Photocatalysts for the Destruction of Styrene as an Air Pollutant

Various photocatalysts have been produced for the oxidation of airborne styrene. Commercial Degussa P25 (supported on vanadia-doped/undoped silica gel) and synthesized titania-pillared clay was used. Selected catalysts were characterized using SEM, TEM, XRD, TGA, UV-vis spectrophotometry, and nitrogen adsorption. This work represents the first phase of a study, aimed at degrading styrene in a fluidized-bed photoreactor, of which will be reported separately.
