Assessment of the Effect of Zn Co-Doping on Fe/TiO<sub>2</sub> Supports in the Preparation of Catalysts by Wet Impregnation for Photodegradation Reactions of Food Coloring Effluents

Assessment of the Effect of Zn Co-Doping on Fe/TiO<sub>2</sub> Supports in the Preparation of Catalysts by Wet Impregnation for Photodegradation Reactions of Food Coloring Effluents

This study explores the photocatalytic efficiency of Zn/Fe/TiO<sub>2</sub> catalysts, synthesized via the wet impregnation method, for degrading the food colorings Allura Red and Tartrazine Yellow. A 2<sup>2</sup> factorial design with a central point replication guided the c...
