of Cr(VI), a priority water pollutant, by utilizing a TiO2/quartz sand composite, was explored. The effects of oxalic acid (OA) as a sacrificial ...
Optical and Physicochemical Properties of Silica-Supported TiO2 Photocatalysts
(Wiley, 2006-12)
Commercial applications of photocatalysis in slurry reactors employing titanium dioxide particles present the disadvantage of the additional cost associated with the downstream catalyst separation. In past years a significant ...
