Visible light photodegradation of dyes over mesoporous titania prepared by using chrome azurol S as template

Visible light photodegradation of dyes over mesoporous titania prepared by using chrome azurol S... Mesoporous TiO2 with anatase crystalline structure (MTiO2/CAS) has been synthesized by using chrome azurol S (CAS, 2″,6″-dichloro-3,3′-dimethyl-4′-hydroxy-3″-sulfofuchson-5,5′-dicarboxylic acid) as template. It was characterized by X-ray diffraction, nitrogen adsorption/desorption, diffuse reflectance UV–visible and FT-IR spectrometry, and transmission electron microscopy. It was found that MTiO2/CAS had substantial photocatalytic activity in the degradation of methylthionine chloride, rhodamine B, gentian violet, safranin T, methyl violet, and fuchsine basic whereas Degussa P25 (P25) had negligible photodegradation yield (<6%) under visible light irradiation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

Mesoporous TiO2 with anatase crystalline structure (MTiO2/CAS) has been synthesized by using chrome azurol S (CAS, 2″,6″-dichloro-3,3′-dimethyl-4′-hydroxy-3″-sulfofuchson-5,5′-dicarboxylic acid) as template. It was characterized by X-ray diffraction, nitrogen adsorption/desorption, diffuse reflectance UV–visible and FT-IR spectrometry, and transmission electron microscopy. It was found that MTiO2/CAS had substantial photocatalytic activity in the degradation of methylthionine chloride, rhodamine B, gentian violet, safranin T, methyl violet, and fuchsine basic whereas Degussa P25 (P25) had negligible photodegradation yield (<6%) under visible light irradiation.
