| Popis: | http://www.sciencedirect.com/science/article/pii/S1875389211006365; International audience; The aim of this study was to realize catalytic depositions of commercial titane dioxide on classic glass plates by the PMTPmethod, Previed Made Titanium Powder, and to characterize these deposits by MEB and DRX. As confirmed by SEM, three successive layers of photocatalyst are obtained on the glass plates in a quite homogeneous phase as well as it is confirmed that the anatase accounts for 75% after the calcination treatment by the PMTPmethod. The photocatalytic reactivity is evidenced with the determination of the rate constants of degradation of the dye cibacrongreenRG12, used as target, on the fixedTiO2 bed (0.010 min-1) compared to the direct photolysis in homogenous aqueous phase 0.001 min-1. Optimization of the process was explored by studying the dependence of the liquid flow rate and the absorption of photon by the photocatalyst on the kinetic rate constants of the dye photodegradation. |
