Binary visible-light-activated ZnO/CuCo۲O۴ photocatalysts for degradation of Congored dye through persulfate activation

In this study, we invastigated photocatalytic performance of ZnO/CuCo۲O۴ nanocomposites undervisible light in removal of Congo red using persulfate anions. Among the fabricated materials, theZnO/CuCo۲O۴ (۲۰%) nanocomposite presented the best performance. The photocatalytic removal rateconstant in the ZnO/CuCo۲O۴ (۲۰%)/persulfate/Vis system was ۳۸.۹, ۵.۵۲, and ۱.۵۴-folds higher than theZnO, ZnO/persulfate, and ZnO/CuCo۲O۴ (۲۰%) systems, respectively. Furthermore, the photocatalystpresented good reusability in the photocatalysis processes.
