Overview

Randomized trial measures dye degradation in textile effluents, indicating effective treatment potential.

Key Points

  • This work aims to evaluate the photocatalytic performance of ZnO/NiFe2O4 nanocomposites for dye degradation.
  • Synthesized ZnO/NiFe2O4 nanoparticles using a chemical one-pot technique.
  • Characterized morphology with field emission scanning electron microscopy (FESEM) and phases using X-ray diffraction (XRD).
  • Assessed photocatalytic activity with methylene blue and eosin yellow dyes under visible light.
  • Optimized nanocomposite degraded 85% of methylene blue and 84% of eosin yellow under visible light.
  • Reaction rate constants were 0.0246 min−1 for eosin yellow and 0.0249 min−1 for methylene blue.
  • Elimination mechanism involved •OH radicals and photo-induced holes.
