Effect of cold plasma pre-treatment on photocatalytic activity of 3D fabric loaded with nano-photocatalysts: Response surface methodology

- The potential of immobilized TiO2 and ZnO nanophotocatalysts for the removal of reactive dye was investigated.
- Optimum decolorization conditions have been determined.
- The immobilized nanophotocatalysts decolorized azo dyes completely from a textile effluent within 60 min.
- Photocatalytic decolorization rates obeyed the pseudo-first-order rate.
