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...
