Study of the visible light activity of Pt and Au-TiO2 photocatalysts in organic pollutants degradation

Cubillos Lobo, Jairo Antonio Murcia Mesa, Julie Joseane Guarín Romero, Jhonatan Ricardo

Los fotocatalizadores Pt-TiO2 y Au-TiO2 se prepararon por fotodeposición del metal noble sobre el TiO2 sulfatado. Se encontró que las propiedades ópticas, el estado de oxidación y el tamaño de partícula de las especies metálicas (Pt o Au) juegan un papel fundamental en la actividad fotocatalítica del TiO2 bajo luz visible. La actividad...

Powder and Nanotubes Titania Modified by Dye Sensitization as Photocatalysts for the Organic Pollutants Elimination

Murcia Mesa, Julie Joseane Ávila Martínez, Elsa G. Rojas Sarmiento, Hugo Alfonso

In this study, titanium dioxide powder obtained by the sol-gel method and TiO2nanotubes, were prepared. In order to increase the TiO2 photoactivity, the powders and nanotubes obtained were modified by dye sensitization treatment during the oxide synthesis. The sensitizers applied were Quinizarin (Q) and Zinc protoporphyrin (P). The materials...
