Plasmonic Au (1 wt%) catalysts deposited on hydrothermally synthesized TiO2 nanorods (TNR) were investigated in this study. Based the duration of mixing precursor/TNR suspension during wet impregnation synthesis and parameters end calcination, Au/TiO2 with different sizes nanoparticles (Au NPs) obtained. The prepared solids thoroughly characterized by several instrumental techniques to investig...

Using hexavalent chromium [Cr(VI)] and methylene blue (MB) as model substrates, we discuss three aspects of TiO2-based heterogeneous photocatalysis. We show first that a given TiO2 sample may not be simultaneously optimal for photocatalytically driving the reduction of Cr(VI) and the oxidation of MB. We further show that a TiO2 sample that strongly adsorbs either of these substrates in the dark...
