dc.description | For the first time, Evonik P-25 nanoparticles were impregnated with tungstophosphoric acid (TPA) (30% w/w) and annealed at two different temperatures, 200 °C (P25-TPA-200) and 500 °C (P25-TPA-500) for 1 h. Samples were characterized by different analytical techniques. Their photocatalytic activity was evaluated in the degradation of malachite green (MG) solutions at pH 5.0 upon three different irradiations: λ1 > 320 nm, λ2 > 450 nm and λ3 > 590 nm. Only sample P25-TPA-500 showed visible-light absorption. This absorption could be related to the formation of a surface complex TPA Keggin anion-TiO2. P25-TPA-500 and P25-TPA-200 samples showed an important dark adsorption of MG dye (∼30%); however, sample P25-TPA-500 exhibited the highest photocatalytic activity either under irradiation λ1 or λ2. The presence of tert-butyl alcohol (TBA), an OH scavenger affected the photocatalytic reaction upon irradiation λ1, but just slightly upon irradiation λ2. Finally, P25-TPA-200 exhibited a higher leaching of TPA than P25-TPA-500 samples. | - |
