Abstract:In this research, selected catalytic activity conditions of nano Cu‐TiO2 films were evaluated through a 2IV4−1 Fractional Factorial Design for methylene blue discoloration. The following conditions were set at two levels: dye concentration (mg/L) (A) at 3.13 and 5.81; aeration (psi) (B) with and without; radiation (nm) (C) at 320 (UV) and 470 (Visible); and nano‐TiO2 films (D) without and with Cu‐doping. Films were prepared by the Sol‐Gel dip‐coating method and characterized using X‐ray diffraction, revealing … Show more
